TECWERK Countersink DIN 335C 90° D 16.5 mm — HSS Nano, 3‑flute with 3‑flats shank

A TECWERK Countersink DIN 335C 90° D 16.5 mm designed for precision chamfering and countersinking in steel, stainless and heat‑resistant steels, aluminium, brass and plastics

• HSS with nano coating for wear resistance
• 90° angle for standard countersinking tasks
• 3‑flute geometry for quiet, stable running
• Shank with 3 flats for reliable clamping

Enhanced efficiency through optimised geometry and coating

The combination of HSS substrate and a nano coating delivers a measurable improvement in cutting performance. The coating reduces friction and heat build‑up, which translates into up to 60% longer tool life and lower tool consumption in production. The 90° angle and precisely ground cutting edges ensure consistent chamfers and countersinks, while the 3‑flute design promotes stable rotation and reduced vibration. These technical choices result in a countersinking process that requires significantly less feed force, improving cycle times and reducing machine load.

Faster, cleaner results thanks to chip control and variable relief

A variable relief geometry and carefully developed chip space parameters are responsible for the tool’s quieter run and improved material removal. The optimised chip space prevents re‑cutting and enables chips to evacuate cleanly from the countersink, which helps achieve a superior surface finish with fewer burrs. In steel applications the recommended feed performance is 0.2 mm/rev at cutting forces up to 800 N, offering a practical balance between speed and finish. The result is more predictable machining and a reduced need for rework.

Broad material compatibility for flexible workshop use

This countersink is specified for use in a wide range of materials: steel, stainless and heat‑resistant steels, aluminium, brass and various plastics. The right‑hand cutting direction and robust HSS construction maintain cutting stability across different substrates, while the coating preserves hardness at elevated temperatures. For mixed‑material production runs or repair work, the tool provides dependable chamfering without frequent tool changes, increasing throughput and simplifying tool inventory.

Secure clamping and reliable handling for production environments

The shank is supplied with three flats from nominal Ø 8.3 mm, ensuring positive clamping in common collets and chucks. This mechanical design reduces the risk of slippage during high torque operations and supports repeatable axial positioning for series work. Combined with the countersink’s balanced flute geometry, the tool offers extremely smooth running and a consistent hole profile — advantages that directly contribute to reduced scrap rates and more efficient downstream assembly.

FAQ

What materials can be processed with this countersink?
The TECWERK countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and various plastics, offering versatile use in mixed production environments.

What performance improvements can be expected from the nano coating?
The nano coating reduces friction and heat, which results in higher wear resistance, improved hot hardness and the possibility of up to 60% longer tool life compared with uncoated equivalents.

What is the recommended feed for countersinking in steel?
For steel applications under a cutting force up to 800 N the guidance is 0.2 mm per revolution, balancing material removal rate and surface finish.

How does the shank design affect clamping reliability?
The shank with three flats from Ø 8.3 mm ensures positive clamping in collets and chucks, reducing slippage and supporting repeatable axial positioning during series machining.

Why is the 3‑flute geometry beneficial for countersinking?
A 3‑flute geometry provides a stable running tool with improved chip evacuation and reduced vibration, resulting in quieter operation and a more consistent countersink profile.
