Bosch Professional Wood Spiral Drill Bit with Countersink 3 mm

The Bosch Professional Wood Spiral Drill Bit with Countersink 3.0 mm is a single-piece accessory designed for woodworking. Performing pilot drilling and recess cutting in one operation improves efficiency when preparing materials for hardware. A 3 mm cutting diameter makes the tool well-suited for small-scale joinery. Typical applications include solid hardwood, softwood, chipboard, and plywood. Combining these two functions provides a clean entry point while shaping the timber for flush screw seating. This format is practical for repetitive tasks where switching tools slows down assembly.

Powering this accessory requires a standard electric drill, driver, or dedicated drill stand. The design relies on the user feeding the bit straight into the workpiece to achieve a neat recess. Removing the need to swap between a standard spiral cutter and a separate deburring tool keeps projects moving steadily. The main flute bores into the timber while the countersink simultaneously shapes the surface. Correct alignment ensures the resulting hole matches the intended hardware. Straightforward operation supports accurate results across various wood-based projects.

• Solid tool steel construction maintains sharpness during repeated use on timber and manufactured boards.
• 60 mm overall length provides sufficient reach for standard hinge and bracket installations.
• Integrated 90° point angle accurately matches the profile of common flat-head screws.
• Five independent cutting edges on the countersink collar reduce material tear-out around the rim.
• 16 mm shank diameter dictates the chuck capacity required for secure tool clamping.
