Is it possible to drill metal with a drill

During drilling, you can just burn (lick) the working part of the drill. This is due to huge revolutions, because of which the drill is warming up and melt. This is avoided due to low revolutions or lubrication of the drill with cooling grease.

If there is no special cooling lubricant for drills, you can use machine oil that will lower the friction force.

How to drill metal correctly

Regardless of whether the drill is drilled or on the machine, the main thing is to correctly choose the speed of rotation. Almost always the best speed is in the spectrum of 1800–2500 rpm, but in practice completely different values ​​may be selected depending on the accuracy of sharpening and the parameters of the material.

Effective and brisk drilling can not do without the ability to correctly correlate the speed of rotation and supply effort. Just feel how the drill crashes into the metal, cutting off the chips without abundance, and begins to deepen into the bottom of the hole without significant effort. The turns with all this, usually quite low. About 300-500 rpm.

The best indicator that the drilling process is technologically correct, and the drill is sharpened correctly. A uniform yield of chips from both spiral grooves. The quality of the shavings is also a significant indicator:

How To Drill Holes In Steel. The Ultimate Guide!

  • When drilling steel, whole chips are released in the form of long spirals;
  • Cast iron, hardened steel and other fragile materials form a scattering of needles;
  • Aluminum is drilled with the formation of small curls;
  • When drilling stainless steel, dust and small flakes can be obtained.

If the drill does not crash into the metal, and the gut on it with the corresponding squeak, or at the output, an atypical type of chip appears, it is better to slow down and correct the sharpening, there is a different risk of metal leave from overheating or breaking the working part.

Certainly observing safety precautions! Should be drilled without gloves, protecting the eyes with locksmith glasses.

Before drilling, you need to mark all the holes that must be made in details. The center of each hole should be outlined with a coreer. At first, a small hole is drilled with a depth of 2-3 mm, a few drops of machine oil are introduced into it. It is necessary to learn how to allow the drill to do your job: at first, it is very much crushed by the tool, and when the edges into the metal occur, weaken the pressure and just crush a little, holding the uniform speed of rotation.

Other cooling waters can be used. So, when drilling stainless steel, the drill must be moistened with oleic acid. Its evaporation is harmful, so you need to work in a respirator. Kerosene and soapy water are also great for cooling. A bar of the household per liter.

Drilling metal. Analysis

Increased attention is required at the time the drill is released when drilling through holes. Pretty often in such cases, the thin bottom breaks through the formation of large burrs, which fall into the spiral grooves and tighten the drill forward. At the exit from the part, it is necessary to weaken the pressure and a little increase in speed.

Drilling holes of a huge diameter is better in a few steps, evenly increasing the dialect of the drill. This will not only lower the load on the tool, but also extend the life span and ensure the purity of processing. Holes with a diane of above 13 mm are best drunk with crowns. It is recommended to use consistent lubrication. The crown must at times be given time to cool down, and while working painstakingly, to ensure that the teeth plunge moderately, in other words, keep the spindle strictly perpendicular to the surface of the part.

Ending step of drilling. Removing chamfers on both sides of the hole. To do this, you can use Zenkovka, and in its absence. A drill twice as much as a more dialect, which is served with the least effort at huge speeds. To remove burrs from huge holes, it is appropriate to use a round ratfoll and sandpaper.

Which drill to choose for metal drilling

One of the first questions that inexperienced masterly drill the metal is asked ? In fact, answering correctly not so easy. To process the metal, you need to use special drilling from high.Speed tool steel. In them, the cutting part is made with the addition of nitride titan.

When choosing drill for drilling metals, the main and chassis are drills from high.Speed instrumental steel, in the store they can be found according to HSS.

Drilling into Brick

possible, drill, metal, concrete

When working with cast iron, stainless steel and other metals that are difficult to process, the drill of carbide. Their disadvantage is a very high price, which makes work expensive.

If you choose drills with one of the best cutting properties, it will be a tool with the addition of cobalt, having a marking-P6M5K5. This is the best price and quality ratio.

Is it possible to drill the metal with a drill over the concrete ?

