TECWERK Countersink DIN 335 C 90° Ø 6.3 mm, HSS Nano, 3‑flute

A precision TECWERK Countersink DIN 335 C 90° Ø 6.3 mm designed for low‑force, high‑quality chamfering across steel, stainless and non‑ferrous materials.

• HSS with nano coating for high wear resistance
• 3‑flute geometry for smooth, quiet cutting
• 90° chamfer for standard deburring and countersinks
• Reduced feed force; faster cycle times up to 30%

Faster cycles through optimised cutting geometry

The combination of HSS substrate and a specialised nano coating reduces friction and improves thermal stability, resulting in up to 60% longer tool life in many applications. The 3‑flute geometry and variable relief were developed to minimise cutting forces and evacuation resistance, which explains the notably smoother running and reduced vibration compared with conventional designs. With a recommended feed in steel (up to 800 N) of 0.15 mm/rev, this countersink shortens processing times while maintaining a consistent chamfer, so production lines achieve better throughput with fewer tool changes.

Consistent finish across a wide range of materials

Built to conform to DIN 335 C, the tool yields clean, repeatable chamfers in steel, stainless steel, aluminium, brass and plastics, reducing secondary finishing. The variable relief and optimised chip space mean burr formation is minimised and surface quality is improved, which is particularly important for components destined for assembly or surface treatment. For workshops seeking dependable results on mixed batches, the controlled cutting action delivers the intended edge geometry without rework.

Practical design for workshop efficiency and clamping security

The cylindrical shank features three clamping flats from Ø 8.3 mm, enabling secure clamping in standard toolholders and quick, repeatable changeovers. Right‑hand cutting and the geometrically tuned chip spaces ensure an extremely quiet run, lowering the risk of chatter and extending service intervals. Overall, the design reduces operator effort due to the lower feed forces required, which benefits both handheld and machine operations by improving ergonomics and reducing process variability.

FAQ

What materials can this countersink handle?
The TECWERK countersink (DIN 335 C, Ø 6.3 mm, SKU 2000865175NW) is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and a range of plastics.

How does the nano coating improve performance?
The nano coating on the TECWERK countersink reduces friction and increases thermal resistance, contributing to extended tool life and more consistent chamfer quality.

What feed rate is recommended for steel applications?
For steel up to 800 N, a feed of approximately 0.15 mm/rev is recommended when using the TECWERK countersink to balance cutting efficiency and surface finish.

Is the shank suitable for standard clamping systems?
Yes; the cylindrical shank with three clamping flats (from nominal Ø 8.3 mm) provides secure clamping in conventional holders and facilitates repeatable tool changes.

How does the 3‑flute design affect finish and noise?
The 3‑flute geometry smooths the cutting action, improving surface finish while delivering an extremely quiet run and reduced vibration compared with some two‑flute alternatives.
