The Clarke CHT931 99-Piece Cobalt Drill Set is manufactured from M35 steel for increased speed and effective cutting, even at high temperatures. Each drill bit is finished with a 135° split point, ideal for the cutting of sheet materials, reducing the chance of the bit slipping during use, the 5% cobalt content also makes the drills better at drilling in harder materials.

We strongly advise that when drilling in steel and stainless steel, that you use a cutting fluid and center punch when starting the hole.
