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.

diameter for the ultimate in accuracy and performance.
4.Ground flutes provide fast chip removal to maximize accuracy and
efficiency along the full working surface of the bit.
5.Short length drill bit offers rigidity to reduce tool deflection
and breakage. |
