Amber Finished Cobalt Drill Bit , Parallel Shank Hss Twist Drill Bit

STARRY HSS Twist Drill bits are cutting tools used to create cylindrical holes, almost always of circular cross-section. Bits are held in a tool called a drill, which rotates them and provides torque and axial force to create the hole. Specialized bits are also available for non-cylindrical-shaped holes.
