TECWERK Cross‑Hole Countersink Set – HSS‑Co, 90° Countersinks, Cylindrical Shank

A TECWERK cross‑hole countersink set designed for efficient, chatter‑free deburring of drilled holes in long‑chipping, soft materials

• HSS‑Co cutting material for extended life
• 90° countersink for standard chamfers
• Oblique chip ejection prevents tool damage
• Supplied in a robust plastic case

High‑performance deburring for reliable production

The set combines HSS‑Co cutting material with a 90° countersink geometry to deliver a shearing action that reduces vibration and tool chatter. This results in faster, more consistent deburring and cleaner chamfers after drilling. The cylindrical shank enables secure clamping in standard toolholders, while the optimised cutting geometry produces short, predictable results that simplify downstream assembly and finishing. The design focuses on measurable performance: improved surface finish and reduced rework time.

Chip evacuation that protects the countersink and workpiece

An oblique through‑hole in each countersink channels swarf away from the cutting faces toward the shank, so chips cannot rebound and damage the tool. This chip ejection method maintains cutting integrity during repeated use and reduces the risk of fretting or scratching the chamfer edge. Particularly suited to soft, long‑chipping materials, the set is effective on typical workshop metals that produce continuous chips, ensuring dependable evacuation and longer tool life.

Practical set‑up and storage for workshop efficiency

Delivered as a compact, 4‑piece set in a protective plastic case, the tools are organised for quick selection and safe storage. The case keeps the countersinks protected during transport and on the bench, cutting downtime for searches or accidental damage. The combination of durable cutting material and clear storage reduces tool consumption and supports a lean workshop routine, making the set a pragmatic choice for production environments and trade workshops seeking dependable tooling without complex maintenance.

FAQ

What materials are best suited to these countersinks?
The TECWERK cross‑hole countersink set is particularly suited to soft, long‑chipping materials, where the oblique chip ejection keeps swarf clear and the HSS‑Co edges perform reliably.

How many pieces are included in the set and how are they supplied?
The delivery contains four countersinks supplied in a plastic case for secure storage and easy selection.

Why does the countersink have an oblique hole?
The oblique through‑hole directs chips towards the shank so that expelled swarf cannot damage the cutting edges, ensuring longer tool life and consistent chamfer quality.

Is the 90° angle suitable for common chamfering tasks?
Yes, the 90° countersink angle provides a standard chamfer profile commonly required for deburring and preparing holes for fasteners.

Can these countersinks be used in handheld drills?
The tools have a cylindrical shank suitable for standard chucks and holders; secure clamping is recommended for safe, chatter‑free operation.
