TECWERK countersink 75° Ø12.4 mm (HSS, 3‑flute, 8 mm shank)

A TECWERK countersink 75° Ø12.4 mm engineered for burr‑free chamfering, deburring and countersinking across steel and non‑ferrous materials

• HSS solid construction, Form C, 3 cutting edges
• 75° countersink angle for standard chamfers
• 8 mm cylindrical shank for stable clamping

Precise, burr‑free chamfering for workshop efficiency

The high‑speed steel design with Form C geometry and 3‑flute cutting ensures a clean cut and reduced burr formation when countersinking or deburring. The combination of a 75° cutting angle and right‑hand cutting action suits typical seating and chamfer requirements, delivering repeatable edge quality. Because the tool is optimised for low cutting speed, heat generation is limited and surface finish is improved, which reduces rework and increases throughput in production and workshop environments.

Stable clamping and predictable feed for consistent holes

A cylindrical shank with a diameter of 8 mm provides a secure grip in standard holders and chucks, reducing runout and vibration. The tool geometry supports a defined feed: in steel, under a cutting force of up to 500 N, the recommended feed is 0.14 mm/rev, enabling controlled material removal and reproducible chamfers. The robust HSS substrate maintains edge stability during operation, so indexable or frequent replacements are minimised and process reliability is increased.

Practical application and handling for reliable results

Designed for general workshop use, the tool is suitable for countersinking, chamfering and deburring of steel, cast and non‑ferrous metals such as brass and aluminium. Right‑hand cutting offers conventional machining behaviour and straightforward programming where applicable. For best performance, operate at lower cutting speeds with steady feeds and secure clamping; this reduces the risk of chatter and preserves the cutting edge, prolonging tool life and maintaining consistent component quality.
