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.
For metal processing

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.

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.

I do not know because it is only used a little yet, but I think reasonably well.
Drilling of aluminum and wood

As others have said, almost all diameters do not come out of the center and almost all axes are crazy and tilted, so it can not be used properly because it is shaken by Brunmble. If you do not use it well by suppressing vibration, it breaks. Those with small diameters will break easily unless they are careful. The size is almost aligned at this price and the thick diameter is especially useful because the step drill is particularly useful ★ I made it two.
