Center hole drilling of winding wire type

Since the center is pointed rather than a screw, it is easy to align visually.

I am satisfied with the sharpness, but I am dissatisfied that I can not attach it to the impact

Sharpness is also good, as expected. Especially it is usable without problems.
Acrylic plate 4 mm drilling
On 2018-10-07 22:00:54
I attached it to a drilling machine and used it.
The sharpness was also good, and it was able to be used without problems. We only have about 20 empties yet, but the sharpness does not change.

The cheap woodworking drills that are sold at home centers and 100 yen shops are blunt anyhow, and only slight frictional heat is generated in a slightly consolidated wood, not only does the hole not open at all, fire as smoke rises and the material burned I was worried about getting out, but since this product is not like that indeed, there are no such things, so the woodworking drill is a domestic manufacturer's choice. Although it is also the sharpest point that sharpness falls, it also felt early.

It was easy to use, affordable and very good shopping was made.
Used in drilling machine

It is possible to process holes with extremely accurate sizes.
It is thought that blurring has occurred with the use of a hand drill etc. that holes of the correct size can not be opened.

Because it can be stopped where you want to stop, I use it with my own electric drill drilling machine.

I bought a thing of 16 mm.
Although it was also in other reviews, a hole of about 16.4 mm is missing.
I could not use it for the intended use.
It is a place I want to know if there is a disappointment or such accuracy.
