Processing of laboratory instruments

It is very convenient that a step drill becomes a set for a straight drill. The price is reasonable and very useful. I thought that I wanted it for individuals not for work, but it is regrettable that handling is over. I confirmed the substitute, but I am a bit disappointed with a set of straight drills.
For drilling work

It is still unused, but it was cheap so I think I can get original just by being able to use it once or twice.

3 mm or less is not usable. It broke soon.
Even though titanium coating is applied, I think it is a matter of the material before that.
I do not use it because I do not use 3 mm or more.
As a result, I used a regular steel drill.
For professional use it is not usable, it is for amateur DYI to the last.
Especially, it is not suitable for torquey impact and drill driver.

As of now I can use it normally. It is relatively inexpensive, has step bits, it is useful.

Purchased for metalworking finish. Especially the step bit is a hexagonal axis, it is easy to detach and increase work efficiency. It is useful for deburring of the cut surface.

I think that performance is sufficient for price. It is a compact, portable, good price and it does not hesitate to buy again even if it breaks.

It was good to use it well. I am using it for punching holes in tap pins.
When creating the test tool

Even though each size is aligned, Takeko naka is still a big success!
When preparing pilot holes such as rafters

Used by attaching to the impact driver. The axis of the center is slightly misaligned. While pushing it will shake it.

It is good that the step bit is set.
