Decent drills for the price point.

Moderate quality, moderate price
Comparing these M35 bits against M42 bits, drilling through 16 gauge stainless: I could get 8 holes with the M42 bits before needing resharpening, but only 2 holes with these M35 bits. However, after resharpening with a diamond wheel, the M35 bits became useable again. I guess, these bits are worthwhile if you are willing to resharpen them or don't intend to use them a lot on very hard metals. I also felt that their initial sharpness was not quite up to expectations.
