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.

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 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.
