Adjustable Depth-Stop Countersink Sets

Prepare pilot holes and screw seats with a matched countersink assembly. These sets offer adjustable depth control for suitable wood and board fastening work.

✅ Repeat a chosen countersink depth - The stop helps limit travel after adjustment.

✅ Match the pilot hole to the screw - Different bit configurations provide several drilling sizes.

✅ Help reduce surface marking - The plastic collar separates the stop contact from the work surface.

✅ Use a compatible hex holder - The shank fits a matching drill or driver arrangement.

Choose the Set Configuration for the Fasteners

The A, B and C selections and normal/Second Switching labels identify separate set configurations. Match the actual drill sizes and countersink profiles to the screws before choosing.

Set drill projection and stop depth, then test on spare material. Keep the workpiece secure and use the speed appropriate to the cutter and material.
