Frequently asked questions
What tool do I need to use these bits?
Use a rotary tool or a small PCB drill that can hold small-diameter shanks. These bits are fragile at this size, so use light pressure and a steady speed.
Are the bits suitable for drilling through-hole PCB pads?
Yes, the 0.7 to 1.4 mm sizes are commonly used for small through-hole component leads on PCBs. Choose the size closest to your lead diameter plus a small clearance.
