I have used it only once, but I made it well on a thin stainless steel plate.
Since the center drill is thick, after punching down with a little thin drill blade
It is good to work without core.
As the price is reasonable, it seems likely to be able to replace the blade, so will it last long?
The hole opened very beautifully.
It is recommended.
Since the vise shape is for round drilling, it is difficult to pull out the disk-shaped material. Bali will remain magnificent. Because acrylic board melts with heat, it is easy for the vice to get caught and stop rotating. It is safe to fix the board beforehand to the table of the ball version in advance because there is a thing that the material breaks and the acrylic board ruptures at the moment of missing.
