Product Details
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.
