How to drill a file

How to drill a hardened file into a light one? A very simple method that will be useful to you in life. A little trick of using a tool for other purposes or not quite for its intended purpose. A short master class on drilling hardened steel.

Drilling a hardened file

So, we fix the file in the vice of the drilling machine. We insert a drill bit into the chuck for glass and tiles. Yes, yes, a drill used to drill glass or tiles.

Spray the drill and the drilling area generously with lubricant.

And we start drilling the hole. Everything is the same as with a regular drill and metal.

After a short drilling, we will raise the joint.

Spray with lubricant again and continue drilling.

The hole is drilled, but not all the way. Since the drill for glass has a cone-shaped solder, the drilled hole, if the drill does not go through completely, will also have a cone shape.

To make the hole even, you need to turn the file over and drill the hole from the back side.

In most cases, craftsmen take a special drill for such things and resharpen it, but I suggested a simpler method.

Why do you need to drill a file?

That's right, there is absolutely no need to drill it! This is just a clear example of how and with what you can drill hardened steel, carbide, and quick cutter.
In general, adopt it, use it, write comments.

A plasma cutter cuts ANYTHING. You don't even need oil. Even a file, even a carbide drill, which is used to drill a file)) It will definitely make a hole, although it will be difficult to call the hole perfectly straight. I make knives from old diamond cutting discs in my free time)))

For strength, files are subjected to carburization rather than hardening. Steel cementation is the surface diffusion saturation of steel with carbon in order to increase hardness and wear resistance.

  Only the shank for the handle is not hardened, but the file itself is completely hardened! And carburization is the surface saturation of steel with carbon! Which reaches a depth of several tenths of a millimeter! This will not work on a file!

  Don’t tell tales. Try to bend any file. If you can, show me.

  Learn the theory, young man. After carburization, the steel must be hardened. It is also subjected to cementation so that it heats up better.

I used to surprise drivers in a production garage by drilling a spring with an ordinary drill from a quick cutter. The secret is simple: rotation - 50--60 rpm; water.

I don't watch the video, I just read. I read a lot and for a long time. The proofreader in me is outraged by the number of stylistic and grammatical errors. Please check your text before publishing.
By the way, thank you for the advice! If I decide to drill files, I will definitely use a carbide cutting tool :)

An ordinary concrete drill drills perfectly into any hardened steel, straight through, with the required hole diameter. You can use it straight from the store, but it’s better to master sharpening for metal drilling. How - look on YouTube on the Exmast channel, there an old turning teacher explains everything perfectly, and, most importantly, shows it.

In everyday life, this knowledge is not needed, but in production, even without such ignoramuses, they know what and how to drill hardened and ceramic-metal products.It would be better to show how to harden a stainless steel knife in a kitchen - it’s quite a task. Many people cut hot potatoes and the knives come loose, they don’t hold the sting, the solution is to re-harden the blade.

Why drill a file: at our factory (the factory has been gone for a long time), improvised large scissors were made from two drilled files, fastened with a bolt and clamped in a vice, with which they cut PVC tubes for tags into wires and cable cores, with ordinary tailoring scissors, PVC vinyl of large diameters in large quantities you'll be tortured to cut, you'll crunch with this same stray without any effort

You can’t drill through either a hard alloy or a quick cutter. When drilling forged steel 45X13, I used up 3 solid-tipped drill bits.

Better than any lubricant is to use a piece of ordinary lard. You can drill with a regular drill, only with a low-speed drill.
