I use it attached to an electric drill.
Do not forget to add drilling oil and use it for long lasting.
Threading work of DIY

Because it is DIY work by individuals, it can be used without problems. In addition to this I bought a ratchet handle. Spiral is easier when operation is lighter and easier when there are many numbers. When you want to thread thoroughly, use a normal tap.

It is a good item than expected. There is no problem at all with regard to use.

A slight crunch sound comes out even with stainless steel or low carbon steel, the current usage situation makes the pilot hole slightly larger.

Although it is cheap, it cuts well. I want you to make M2 M1.7 M1.4.

Although I use it every time as a repeat item, I am using it without any problem, but I feel like I'm having a bad thing from a maker item, but since it is a consumable item, I will also purchase it next time in terms of price.
