Frequently Asked Questions
Is it necessary to drill a pilot hole?
Pilot holes are required if drilling into hardwood, laminate or require an accurately located fastener. They're also suitable if the wood is possible to crack or if appearance is important.
What tool is used for making pilot holes?
A punch is a small, slim tool with a pointed end that permits making a small dent in the work surface. This dent prevents drill bits from slipping when starting the pilot hole. Position the tip of the punch over a pencil mark and then strike the punch lightly with a hammer.
