90° countersink DIN 335 C Ø 10.4 mm, HSS Nano, 3‑flute — TECWERK

A 90° countersink DIN 335 C Ø 10.4 mm designed for efficient deburring and chamfering across steels, stainless and heat‑resistant steels, aluminium, brass and plastics.

• HSS nano coating for high wear resistance
• Three‑cut geometry for extremely smooth run
• Up to 60% longer tool life
• Reduced feed force and faster countersinking

Precision and productivity for industrial countersinking

The 90° countersink DIN 335 C Ø 10.4 mm delivers measurable productivity gains through a combination of geometry and surface engineering. The three‑cut geometry and variable relief reduce torque peaks, which results in a markedly lower feed force and an extremely quiet, vibration‑reduced run. From a production standpoint, this reduces tool load and helps maintain consistent chamfer quality on every workpiece. The robust design supports higher process reliability and contributes to shorter cycle times, achieving up to 30% faster countersinking in many applications.

Durable performance across a wide range of materials

Constructed from HSS and finished with a specialised nano coating, the countersink offers high wear resistance and improved hot hardness. This combination is particularly beneficial when machining a mix of materials: carbon steels, stainless and heat‑resistant steels, aluminium, brass and various plastics are all within the tool’s capability. The engineered coating and optimised cutting geometry extend service life — specified as up to 60% longer tool life — which lowers tooling consumption and supports a more economical production flow without compromising surface finish.

Design features that improve process security

Key design elements include the optimised chip space, variable flank relief and a shank with three flats from nominal diameter 8.3 mm for secure clamping. The tool is right‑hand cutting and the chip‑gullet geometry has been developed to avoid clogging when countersinking softer materials while still evacuating chips efficiently from tougher alloys. These features reduce the likelihood of chatter and edge wear, resulting in repeatable chamfer geometry and consistent edge condition even under demanding conditions.

Practical machining parameters and benefits

For practical planning, the tool tolerates a recommended feed in steel (up to 800 N) of around 0.15 mm/rev, giving a balance between surface quality and throughput. The 90° angle ensures standard chamfer profiles suitable for deburring and lead‑in preparation. By combining the HSS substrate with the nano coating, the tool maintains sharp cutting edges longer and resists thermal softening, which is particularly important when processing heat‑resistant steels. The overall effect is a secure, efficient countersinking operation that supports both one‑off jobs and serial production.

FAQ

What materials can be machined with this countersink?
The TECWERK 90° countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and various plastics, thanks to its HSS construction and nano coating.

What is the recommended feed for countersinking in steel?
For steel up to 800 N, a feed of approximately 0.15 mm per revolution is recommended for optimal balance between finish and productivity when using this countersink.

How does the nano coating benefit process reliability?
The nano coating on the TECWERK countersink increases wear resistance and hot hardness, which helps to maintain cutting edge integrity and extend tool life under elevated temperatures.

Does the shank design improve clamping security?
Yes; the shank features three flats from nominal Ø 8.3 mm, which improves clamping stability and reduces slippage in standard toolholders.

What advantages does the three‑cut geometry provide?
The three‑cut geometry delivers a smoother run, lower feed forces and reduced vibration, resulting in consistent chamfer quality and longer tool service life.
