Used for chamfering after drilling.

It is convenient because it can be extended and used. Durability seems to be somewhat bad.

Part of the head feels big and heavy! I would like to use it for chamfering about 10 mm hole, so I think that it would be nice if there is a little smaller size.

Until now, I was substituting for a drill blade, but because this product can handle a wide range widely, it was nice to buy!

It's the first use, but it's a handy tool that's easy to use. Unlike the type that you can wear to the tip of the drill, you can reduce it.

Used for chamfering holes in plastic items
From Japan

It is written as use range 1 ~ 20 mm, I bought it because I want to use from φ 1, but the tip is for safety, the blade is crushed and it can not be used unless it is from φ 2. Since sharpness is good, returned goods have been sent off. I would like to change the display or make it available to the tip.

I am going to use cheap here because it can be used as well as a maker's item.
