Clean and Professional Screw Finishing
Do your customers want to hide screw heads for a cleaner and more professional finish? Hongniu Tool provides an effective solution.
This Carbide Countersink Drill Bit is designed to create tapered holes so that screw heads can sit flush inside the wood surface.
The result is a smooth, flat finish that can be further covered with wood plugs or filler for a high-quality appearance.
The tool uses an 8mm round shank for universal compatibility. Total length is 55mm.
Two Countersink Sizes for Different Applications
This Carbide Countersink Drill Bit is available in two countersink diameters:
- 8mm countersink
- 10mm countersink
The center drill is available in five diameters:
2.8mm, 3.0mm, 3.2mm, 3.5mm, and 4.0mm.
All cutting edges are made from carbide material, ensuring sharp cutting performance and long service life.
Model combinations:
- 2.8×8mm, 3.0×8mm, 3.2×8mm, 3.5×8mm, 4.0×8mm
- 2.8×10mm, 3.0×10mm, 3.2×10mm, 3.5×10mm, 4.0×10mm
Simple Operation and Reliable Performance
Users can select the appropriate size based on screw specifications. The center drill size should match the screw diameter, while the countersink size should match the screw head size.
For best results, insert the tool into a hand drill and operate at a steady speed. Apply light pressure and allow the drill to cut gradually to achieve a smooth and clean tapered hole.
This Carbide Countersink Drill Bit is designed for easy operation, stable performance, and consistent finishing results in woodworking applications.
