TECWERK Countersink DIN 335 C, 90° – HSS TiAlN, Ø 8.3 mm

A TECWERK countersink DIN 335 C designed for precise countersinking and deburring of drilled holes in steel, cast iron and non‑ferrous metals.

• DIN 335 C, 90° countersink geometry
• Triple cutting edges for chatter‑free cutting
• TiAlN-coated HSS for heat resistance
• Cylindrical shank for secure toolholding

Precision finish for every workshop

The DIN 335 C geometry with a 90° angle provides a consistent seat for fasteners and a clean, repeatable finish. Built in HSS and sharpened to produce a true conical face, this countersink reduces the need for follow‑up machining and ensures uniform alignment of screw heads. For small batch production or maintenance work, the result is reduced rework and more predictable assembly quality, making it suitable for mechanical workshops and industrial toolrooms.

Consistent, chatter‑free cutting

Three precisely ground cutting edges ensure a chatter‑free operation and a smooth surface finish on the countersunk face. The multiple cutters share the load, which lowers vibration and provides dimensional stability when working at moderate feed rates. The TiAlN coating increases thermal resistance and wear life, so the tool maintains cutting geometry longer under intermittent heat build‑up, translating into fewer tool changes and steadier process control.

Broad material compatibility and controlled feed

Manufactured for general workshop use, this countersink is appropriate for steel, cast iron and non‑ferrous metals, enabling one tool to cover a range of applications. Recommended cutting data includes a feed in steel up to 500 N with approximately 0.09 mm/rev, which balances cutting action and surface quality. The compatibility across common substrates reduces tool inventory and simplifies job planning for mixed‑material tasks.

Secure clamping and easy integration into workflows

The cylindrical shank fits standard toolholders and chucks, providing dependable clamping for hand machines and light machine tools. The tool’s design focuses on straightforward handling: fast mounting, reliable concentricity and practical regrinding options. With its extended tool life thanks to TiAlN and solid HSS core, the countersink supports continuous workshop operations and lowers total tooling effort per part.

FAQ

What materials can be processed with this countersink?
The TECWERK countersink is suitable for steel, cast iron and non‑ferrous metals, offering broad material compatibility for workshop and light industrial use.

What is the recommended feed for countersinking in steel?
For steel, follow the guidance of up to 500 N with a feed around 0.09 mm/rev to achieve a balance between surface finish and tool life when using the TECWERK countersink.

Does the TiAlN coating improve tool life?
Yes, the TiAlN coating increases heat and wear resistance, which helps the countersink maintain cutting geometry and extend service life under intermittent thermal load.

How does the three‑edge design affect performance?
The three cutting edges distribute cutting forces, reducing vibration and producing a chatter‑free finish; this leads to smoother countersinks and fewer rejects in production.

Is the shank compatible with standard toolholders?
The cylindrical shank is designed for secure clamping in common chucks and toolholders, making the countersink easy to integrate into existing workshop equipment.
