8mm M42 8% Cobalt Drill Bits (1 Pack), Metric Titanium Twist Drill Bits for Hard Metal, Stainless Steel and Cast Iron
Excellent little kit. Building my first PC and this has been a huge help. Highly recommend. It’s not super high rpm even at the top setting but still beats manually turning. Relatively low torque so you don’t have to worry about over-tightening. The extending manual driver is nice too. A++
