The Irwin Cobalt M-42 Metal Index 29 Piece Drill Bit Set is made of M-42 8% cobalt high-speed steel. This hardened material helps to extend the cutting edge life and maintains the cutting life after resharpening. It includes drills that are extra hard and ensure greater wear. The 135-degree split point tip conveniently starts on contact and cuts with less force.

It also has a Tap and Drill selection chart that you can use for reference. The cartridges are easily removable and can be carried to the work location individually.