There is a need to make an urgent hole in the metal, and only a drill on the concrete at hand. On such a drill, the tip is made of winning, which makes it possible to drill concrete, brick with a battle. It will not work to use such a drill for drilling a hole in the metal. You can lick the winning tip of the drill, especially if you try to use a large diameter drill or for drilling thick metal. Summing up, it will not work to drill the metal with a winning drill.

However, if it wins to sharpen at the right angle, it is possible to drill metal.

Power and revolutions when working with metal

An important factor is the choice of the tool, namely the penetrator, drill or electric screwdriver, which will be made in the metal. If you use a drill with a power of up to 700W you will not be able to make a large hole at once. A handmill with a capacity of up to 700W is best used to drill holes with a diameter of up to 110-13mm.

It is important to choose the right speed of a drill or electric screwdriver. After all, at high speeds, your drill will simply burn. So you ruin it.

It is necessary to drill metal at low or medium speeds, without exceeding 500-1000 revolutions.

possible, drill, metal, concrete

The larger the diameter of the drill with which you work, the less speed you need to choose.

How to drill metal products correctly

One of the most important parameters with drilling the hole is the sharpness of the drill. If you have purchased one of the cheapest drills, it can be stupid and completely from soft metal, which will not let you do a couple of holes.

How quickly the tip of the drill will be cut and dull, the speed of drilling, the hardness of the metal, the effort of the attached on the drill, and cooling.

  • When drilling large holes, you must first make holes of smaller diameter. So the process will be much faster, and the drills will not be stupid so quickly.
  • For accurate centering the hole, you need to use the core, and tap the center of the hole before drilling.
  • To cool the working part of the drill, you need to use machine oil. Just lower the working part of the drill into a container with butter. Repeat this operation periodically. You can use soapy water for cooling (by reducing friction force).
  • When drilling deep holes, periodically take out the drill and free it from the chips.

How to drill sheet metal

When working with sheet metal, special difficulties should not arise, even when drilling holes of large diameter. The only thing is that you need to put a wooden block under the drilling point, it will help remove the chips. When you feel that you almost drilled a metal sheet-wise pressure on the drill, this will also help reduce the likelihood of a burr.

How to make holes in pipes correctly

The main problem when drilling holes in round pipes is the complexity of perpendicular drilling. This means that the hole from which the drilling began does not correspond to the output. To solve this problem, you need to use a drilling machine, or special guides that you can make yourself or purchase ready.Made.

How to drill aluminum

Who worked with aluminum details knows that this is a soft metal. The main problem when drilling aluminum is the abundant wrapping of the drill chips. Because of this, the drill stops drilling and gets stuck in metal. To avoid this, you need to get a drill from the hole more often and remove the chips.

How to drill stainless steel (stainless steel)

Stainless steel refers to alloy steel, which is not a simple business to perform. In order for the drilling to be comfortable, it is advisable to choose drills with a cobalt tip.

It is necessary to drill stainless steel at minimum speeds, namely 100-200 rpm. Such turns give the desired stainless steel cut and good quality.

If your instrument does not adjust rotation speeds, it is worth pressing the button periodically for a second or two, which will not allow the drill to quickly accelerate.

If you need to make a hole of a large diameter, you need to use crowns for metal, which make it possible to drill only along the outer diameter of the hole.

How to drill holes of large diameter

When you need to make a large diameter in metal, you need to use the tool suitable for this purpose.

  • Previously, you need to make a hole of a smaller diameter. You can use several drills gradually increasing the diameter of the hole. In this way, it will be easier for drills to pass metal, especially thick.
  • Using a step drill. Such drills can be called conical.
  • The use of special metal crowns. The drilling of the holes of large diameter with crowns is given very easily due to the drilling of only the outer diameter of the hole. The crown consists of a centering drill, which initially drills the metal in the center and later directs the crown. Drilling a crown should be done at very small speeds.

Power and revolutions when working with metal

An important factor is the choice of the tool, namely the penetrator, drill or electric screwdriver, which will be made in the metal. If you use a drill with a power of up to 700W you will not be able to make a large hole at once. A handmill with a capacity of up to 700W is best used to drill holes with a diameter of up to 110-13mm.

