Extra Long HSS Drill Bits Circular Shape Flexible 135° Point Cobalt twist drill bits

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.

Features

1.Cobalt drill bits are more expensive than other drill bits, but if you regularly drill through metal, they are a

good investment since they tend to last longer.
2.No center punch is needed—the aggressive 135° Quick-Cut points are self-centering and penetrate quickly

with lesspressure. Will not "walk" or "wander".
3.Precision ground point, flutes, body, clearance and drill 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.DIN 338 jobber series drill bits are ideal for many trade and industrial projects.
