This Cobalt Drill Set is manufactured from M35 steel for increased speed and effective cutting, even at high temperatures.
The drill bits are finished with a 135° split point, which is ideal for the cutting of sheet materials, and reduces the chance of the bit slipping during use, the 5% cobalt content also makes the drills better at drilling in harder materials.
As normal when drilling in steel and stainless steel we recommend that you use a cutting fluid and center punch when starting the hole.
The set is supplied in a metal case for easy storage and transportation.
