1. Description
STARRY 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.
