Countersink drill bit KWB 704510 2 cm diameter 1 pc

This KWB countersink drill bit (MPN 704510, EAN 4009317045106) is designed for creating conical recesses for screw heads in wood and non-ferrous metals. The tool features a five-edged tip for precise machining, an 8 mm cylindrical shank for stable mounting and a 50 mm overall length that balances handling and reach. Constructed from carbon steel with a black oxide corrosion-resistant finish, the countersink is available in multiple head diameters and intended to deliver durable, accurate results for woodworking and metalworking tasks.

Advantages

The five-edged tip provides improved precision when producing flush countersinks. A carbon steel body with black oxide finish increases resistance to corrosion and wear. The 8 mm cylindrical shank ensures stable fitting in standard chucks, and the 50 mm overall length offers a compromise between control and accessibility. Multiple head diameter options allow selection of the appropriate size for different screw heads and materials.

Suitable for

• Creating flush screw recesses in wood
• Countersinking in non-ferrous metals (e.g., aluminum, brass)
• Carpentry and furniture assembly
• Light metalworking and maintenance tasks

How to use

Secure the countersink in the drill chuck using the 8 mm cylindrical shank. Select the appropriate head diameter for the screw head and material. Drill a pilot hole if required, then apply steady pressure at low to medium speed to create the conical recess. Withdraw the tool periodically to clear chips and avoid overheating. After use, clean chips from the tip and store the bit dry to preserve the black oxide finish.

Usage recommendations

Use low to medium drilling speeds for non-ferrous metals and medium speeds for wood; avoid excessive feed force to maintain precision and extend tool life.
