TECWERK countersink DIN 335 C — HSS, 15 mm, 90° angle, 3 flutes

The TECWERK countersink DIN 335 C is a high‑speed steel conical countersink designed for precise deburring and countersinking of drilled holes in a range of metallic materials.

*HSS construction, compliant with DIN 335 C *90° countersink angle for standard fasteners *Three‑flute design for chatter‑free cutting

Improved process reliability through standardised geometry

The conical cutter conforms to DIN 335 C, ensuring consistent seating for 90° fasteners and predictable material removal. Manufactured from HSS, the tool withstands the thermal and mechanical stresses of routine workshop use while maintaining cutting edge integrity. The three‑flute layout is engineered to deliver a chatter‑free cut, which reduces the need for secondary finishing and lowers scrap rates. Operators benefit from steady feed behaviour even at the typical recommendation of 0.14 mm/rev in steel, helping keep cycle times stable and part quality repeatable.

Easy integration into existing tool setups for versatile use

With a cylindrical shank, the countersink fits standard chucks and toolholders without modification, simplifying tool changeover and inventory management. The geometry is suitable for working on steel, cast iron and non‑ferrous metals, so a single cutter can address multiple operations across production runs. The stated feed suggestion of 0.14 mm/rev for steel is a practical starting point; in softer non‑ferrous materials the same cutter typically runs at higher spindle speed with correspondingly adjusted feed to optimise surface finish and tool life.

Durable finish and reduced rework for workshop efficiency

The tool’s material and flute design contribute to longevity and stable performance under everyday conditions. A clean countersink profile reduces burr formation and improves fastener seating, which in turn decreases rework and inspection effort. For maintenance, periodic sharpening or replacement preserves the defined 90° seating angle and the cutter’s ability to produce consistent chamfers. When paired with appropriate cutting parameters, this countersink supports reliable output and contributes to a smoother production flow.

FAQ

What materials can this countersink process effectively? The TECWERK countersink (DIN 335 C) is suitable for steel, cast iron and non‑ferrous metals, providing reliable deburring and chamfering across these material groups.

What does the three‑flute design achieve? A three‑flute geometry reduces vibration and produces a chatter‑free cut, improving surface finish and lowering the need for secondary finishing on the workpiece.

What feed rate is recommended for steel? The tool specification indicates a practical feed of 0.14 mm/rev in steel at cutting conditions up to 500 N, which balances tool life and surface quality.

Is the shank compatible with standard holders? Yes. The countersink is supplied with a cylindrical shank, designed to fit common chucks and toolholders without additional adaptation.

Does the cutter comply with recognised standards? The geometry follows DIN 335 C for conical countersinks, ensuring standardised seating angles for fasteners.
