I bought it to open a hole 4 mm deep in free-cutting brass material.

I was using a micro drill of HY 's so far, but I was puzzled because this micro drill MD is super hard.
Since the number of revolutions of the drilling machine being used is extremely low and it is about one thousand hundreds of revolutions, it is necessary to apply stenorolin to make sure to clean the facet every 1 mm in depth, but since the cutting edge is long, it is necessary to make a deep hole Also, it is useful.

As young workers often break because they are thin drills, it is saved for cheapness.

It is very easy to break and easy to set in pin vise because the shaft is also thick. I am happy that the variety is rich and the price is affordable.
Plastic model production time

When manufacturing the car's plastic model, various wires are attached to the wiring and piping of the engine, but we use this drill, which is difficult to pass through the drill hole with the same diameter as the wire rod.
Work efficiency is considerably different only when the hole diameter is 0.05 mm larger.
I am using it pleasantly.

I am using it for nozzle tip cleaning. I was looking for this thin and durable.
Nozzle production of 3D printers

When carbon reinforced PETG filaments are printed with a 3D printer, brass nozzles will wear out for several days and stainless steel nozzles will wear out in a few weeks (both inside and outside surfaces). Therefore, I thought about making nozzles by scraping cobalt drill (HSS - CO). I tried cutting wheels and HSS - CO during cutting and outer surface processing, but efficiency was poor or the blade did not stand. The only thing that I could practically shave was super hard. Although the outer surface was abraded normally with a carbide tip, a carbide drill was also necessary for drilling (0.2 mm), and it worked without difficulty using this product. Up to now we purchased about 20 (0.1 to 0.6 mm), but nothing broke during work. However, it is often thin, so it often breaks into and out of the case or collision with a hand or other tool. You have to be careful with this. Because the price is cheap, it is good to have as many reserve as possible.

Drilling of SCM, S45C bolt.

I thought that it was unsuitable for steel materials because it was φ0.2, but I did a work of 1 millimeter deep into Crobbol without difficulty. Since it can be used without cemented carbide, it is available in COSPA.