Revolutions

The larger the diameter of the hole? The less there should be turns. The larger the depth? Thereby gradually reduce the pressure on the drill. With a drill diameter of up to 5 mm, torque should not be higher than 1200-1500 rpm. Respectively, 10 mm in diameter. Not more than 700 rpm, 15 mm. 400 rpm.

As a rule, most of the drifts for domestic use with a capacity of 500 to 800W, which allows you to drill holes with a diameter of up to 10-12 mm. In metal up to 2 mm thick with stepped up, you can make holes up to 40 mm. With a thickness of 3 mm, bimetallic crowns are better suited.

Bimetallic crowns have proven themselves well when working with stainless and carbon steel, non.Ferrous metals. They also cope well with multi-layer materials such as wood, wood-based stove, plywood, plastic, plexiglass, slate.

When drilling deep holes by any tool, you can sometimes need a magnet to extract chips.

Particular attention should be paid to safety precautions, be sure to take care of the chips, and if you go distortion and jamming, immediately turn off the drill and rearrange the torque to reverse movement.

In the absence of electricity or when the noise of a working tool can interfere with others (read: when you can do repairs so as not to quarrel with neighbors?). A manual mechanical drill, the so.Called columnor, is an ideal solution when drilling metal. Low speed and pressure, lack of overheating, just what you need. Of course, there are also disadvantages. Time costs and rapid fatigue. In such a simple “grandfather” way, you can drill holes with a diameter of up to 10 mm.

Drilling thick blanks

If the workpiece has a thickness of more than 5 mm, and you need a hole of more than 8 mm, then it is better to first make a hole with a thin drill, and only then work with a thick.

  • When drilling thick aluminum blanks, chips often clog the drill channels, which is why it becomes more difficult to rotate. Therefore, when working with such material, get a drill from the recess and remove the shavings more often. Well, do not forget to pour abundantly with oil.
  • If you need to drill black cast iron, then for this you do not need to add any lubricating and cooler, since it is very well drilled on dry
  • Unlike black, white cast iron has increased strength, which means that it will require strong drill and lubrication to process it

These are the basic rules for drilling metal with a drill. I hope I managed to eliminate this gap in your knowledge. Good luck at home and see you!

Drilling technology of large and small holes

Review of the technology of drilling holes in metal. How to insert and pull a drill out of a drill, or an electric screwdriver. Epitibritions for using lubrication. Selecting the mode of operation depending on the material. Drilling deep and large holes. Drilling point welding.

Drilling holes in metal is a common technological procedure that can be performed using various equipment. The methods of performance of work differ depending on the given depth, diameter, type of surface, as well as the necessary accuracy.

Drilling technology of large and small holes

Drilling holes in metal is a common technological procedure that can be performed using various equipment. The methods of performance of work differ depending on the given depth, diameter, type of surface, as well as the necessary accuracy.

Drilling methods depending on the type of hole

Competent preparation and the correct selection of equipment will help to drill holes in high quality metal. In addition, the reliability of the drills and the equipment used affects the effectiveness of the operation.

Consider the main types of holes and methods of their processing:

  • Through. This type is characterized by a full passing through the processed workpiece. In the process of performing work, it is necessary to carefully monitor the drill: when exit from the hole, the resistance of the material decreases. If nothing is changed, the tool will drop sharply, which can lead to its jamming or breakdown. To prevent this from happening, use special methods for protecting the countertop or workbench. It can be a multi.Layer lining of wood and metal or a regular bar with a through hole. When using machines at the final stage of the Tokari process, it is recommended to switch to manual feed. Featers are used to process thin.Walled structures, since the classic spiral tool can damage the edges of the part.
  • Deaf. The difficulty of obtaining such holes is the need to control the depth. Modern machines are equipped with a controlled supply system. This allows you to get a hole of a given depth without using auxiliary tools. An alternative way is to use a bushing or adjustable stop. You can use a ruler or special depthmer. The latter option is not popular, since it requires the output of the drill and the removal of the chips to measure the depth, which affects the performance of the work.
  • Complex shape. If there is a need to drill a hole located at the edge of the part, the master should prepare the second workpiece with similar sizes. Two parts are interconnected, clamped in a vice and start work.
See also  How to replace the head with a drill. I beg you, like this post and subscribe to the channel!

The second workpiece should be made of the same material. Otherwise, the tool will shift relative to the axis of drilling towards a softer metal.

