Wera 05104650001 Countersink Set 8 Pc Hss 3 Flute

Product Description

The WERA 05104650001 is an 8-piece countersink set built for chamfering, countersinking, and deburring in metal and wood applications. The set includes six high speed steel (HSS) countersink bits with a 3-flute geometry and a 90-degree included angle, covering head diameters from 1/4 inch to 13/16 inch. A Kraftform quick-release bitholding screwdriver and a universal bit holder are also included, allowing fast bit swaps on the job. All bits feature a 1/4-inch shank diameter and an uncoated finish. The complete kit ships in a plastic storage case for organized transport and bench storage. Licensed trades and skilled DIYers working in metal fabrication, carpentry, or finish work will find this set ready for daily use.

This countersink set is suited for both residential and light commercial applications where consistent, clean countersink profiles are required. The 3-flute design reduces chatter and produces smoother finish cuts compared to single-flute alternatives. The range of six bit sizes allows the technician to match the countersink to a variety of fastener head profiles in a single kit. The included quick-release driver handle speeds up bit changes when working through repetitive fastening tasks across different material thicknesses.

Compatibility

Designed for use with standard 1/4-inch quick-release bitholding drivers and screwdrivers. Countersink bits are suited for chamfering, countersinking, and deburring operations on metal and wood workpieces where a 90-degree seat angle is required.

Installation Notes

Install bits into the quick-release holder before powering the drill or driver. Confirm the workpiece is secured before beginning countersink operations to prevent bit walking. Operate at appropriate speeds for the material being drilled - HSS bits perform best at lower RPM in metal and higher RPM in wood. Inspect bit edges regularly and remove any bits showing visible wear or chipping before continued use.
