I am using it without problems. I attach it to an electric screwdriver and it is useful for a little drilling etc.

It is useful because it can open a hole of a size not found in an ordinary set of drills. It is considerably cheaper than a nearby home center.

It would be fine if a step drill starting from a 3 mm diameter was in the monotaro brand, but since it was not, it was made to this size. Especially, it is a normal drill, not being sharp even with good eating.

Is good. It was used for steel (2 mm thick). Sharpness is too good, so you need attention.

With a drill on hand, I could only open holes up to 6.5 mm, I was extending with a ruther, but now I can easily open large holes using this. It is very convenient.

It is quick to get sharp. I want a little more strength because the blade does not grind.
Drilling and expansion of plastic cover

I was able to extend to the size as I thought with a light power. For now it's only a plastic drilling, but it's very convenient.

I bought it to make a hole in a steel plate at a business trip site. If this is so, it will be handy because you can expand the hole step by step without lots of drills and holesaws.
