Prepare Neater Screw Recesses in Wood
Drill a pilot hole and create a recess for the screw head with one adjustable tool. Choose the pilot size you need, or get all five sizes for different woodworking projects.
Adjust Your Setup for the Job
The adjustable stop lets you set the working length before drilling. Use the included adjustment tools to prepare the bit for your workpiece, then test the setting on a scrap piece of the same material.
Adjustment Tools Included with Every Single Bit
Each single-bit option comes with one complete countersink bit, one open-end wrench and one hex key. You can adjust the setup using the supplied tools.
Disconnect the drill from power before making adjustments, and check that all adjustable parts are securely tightened before use.
Pilot Hole and Screw-Head Recess in One Tool
The center drill prepares the pilot hole while the surrounding cutter forms the recess. All options have an 8 mm countersink diameter, with five center drill diameters available.
Select the pilot diameter to suit your screw and wood type. Check the screw-head fit and recess depth before working on the finished piece.
One Shank Size Across All Options
Every size has an 8 mm round shank and an overall length of approximately 60 mm. Check that your drill chuck accepts an 8 mm round shank before ordering.
Use rotary drilling mode. The round shank does not fit directly into a standard 1/4-inch hex quick-release holder.
Choose One Size or the Complete Five-Size Set
Choose a single bit for a specific task, or select the five-piece set to keep all available pilot diameters on hand.
- Single bit: One complete bit in your selected pilot size, plus one open-end wrench and one hex key.
- Five-piece set: Five complete bits, with one each in 2.8, 3.0, 3.2, 3.5 and 4.0 mm pilot sizes. Adjustment tools are included.
- All options: 8 mm countersink diameter and 8 mm shank diameter.
