TECWERK 90° Countersink DIN 335 C – 15 mm, HSS nano-coated, 3-flute

TECWERK 90° Countersink for precision chamfering and deburring across steels, non-ferrous metals and plastics in workshop and production environments.

• HSS with Nano coating for high wear resistance
• 90° DIN 335 C geometry for precise chamfering
• 3-flute design for smooth running and fast chip removal
• Reduced feed force; optimised for steel and aluminium

Faster, more reliable countersinking for continuous production

The countersink delivers consistently lower cutting resistance thanks to a variable relief and specially shaped chip space that reduce thermal load and minimise chatter. With a nano coating and an HSS substrate, the tool achieves high wear resistance and improved hot hardness, which translates into longer stand times and fewer tool changes. The combination of these features means more reliable cycle times and reduced rework, turning a common secondary operation into a predictable, efficient process step.

Geometry engineered to cut time and simplify clamping

The 90° DIN 335 C profile and a 3-flute configuration provide a balanced cutting action and an even surface finish, while the shank is supplied with three flats from nominal Ø 8.3 mm for secure clamping in collets or chucks. Right-hand cutting and a variable back-off help to reduce the required feed force, so material engagement is smoother and tool deflection is minimised. For CNC planning, the recommended reference feed in steel under loads up to 800 N is 0.15 mm/rev, enabling reliable process settings without excessive trial cycles.

Broad material capability and process benefits

The tool is suitable for a wide range of workpiece materials — steel, stainless and heat-resistant steels, aluminium, brass and plastics — making it a versatile choice for mixed-production environments. The engineering behind the chip space and coating not only reduces cutting forces but also improves chip evacuation, which supports consistent geometry of the chamfer and decreases the risk of surface damage. Fewer interruptions for tool changes and a calmer running tool also contribute to a safer, more economical workflow on the shopfloor.

FAQ

What materials can this countersink process effectively?
The TECWERK 90° countersink is designed for steel, stainless and heat-resistant steels, aluminium, brass and various plastics, providing a versatile solution for mixed workshops.

How does the nano coating improve performance?
The nano coating on this countersink enhances wear resistance and hot hardness, which increases tool life and maintains cutting performance under elevated temperatures.

Is the shank suitable for standard collets and chucks?
Yes — the shank is supplied with three flats from nominal Ø 8.3 mm to ensure secure clamping in conventional collets and chucks, improving concentricity and reducing slippage.

Can the tool be used on CNC machines and what is a reference feed?
The countersink is suitable for CNC applications; a practical reference feed in steel under loads up to 800 N is 0.15 mm/rev, which assists in process programming and consistent results.

What operational benefits can be expected compared with standard countersinks?
Expect lower cutting forces, quieter running, faster material removal rates and extended stand time due to the combination of HSS, nano coating and optimised geometry.
