Machined cutting groove
Precision ground hex shank
Wood Drill Bits-Flat Bits
Grooved cutting edges of the flat bits cut wood instead of scraping it away, resulting in reduced heat built-up and cutting edges that stay sharper longer.
The flat bits hav double positive spurs, which can scribe the hole before the chips are made, providing a cleaner hole inside and reduce vibration.
Grooved hex shank prevents spinning in drill chuck or in bit extension.
Drill bits manufacture in China supply the flat bits with low cost.
