How to make an angle grinder from a drill

Factory parts for fixing device

  • In the center, you see the drive shaft for an angle grinder from a conventional drill, on which the cutting or grinding disc will be clamped. The factory version provides for the presence of splines and / or grooves for fixing the lower flange and a thread for a clamping nut-washer, which, in fact, can also be called a clamping flange.
  • On the left is the bottom flange, which simply slides over the grooves or splines of the shaft, so it rotates with it. On the flange there is a landing protrusion of a certain diameter on which the disc is put on. This flange in the assembly performs the function of a reduction. an adapter from one diameter to another. Due to this, the saw or grinding disc will have a strict alignment when rotating.
  • On the right you can see a clamping nut for an angle grinder from a drill, but it is also made in a special way. In the center there is a groove corresponding to the diameter of the small reduction. It is needed in order to press the disc, but at the same time not to rest against the landing protrusion.

Note: all additions with reduction lugs and holes are necessary here, since the thread on the drive shaft is M14, and the inner diameter of the disc is 22.23 mm.

Step by step assembly and selection of parts

So, if you are planning to make an angle grinder out of a drill, then decide what you intend to cut, that is, will it be sheet metal or reinforcement, and what thickness will they be? For a steel rod, if it is, of course, one-time chopping work, the power of a cordless drill (electric screwdriver), as shown in the top photo, is quite enough. Only for thick metal. from one millimeter or more, you will need a wire drill with a capacity of at least 700-750 W. The fact is that a wired power tool has a more revving motor than an electric screwdriver and it will be difficult for you to even cut off the fiftieth corner.

If we talk about an electric screwdriver, then an angle grinder will cause problems here not only because it has a low-speed motor, but also because the battery will discharge very quickly under heavy loads. The best batteries of such models as “Makita” or “Bosch” are also not a panacea for long-term use. For example, if “Makita” in normal mode can be used at the facility without recharging the whole day, then as an angle grinder it will last no more than a couple of hours. But this is up to you, and we will talk about the device for fixing the saw blade.

Self-assembly of the fastener

an angle grinder from a drill by the method of fixing the disc is not much different from the fastener in a conventional angle grinder, and you read about it in the section “Factory parts for the fixing device”. We will make the bottom flange and the clamping nut according to the same principle. The photo above shows the bottom flange without a thread, but you will have to cut it for the most reliable fastening. The outer diameter of the flange must be at least 30 mm so that the disc is well supported. The diameter of the protrusion should be slightly less than the inner diameter of the disc, that is, if the disc has Ø22.23 mm, then on the reduction Ø22.0 mm. this is necessary for free sliding.

Now let’s move on to the flange nut. In order not to use a special wrench, the clamping flange can be turned from a hexagonal rod with a thickness of 27-30 mm, but before cutting the internal thread M14, you need to make a recess of Ø23.0 mm so that the nut does not touch the reduction lug. On a lathe, such a recess can be easily made with a Ø23.0 mm drill to a depth of 2-3 mm. After that, cut a blank nut 7-8 mm thick and cut an M14 thread in it. That’s it, the angle grinder from the drill is ready to use.

Note: keep in mind that using a drill instead of an angle grinder is almost impossible in hard-to-reach places.

We put the inner flange on the shaft so that it sits in the grooves, then we twist the outer flange.

Tighten only the outer flange with a special wrench, the shaft is held by an open-end on the back of the inner flange.

After installation, we tighten and install the drill in the chuck, we also tighten the shaft well in the chuck.

Done! Since the drill has a reverse, the working rotation should go clockwise, as when drilling.

The arrows (in the photo) indicate the mandatory direction of movement of the disc, in which case the outer flange with an internal (normal right) thread will tighten by itself and will not unscrew during operation.

The basic rule of working with a power tool is safety, which is not limited to glasses alone.

You ask: “Where can you get the shaft from the angle grinder, if there is no old, faulty one?”

I will share that this season I worked with this device and got a lot of pleasure from the maneuverability and the ability, if necessary, to adjust the speed of rotation of the disk. I think that on occasion, you will appreciate everything yourself.

How to make an angle grinder from a drill

an angle grinder from a drill is easier than the other way around. An angle grinder or angle grinder (angle grinder) has become an indispensable power tool due to the wide range of work that can be done with it, but it has its drawbacks that interfere with work. With its help, it is not always possible to get close to hard-to-reach places and often it has high unregulated speed, by the way, because of this, increased security measures are required. But, despite all this, for certain types of work, it is irreplaceable. We can take advantage of all the advantages of an angle grinder, yes, we can also get around its disadvantages. To do this, it will be enough for us to get hold of a drive shaft with flanges from an angle grinder (I took it from an old, spoiled one).

angle grinder from a drill

Actually, the easiest way is to take some kind of adapter, which on the one hand can be clamped into the cartridge, and on the other, it should be possible to fix the disc.

There are two options here. The first one involves using a spindle from an old angle grinder, which at one end has an M14 thread, where you can attach a disc, and the second end is in the form of a rod, which can be well clamped in a chuck.

The only problem here is finding this spindle. You may have an old broken angle grinder. You can also contact any service center for servicing the power tool. perhaps they have an extra one and they will sell it to you.

Another option is to purchase a grinding disc designed for both of these tools. It has an M14 threaded seat. It is mounted on an angle grinder by simply screwing it onto the spindle. But it is attached to the drill using the adapter included in the kit, which is the same as in the previous paragraph, only without a washer and nut, which in this case will have to be looked for separately.

Well, further actions become clear. We take the adapter, clamp it into the cartridge. And then we attach the cutting wheel to it. So the angle grinder is ready for you.

