THE FLEXIBLE ADDITION TO EXISTING WOOD TWIST DRILLS.
The purchase of countersink drills does not always seem economical if connections with screws are not made too often. In this case, we recommend that you resort to slip-on countersinks. With these, the wood twist drills available in every woodworking shop are upgraded to make a through hole and countersink for a screw in one go. The countersinks are usually attached to the drill with a grub screw. This also allows the drilling depth to be adjusted. However, they cannot be used in metal materials because the forces that occur there are too high for the fastening.
In order to be prepared for all cases, you can use our countersink sets, which are also available with corresponding wood spiral drills if desired.
