Need some serious drill bits for metalwork?

This is a 5-pack of YG-1 #21 stub-length drills.

They're made from HSSCo8 cobalt, so they're tough and handle heat well.

Flute length is 1-1/16 inch, overall length 2-1/8 inch.

No coating, just good solid cobalt.

Made in Korea.

These are screw machine length bits, so they're a bit shorter and stiffer than jobbers—great for production work or tight spaces.
