FAQs

What materials can this countersink set be used on?

The Makita D-73455 set is suitable for use on MDF, timber, and general sheet goods.

Can I use this set with an impact driver?

No, this countersink set is specifically designed for use with standard driver drills and should not be used with impact drivers, as this can cause damage.

What sizes are included in the set?

The set includes four sizes: No. 6, 8, 10, and 12, with corresponding drill bit diameters of 3mm, 4mm, 5mm, and 6mm.

How do I adjust the drill bit depth?

You can adjust the drill bit depth using the included hex key. Loosen the setscrew on the side of the countersink body, slide the drill bit to the desired depth, and retighten the setscrew.

What is the shank type?

The set features 1/4" hex shanks, which are compatible with most standard drill chucks.

Does the set allow for screws to be set below the surface?

Yes, the design allows for screws to be set flush or below the surface of the material for a cleaner finish.

How do I maintain the countersink bits?

Keep the bits clean and dry after each use. Periodically check the sharpness of the drill bits and replace them if they become dull. Store them in their original case or a tool organizer.

Troubleshooting

Countersink hole is too large or too small.

Ensure you are using the correct countersink size for your screw. The drill bit size may also need adjustment; use the hex key to set the drill bit depth for your desired pilot hole size.

Drill bit is not cutting effectively.

Check if the drill bit is dull. For best results, ensure the bit is sharp. Also, verify that you are using the appropriate speed setting on your drill for the material.

Bit is slipping in the drill chuck.

Ensure the 1/4" hex shank is fully inserted and the chuck is tightened securely. Use a drill with a keyless chuck for optimal grip.

Countersink is not sitting flush with the surface.

Adjust the depth of the countersink by slightly reducing the drilling pressure or ensuring the drill is not set to an excessively high speed. The drill bit's depth can also be adjusted for shallower or deeper pilot holes.
