Frequently Asked Questions

What is the RUKO TOOLS tube and sheet drill set used for?

The set includes three cobalt drill bits ranging from 3 mm to 30.5 mm, each with a 118° point angle. The bits are not impact rated. The manufacturer part number is 101020ERO. Cobalt construction provides heat resistance for drilling stainless steel and other hard metals.