Well, I hope you succeed. The main thing when working with such a device is not to make sudden movements in order to avoid rupture of the disc. Well, it’s worth working in tight work clothes and goggles. But still, my advice to you is to buy the best inexpensive angle grinder.

Support structure and minor modifications

  • steel strip or bar;
  • welding machine;
  • clamps;
  • pliers.

Almost always, such an angle grinder is made as a stationary tool, therefore, the working surface must be prepared. Any wooden or metal countertop is suitable for it, and metal has an undeniable advantage.

The working platform is bent from a 12 mm reinforcing bar or steel strip (2-3 mm). Outwardly, it should completely follow the contours of the used model, because when immersed, maximum retention must be ensured. Typically, 4 transverse stripes are used to form the contour and 3 perpendicular to them for rigidity. The joint is made using electric arc welding.

After such a bowl is installed on the table, it must be screwed tightly to the surface using bolts and nuts (bolts with only flat heads). The fixation must be sufficiently rigid, therefore at least 4 mounting points.

At the very end, the tool is turned over and lowered into place (handle up). The final fixation is carried out by means of clamps, with which everything is pulled together from 2 sides.

If you have to work with the tool for a long time, then make a protective cover. To do this, it is enough just to cut a piece of sheet steel and bend its edges so that it takes up the entire space above the working area. To fix it to the tool, you need to make a clamp from a steel strip (exactly the size of the drill) and fix it with your own hands.

How to make an angle grinder from a drill: the process of repurposing

  • drill;
  • bar;
  • rasp;
  • grease;
  • angle grinder attachment;
  • ruler.

Before you make an angle grinder out of a drill, you need to make sure that this tool is not needed at this time for other work. After all, assembly and disassembly take some time. an angle grinder from a drill will not be as easy to use.

You can make an angle grinder from a drill with your own hands in a simple way:

  • The attachment for the angle grinder is selected, which will be used for the work. Any option is suitable, because production for one-time work.
  • A steel bar of small diameter is selected, from which an edge must be ground off in order for it to enter the nozzle. Slightly grind off the places of contact between the petals of the chuck and the bar for better adhesion.
  • Fixation.

Here everything is done in a matter of minutes, but immediately after dismantling, the structure will become inoperative, or even completely collapse. A similar revision is done in cases when it is urgently necessary to make an angle grinder from a drill, because the main one is out of order.

The more complex option is not very different, but still there is much more work to be done:

The layout diagram of the “angle grinder” drill: 1. drive (electric drill), 2. work table (duralumin, sheet s5), 3. circular saw, 4. stand (St3, strip 20 × 5, 4 pcs.), 5. mandrel shaft support holder, 6. mandrel, 7. electric drill holder, 8. base plate (furniture chipboard).

  • To begin with, the cartridge is removed. It will now be required only for the reverse restoration, but for now it is advisable to simply clean and lubricate all of its insides. Store only in a dark, dusty place.
  • A nozzle for an angle grinder is selected from durable steel (there are often lightweight options that cannot be installed here in any case).
  • At this stage, you will need a rod of such a length that it extends beyond the drill by 1.7-1.9 cm. Its end is grinded with a rasp so that it ultimately fits perfectly with the socket in the nozzle. Before the joint, you need to use machine oil or any other lubricant.
  • The ball bearing is installed in the place of the outlet, and a bar is threaded through it and fixed in the base. Sometimes this step is not required, so the bar can simply be locked in place.

This method is implemented in a matter of hours, and dismantling and installation of the cartridge in just minutes. After the structure has been assembled 1 time, it will no longer need to be changed or supplemented in the future. It is worth remembering that in this case, protection is not installed, therefore, when working on the sides, there should be no people. You will not be able to injure yourself due to the fact that the disc rotates parallel to the master.

How to quickly make an angle grinder from a drill?

Often in everyday life it is necessary to repurpose the tools, and more often it is the drill that has to be modified, because it is the most versatile tool available. But you must always choose the right tool so that its technical characteristics coincide with the required ones, so that the result will be perfect.

Electric drill device: 1. ventilation grill, 2. power regulator, 3. speed regulator, 4. impact switch, 5. keyless chuck, 6. self-centering cams, 7. chuck mountings, 8. gearbox, 9. fan impeller, 10. electric motor, 11. reverse lever, 12. trigger, 13. cord lock, 14. cord terminals.

Summarizing

There are several options for how to make an angle grinder from a drill, and all of them are quite effective, depending on the tasks at hand. For the resulting tool, it is better not to try to set serious tasks, but it will cope with elementary ones perfectly.

It is best to work on a hard surface as this will significantly increase the safety of activities.

And the most important thing is safety precautions. when repurposing, minor flaws can be made, which will then have a very serious impact.

How to make an angle grinder from a drill?

Hello everyone! In today’s article I will tell you how to make an angle grinder (angle grinder) out of a drill, so that it can not only drill, but also, for example, cut metal.

But first, I will try to dissuade you from this case. Why? Well, because I believe that each tool is intended only for its own business and trying to give it the functions of another, firstly, does not provide a 100% replacement, and, secondly, it almost always leads to unsafe operation.

If we talk specifically about our case, then most drills give out a maximum of 3000 rpm, while for working with a small disc, grinders reach 11000 rpm. That is, the sawing will not be as effective.

As for safety, it is worth remembering that the cut-off wheel for an angle grinder is surrounded by a protective casing, thanks to which sparks and fragments cannot fly in all directions, and it also protects if the disc is suddenly clamped and it breaks. There is no way to adapt the casing to the drill, so safety will be at risk.

If the above reasons do not stop you, then read on.
