Because there are a lot of screw processed into aluminum material, we used an inexpensive this product.
Perhaps because of changing the drill chuck to those of high-precision, drill has made accurate drilling without blurring at all.

An attempt was made to drilling to 2mm SUS plate in the drill teeth of a hand-held electric drill + titanium coated with amateur DIY, but it takes an hour, yet the position of the hole is gradually I have also shifted 4mm.
Half to give up, I tried to use to obtain the product of stainless steel only, not less than five minutes, we were able drilling To crispy. It seems to be baffled.
