Countersink bit Wolfcraft WF4373000 16 mm, hex shank, ejector

The Wolfcraft WF4373000 countersink bit with a 16 mm cutter diameter is designed for creating clean chamfers and countersinks in wood and similar materials. The bit has a hex shank that fits quick‑change holders and standard chucks, and an integrated ejector mechanism that helps remove chips and facilitates fast bit changes. It is intended for use with handheld drills and drill presses in woodworking and joinery applications where precise edge finishing or screw head seating is required.

Advantages

The tool combines a 16 mm cutting diameter with a hexagonal shank for secure mounting and torque transfer. The ejector mechanism reduces downtime by making chip removal and replacement quicker. The geometry of the cutter is optimized for wood and comparable materials to produce uniform chamfers and consistent countersinks. Its compatible shank type enables use in a wide range of drilling tools, increasing versatility on the job.

Suitable for

• Creating chamfers and bevelled edges in solid wood and plywood
• Drilling countersinks for screw heads in furniture assembly and joinery
• Use with handheld drills and drill presses for finishing tasks
• Carpentry and on‑site woodworking repairs where quick bit changes are needed

Key specifications

• Cutter diameter: 16 mm
• Shank type: hexagonal (6 mm compatible)
• Material suitability: wood and similar materials
• Ejector mechanism for chip removal and faster bit changes
• Compatible with handheld drills and drill presses

How to use

Secure the hex shank in the drill chuck or quick‑change holder, ensuring the bit is tightened properly. Set the drill or press to an appropriate speed for the wood type and apply steady pressure while advancing the cutter to the required depth to form the chamfer or countersink. Use the ejector mechanism to clear chips and retract the cutter; check the result and adjust depth or speed if necessary. Follow standard safety practices: clamp workpieces, wear eye protection, and avoid excessive feed rates that could cause tear‑out.

Usage recommendations

For best results, use moderate rotational speed for softwoods and lower speeds for hardwoods, and perform test cuts on scrap material to set the correct depth. Keep the cutter clean of resin and pitch build‑up and replace the bit when wear affects the quality of the chamfer or countersink.
