Straight Shank Twist Drill Bits

The Straight Shank Twist Drill Bits have sharp spiral grooves that provide neat, smooth cuts. The spiral groove ensures rapid heat dissipation of the drill bit while cutting, reducing damage to the drill bit caused by high temperatures. It can also allow cutting debris to be quickly exported to prevent debris from getting stuck in the cutting hole and hindering the cutting progress.
