TECWERK 120° Countersink Ø25 mm — HSS, 3-flute, 10 mm shank

The TECWERK 120° Countersink Ø25 mm is a high-speed steel conical countersink designed for burr-free countersinking, deburring and spot-facing in steels, cast components and non-ferrous alloys.

• HSS ground, 3-flute geometry for smooth cutting
• 120° countersink angle for standard chamfers
• 25 mm diameter for larger chamfering tasks
• 10 mm cylindrical shank for secure toolholding

Faster, cleaner chamfering with industrial-grade materials

This conical cutter combines a high-speed steel (HSS) construction with a 3-flute geometry to deliver consistent, burr-free chamfers and deburring results. The hardened tool steel provides abrasion resistance and predictable tool life when used under recommended conditions, while the triple-flute design evens out cutting forces to reduce chatter. Such properties make the cutter particularly suitable for workshop environments where repeatable finishing quality on mixed batches matters.

Optimised for low cutting speeds and reliable feeds

Engineered for effective performance at low cutting speed, the tool provides best results when the spindle speed is moderated and feed rates are controlled. The geometry is specified with a recommended feed in steel up to 0.2 mm/rev, which balances material removal and surface finish to minimise workpiece damage. The right-hand cutting direction and Form C profile ensure stable chip formation and predictable behaviour in through-hole countersinking and spot-facing operations.

Secure clamping and compatibility with common toolholders

The cylindrical 10 mm shank offers reliable engagement in standard chucks and collets, reducing runout and improving concentricity for larger-diameter operations. This straightforward shank design simplifies tool changes and maintains alignment in production or maintenance settings. The robust mounting coupled with the cutter’s geometry supports consistent axial guidance during chamfering, contributing to uniform chamfer depths and clean edges.

Suitable applications and recommended materials

Designed for burr removal, chamfering and spot-facing, the cutter achieves best results on steel, cast iron and non-ferrous metals such as aluminium and brass. The tool is described as ideal for producing clean, rattle-free countersinks and for finishing operations where surface integrity is crucial. For precision workshop use, the combination of 25 mm diameter and the 120° angle suits standard countersink profiles used in assembly and repair tasks.

FAQ

What materials is this countersink suitable for?
The TECWERK 120° Countersink is suitable for steel, cast components and non-ferrous/light metals such as aluminium and brass, delivering burr-free chamfers and clean finishes.

What shank size is required for clamping?
A 10 mm cylindrical shank is specified; the countersink fits standard chucks and collets designed for this shank diameter.

What is the recommended feed rate in steel?
For reliable results in steel, use a feed up to 0.2 mm/rev as indicated for controlled chip formation and a good surface finish.

Which spindle speeds produce the best results?
Best results are achieved at lower cutting speeds; the cutter is optimised for moderate spindle speeds that match the material and feed recommendation.

Is the geometry suitable for preventing chatter during countersinking?
Yes, the 3-flute Form C geometry and HSS construction are designed to reduce vibration and enable rattle-free countersinking operations.
