TECWERK Countersink DIN 335 C, 90° D 19 mm — HSS, Nano-coated, 3-flute

The TECWERK countersink is a conical countersink designed for precise chamfering and deburring in steel, stainless and heat‑resistant steels, aluminium, brass and plastics.

• HSS construction with Nano coating
• 90° conical geometry for reliable chamfers
• 3‑flute design for smooth, quiet running
• Up to 60% longer tool life

Precision and durability that raise process reliability

The combination of HSS substrate and a specialised Nano coating delivers high wear resistance and increased hot hardness under continuous use. Conforming to DIN 335 C and featuring a 3‑flute geometry with three cutting edges, the tool produces consistent chamfers with reduced axial load. The variable relief and optimised chip space parameters contribute to stable cutting behaviour, which reduces rework and supports predictable production cycles. These design choices translate directly into fewer tool changes and improved overall equipment effectiveness.

Lower force requirements and quieter operation for smoother cycles

Optimised cutting geometry means significantly less feed force is required during countersinking, improving clamping stability and reducing the risk of part distortion. The tool’s geometry enables an extremely quiet run, making it suitable for close‑tolerance assemblies and environments where vibration must be minimised. For steel applications up to the specified resistance, a typical feed is 0.2 mm/rev under a cutting resistance of up to 800 N, delivering clean chamfers more quickly—claims of up to 30% faster countersinking are supported by the reduced friction and optimised chip evacuation.

Broad material compatibility with secure clamping

Designed for a wide range of materials, the countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and plastics, offering the flexibility needed in mixed‑material production runs. A shank with three flats from nominal Ø 8.3 mm improves axial and radial clamping security in most toolholders and collets, reducing slip and runout. The right‑hand cutting orientation and conical 90° angle make it well suited to standard chamfer specifications and deburring tasks across workshop and industrial applications.

Predictable lifetime and straightforward integration

Specially tuned chip space geometry and the Nano surface finish extend service intervals, with up to 60% higher tool life reported versus comparable uncoated designs. The stable cutting behaviour reduces unexpected downtime and simplifies process documentation for quality control. Integration into existing workflows is straightforward due to the DIN 335 C standard form and common shank design; the result is a countersinking solution that balances performance, durability, and repeatability without extensive parameter changes.
