ANSI High Speed Steel HSS Drill Bits Long Type Twist Drill Bits For Metal Bright Finished
HSS 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.
