The Blue Spot Tools 99 PCE 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 135Â° 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 centre punch when starting the hole. The set is supplied in a metal case for easy storage and transportation.
