Countersink bit Wolfcraft WF4370000 — 8 mm cutting diameter, 6‑point hex shank with ejector

Wolfcraft countersink bit WF4370000 has an 8 mm cutting diameter and a 6-point hexagonal shank with an integrated ejector. It is made for creating clean countersinks and chamfers in wood, plastics and soft metals. The hex shank allows fast, secure mounting in drills and drivers that accept hex bits, while the ejector simplifies removal of the bit from the chuck or holder after use. The design supports controlled depth and repeatable results for small joinery and fitting tasks.

Advantages

This countersink bit provides a precise 8 mm cutting diameter suitable for common screw heads and rebates. The 6-point hex shank offers improved torque transfer and quick bit changes without additional adapters. The ejector mechanism reduces effort when removing the bit from the tool and helps maintain workflow efficiency. Its geometry is suitable for producing clean, burr-free countersinks and chamfers in a range of materials.

Suitable for (tasks / use cases)

• Furniture assembly and screw countersinking
• Hinge and fitting installation
• Precision joinery and cabinetry
• Deburring and chamfering of plastic parts
• Light fabrication in soft metals such as aluminium

Key specifications

• Cutting diameter: 8 mm
• Shank type: 6-point hexagonal shank
• Ejector: integrated ejector for easy removal
• Material compatibility: wood, plastics, soft metals
• Typical use: countersinking and chamfering

How to use

Secure the bit in a drill or driver that accepts a 6-point hex shank. Mark the screw or hole center and clamp the workpiece to prevent movement. Start at low speed to establish the countersink, then increase speed as appropriate for the material while applying steady axial pressure. Use short, controlled passes to avoid overheating or tear-out. After finishing, release the tool and use the ejector action to withdraw the bit from the chuck or holder.

Usage recommendations

Use appropriate clamping and a backing piece when working near edges to reduce splintering in wood and plastic. Select drill speeds suitable to the material: lower speeds for soft metals and plastics, moderate to higher speeds for clean cuts in wood. Inspect the cutting edges before use and replace the bit if worn to ensure consistent countersink quality.
