Review on Timberline 670 160 🔧 Forstner Shank Set of 16 Pieces by Christopher Clearfield

Arrived quickly. I used a few different diameters to make a bottle cage out of a 2x4 piece. The holes are amazingly clean on both the sides and bottom, and the tip pilot hole is very shallow, resulting in a really nice finished piece. And the hexagonal shank ensures a really secure grip between drill and bit. I used a hand drill and had good depth control. The bit did not "run away" into the wood.
