For pilot hole of M5 tap
From Japan

Because there are many screw processing to aluminum material, I tried using this inexpensive product. Due to changing the drill chuck to high precision, accurate drilling is done without drill blur at all.

Drill a hole in SUS plate
From Japan
On 2013-11-18 21:32:46
I tried drilling on a 2 mm SUS plate with a drill tooth on a hand held electric drill + titanium coat with amateur DIY, but it took 1 hour, and gradually the position of the hole gradually deviated by 4 mm. Half a half, I got this product dedicated to stainless steel, when using it, it took less than 5 minutes, and it was possible to drill up quickly. It seems that the fox has pinched it. You can do a good job with good tools. Please try.

Continued, quality is of course, if you can do a little more price, I think that you will not mind other companies' prices on the net.
