Frequently asked questions
What tool do I need to use this drill bit?
A round-shank bit must be held in a chuck, so use it with a handheld rotary tool, a mini drill or a small drill press. Run it at moderate speed with light pressure, because a 1 mm bit can snap if forced.
Is 1 mm suitable for all component leads?
A 1 mm hole suits many small through-hole resistors and diodes, but connectors and thicker leads need larger holes. Match the bit to the lead diameter of your component, allowing a small clearance, and use the 0.5 mm or 0.8 mm sizes for finer leads.
