Should I drill pilot holes?

Pilot holes are necessary if you’re drilling into hardwood, laminate, or need a precisely located fastener. They’re also recommended if the wood is likely to crack, or if appearance is important. You can skip the pilot holes when doing a rough build with softwood where appearance isn’t important.

What tool makes pilot holes?

A punch is a small, slender tool with a pointed end that allows you to create a small indentation in the work surface. This indentation will help keep your drill bit from slipping when starting the pilot hole. Position the tip of the punch over your pencil mark, and then strike the punch gently with a hammer.

How do I choose the right size drill bit?

The diameter of the hole you drill should be slightly smaller than the diameter of the screw. So, for example, if you’re using a 3.5 mm screw, use a drill bit with a diameter of 3 mm. If you’re using wall anchors as well as screws, the drill bit and anchors should have the same diameter.

How big should pilot holes be in wood?





For most hardwoods, the pilot hole should be at least as large as the screw’s minor diameter. If the screw has deep threads, or the wood is very hard, the pilot hole should be another 1/64-in. larger than the minor diameter. For softer woods, the pilot hole can be 1/64-in.

Why is my wood splitting when drilling?



Much like knots in the wood, they are separated by a thin layer of sap, which is more brittle than a piece of board with no knots or pronounced grains. Also, because the drill is rotating into the wood, it will pull apart the two separate sides of the grain slightly, causing it to split along the board’s length.
