It is used to open a tapped hole for wiring fixing when wiring to assembled equipment later. I am thankful that I can open it in a place I could not open until now but greedy comes out and it will be even shorter, will it become like I can be put in a narrow place · · ·. Moreover, although it is useless with the product of this hand originally, since it uses it in a narrow place, it is a place where it is worrisome that it is difficult to force easily by any means. However, I think that the current technology is the maximum thing.
I thought that it was very good as I saw the goods that arrived, so I thought that it was very good, I think that there is no difference in material and durability that is different from the drill body I have, nothing is rattling during use I feel that there is a sense of unity and I think that it is a very good product, if you buy an L type this is it.
