Frequently asked questions
Will this bit fit my CNC router collet?
The 3.175 mm shank requires a 1/8 inch (3.175 mm) collet. Check that your spindle or router collet matches this shank size before installing the bit.
What should I watch for when drilling PCBs with a 2.0 mm carbide bit?
A 2.0 mm bit is very thin and breaks easily. Use light pecking passes, a suitable spindle speed, and firmly clamped PCB material, and avoid any side load on the bit.
