TECWERK Countersink DIN 335C Ø 31 mm — HSS, nano-coated, 3‑flute

The TECWERK countersink DIN 335C Ø 31 mm is designed for fast, stable 90° countersinking across a wide range of metals and plastics.

• Nano-coated HSS for enhanced wear resistance
• 3-flute geometry for smooth running and finish
• Reduced feed force for lower spindle load
• Optimised chip groove for longer tool life

Faster cycles and more uptime

The HSS substrate combined with a specialised nano-coating and optimised chip geometry delivers measurable productivity gains: cutting forces are noticeably lower, enabling up to 30% faster countersinking in many setups while maintaining surface quality. Reduced feed force translates into less axial load on the spindle and fixtures, which helps to shorten cycle times and reduces the frequency of tool changes. For production environments seeking reliability under repeat load, this configuration supports consistent results with fewer interruptions.

Suitable for multiple materials with reliable finish

Engineered to handle a broad material spectrum—including steel, stainless and heat-resistant steels, aluminium, brass and various plastics—the tool’s variable relief and refined flute design improve chip evacuation and minimise burring. The result is a cleaner, more reproducible chamfer and fewer secondary operations. Because the geometry favours stable chip formation, operators can expect improved surface finish and dimensional accuracy even when moving between different workpiece materials.

Secure clamping and clear machining guidance

Compliance with DIN 335C assures a standardised 90° cone form; the three-flatted shank from nominal Ø 8.3 mm provides positive clamping for steady torque transfer and reduced slippage in the toolholder. The three-flute design balances cutting engagement for a very quiet, vibration‑reduced run. For process planning, the manufacturer specifies a reference feed of 0.2 mm/rev in steel up to 800 N; this guidance simplifies setup and helps achieve the intended tool life and hole quality without complex trial runs.

Lower operating cost through extended life

Thanks to the combination of advanced chip-space parameters, a variable relief profile and the protective nano-coating, the tool achieves markedly higher wear resistance and elevated hot hardness. This translates into up to 60% longer tool life in comparable conditions, reducing tooling expenditure and machine downtime. For workshops aiming to rationalise supplies without compromising performance, the tool offers a dependable balance of efficiency and longevity that supports predictable production planning.

FAQ

What materials can this countersink process effectively?
The TECWERK countersink (DIN 335C Ø 31 mm) is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and a range of plastics, thanks to its HSS substrate and nano‑coating.

How much faster can machining be with this tool?
In many applications the optimised geometry and reduced feed force can achieve up to 30% faster countersinking compared with conventional designs.

Is the tool compatible with standard toolholders?
Yes, the shank with three flats from nominal Ø 8.3 mm ensures secure clamping in common collets and holders for stable operation.

What feed should be used as a starting point?
A practical reference is 0.2 mm/rev in steel up to 800 N; this provides a balance between surface quality and tool life for preliminary setup.

Does the nano-coating improve high-temperature performance?
The special nano‑coating increases wear resistance and hot hardness, helping the tool to retain cutting performance at elevated temperatures.
