FAQ:

Q: How do you drill a countersink?

A: To drill a countersink, place the countersink bit in your drill and push down lightly on the pilot hole. For those who prefer a hands on approach, a hand held countersink tool is also available. Drill down a little at a time until your desired depth.

Q: What are the best drill bits for wood?

A: The DEWALT DW1361 drill bits are the best bits for wood because they are very effective and they are also long-lasting. The set includes 21 bits; they range in size from 1/16th inch to 1/2 inch so they can be used to drill holes for your most common woodwork projects and even some that may not be considered as common.

Q: What size bit do you use to countersink?

A: The size of your countersink bit should match the size of the screw you plan to use. The number size of the screw is typically on the packaging. #6, 8 and 10 are most common. Make sure the screw has a flat head with a conical shape underneath.

Q: How to use a countersink bit?

A: Mark the hole position on the wood piece. Choose the correct countersink bit size for the screws. Adjust the countersink bit height to match the screw length. Insert the bit into the chuck of the drill. Drill the countersink hole at the marked spot. Start the drill off fast to penetrate the wood,then slow down the speed when making the countersink hole. Test the fit with the screw,making sure the head rests below the surface of the wood. Cover screw head with wood filler or wood plug,if desired.
