The FAMAG 180° countersink attachment turns any 13 mm-shank auger bit into a combined drill-and-countersink tool. Simply slide the attachment onto your bit, clamp in place, and drill: you’ll produce a perfectly sized hole with a clean 90° chamfer in a single pass. Recommended for softwoods, this accessory streamlines woodworking by eliminating a separate countersinking step

🎯 Key Benefits

• Integrated Operation: Drill pilot hole and countersink in one step.

• Time Savings: Eliminates tool changes—boosts workshop efficiency.

• Consistent Chamfers: Precision-ground cutter ensures repeatable 90° bevels.

• Durable Construction: Tool-steel body resists wear under repeated use.

⚙️ Application Tips

1. Install Securely: Align the countersink cutter over the bit’s flute, then tighten the set screw firmly.

2. Pilot Hole First: For best results, pre-drill a small starter hole to guide the auger bit.

3. Optimal Speed: Run at 800–1 200 rpm in softwood for smooth chips and minimal tear-out.

4. Uniform Pressure: Let the tool’s weight advance the cut—avoid forcing to prevent chatter.

5. Maintenance: Clean off wood debris after each use and lightly oil the steel surfaces to prevent rust.
