25mm Countersink 90° HSS Nano Coated 3-Flute Three-Point Shank, For Steel Aluminium Brass Plastics, Right-Hand - TECWERK

Take advantage of the combination of HSS construction, a nano coating and a 90° geometry for fast, durable chamfering; the three‑flute design reduces feed force and ensures a very smooth run. Order the TECWERK countersink directly via Metav Werkzeuge or request advice from our consultants.

TECWERK countersink DIN 335 C – 90° (25 mm), HSS Nano, 3‑flute

The TECWERK countersink DIN 335 C is a precision 90° countersink designed for optimised chamfering and deburring across steel, stainless and heat‑resistant steels, aluminium, brass and plastics.

• HSS with nano coating for high wear resistance
• 90° geometry for optimised chamfering
• Three‑flute design for quiet, smooth running
• Shank with three clamping flats from Ø 8.3 mm

Faster, cleaner chamfering for continuous production

The combination of HSS substrate and a specialised nano coating reduces friction and heat build‑up during machining, which translates into reduced feed force and more consistent finishes. With a 90° cutting angle and a 3‑flute layout, the tool delivers controlled chip formation and a substantially improved surface on chamfers and countersinks. Measurable productivity gains are reported: up to 30% faster countersinking under comparable conditions, making this countersink a practical choice where cycle time and repeatability matter.

Designed for durable performance and stable running

A variable relief and specially developed optimised chip space parameters increase thermal stability and cut down wear, leading to up to 60% longer tool life in demanding applications. The right‑hand cutting geometry ensures reliable chip evacuation, while the flute geometry and balance produce an extremely quiet run, reducing vibration and improving tool life on high‑precision machines. These technical refinements mean less downtime for tool changes and steadier throughput in series production.

Clear material compatibility and recommended operating range

The tool is suitable for machining steel, stainless and heat‑resistant steels, aluminium, brass and various plastics; this versatility reduces the need for multiple specialised countersinks on mixed work orders. For guidance on cutting parameters, the recommended feed in steel up to 800 N is 0.2 mm/rev, which balances chip load and surface quality for most applications. The tool’s geometry supports conservative feeds at higher forces, enabling operators to prioritise finish or throughput as required.

Practical shank design and workshop integration

A shaft equipped with a shank with three clamping flats from nominal Ø 8.3 mm ensures secure clamping in standard toolholders and collets, eliminating slippage during operation and simplifying changeover. The three‑flute format and nano surface finish also reduce the propensity for built‑up edge when working with soft alloys, while the overall design supports straightforward inclusion in CNC and manual machining processes. For contract manufacturers and workshop supervisors, the countersink combines predictable performance with low handling complexity.
