12pc 'F' (.2570

Machinists and metalworkers, listen up!

This is a set of 12 high-quality cobalt jobber length drill bits from Rocky Mountain Twist.

They're the 'F' size, which is exactly 0.2570 inches in diameter.

They're made from M42 HSS-Co8% cobalt steel, so they're perfect for drilling tough materials like stainless steel and hard alloys.

Each bit has a 135-degree split point, which helps prevent walking and requires less pressure to start the hole.

They have a 30-degree helix angle, right-hand cut, and are uncoated.

The overall length is 4.125 inches, with a flute length of 2.875 inches.

The shank diameter is the same as the drill diameter.

And the best part?

They're made in the USA.

This 12-pack (part 95006405) is a serious investment in quality tooling.
