Review on Screw-Taper Point: Unleashing the Power of Fuller 20100187! by Elijah Balzarini

I use Dewalts drill bits from a hardware store and I have to say they suck compared to that brand. I use this specific size for professional drilling of cabinet hardware and after drilling at least 1000 holes the drill bit is still as sharp as when I bought it! Dewalt and other cheap Chinese brands will tarnish and burn after a few punctures, and that's if they don't break and bend first!