Complex processing includes the drilling of cylindrical surfaces. When performing such work, a wood or cork gasket is necessarily used.

  • With ledges. The drill is performed using two techniques: drilling or reducing diameter. In the first case, several drills are used, from less to greater. In the second case, the passage is performed using a tool with the largest diameter. Then the smaller drills with a gradual deepening into the workpiece are used.
  • Large diameter. This procedure is considered very laborious. When processing blanks, the thickness of which does not exceed 8–10 mm, conical and speed drill. This tool allows you to perform a passage with a diameter of 40-50 mm. Special bimetallic crowns are used at metalworking enterprises. With their help, you can get a hole with a diameter of up to 100 mm. Ring drilling is performed at low speeds. This procedure is considered less laborious.

Features of the execution of deep holes will be considered below.

Devices to facilitate the process

The lubricant-cooping liquid is used in many types of metal treatment with cutting. Most often it is used in deep drilling to reduce friction forces and stabilize the temperature of the working tool. High.Quality fluid does not cause surface corrosion, safe for humans, does not have an unpleasant odor and perfectly removes heat.

As a lubricant for drilling metal at home, they use:

  • Technical Vaseline. For soft materials.
  • Soap solution. For aluminum.
  • Sliper with alcohol. For Silumin.
  • A mixture of oils. For instrumental and alloy steels.

Some masters prefer to use the universal composition, which includes laundry soap (200 g) and engine oil (20 g). The components are mixed and boiled until a homogeneous emulsion is obtained.

The use of lubricating and coolest liquids of industrial production allows you to increase the speed of drilling various varieties of metal. For example, when processing stainless steel, performance increases by 30 %. For cast iron, this parameter increases to 40 %.

How to drill a hole correctly

Properly selected tools and technology compliance with qualitatively drill the workpiece even from thick metal. If the depth of the passage exceeds the diameter of the drill by 5 or more times, it is recommended to lubricate moving elements for the removal of heat from the treatment zone.

To obtain a high.Quality hole, the master should know the features of the operation of a drilling tool, as well as the subtleties of the surface preparation before work.

How to insert or extract a drill from a tool

First of all, the master should find out how to insert a drill into an electric screwdriver, an electric drill, a pen or another hand tool.

Modern drilling devices are equipped with cam cartridges. They consist of the following elements:

  • Metal case;
  • A gear ring that rotates around the outer part of the cartridge;
  • Cams located inside the node;
  • Clamping key.

The ring rotates around the axis of the device. In the process of movement, the fists come together, clamping the tail of the drilling tool. So insert the drill into the drill.

This design is highly reliable due to the simplicity of execution. In addition, it allows you to use drill of any diameter. To pull the drill out of the drill, it is necessary to turn the ring in the opposite direction.

Fists will disperse, which will allow you to get the tool.

How to drill metal with a thickness of more than 10 mm with an electric drill?

In metal up to 2 mm thick with stepped up, you can make holes up to 40 mm. With a thickness of 3 mm, bimetallic crowns are better suited.

Bimetallic crowns have proven themselves well when working with stainless and carbon steel, non.Ferrous metals. They also cope well with multi-layer materials such as wood, wood-based stove, plywood, plastic, plexiglass, slate.

When drilling deep holes by any tool, you can sometimes need a magnet to extract chips.

Particular attention should be paid to safety precautions, be sure to take care of the chips, and if you go distortion and jamming, immediately turn off the drill and rearrange the torque to reverse movement.

Time costs and rapid fatigue. In such a simple “grandfather” way, you can drill holes with a diameter of up to 10 mm.

We hope our tips will be useful to you.

Errors when working with a drill

In no case do not try to hold the rotating cartridge with your hand. There is a drill case for this. Otherwise, you can injure yourself. If you use gloves. Do not take “with a margin”. Gloves that are not suitable in size can also get into the cartridge and cause injury. Overalls should not hang out. They can be rolled up or pressed with overshielders.

You can fix a metal sheet or part using a variety of fasteners. However, for them you need to make holes. Drilling holes in metal requires a person to use special tools. To carry out work without difficulty, you need to be able to choose equipment and work with blanks of different sizes.
