TECWERK 90° Countersink D 10.4 mm — HSS, extra‑long, 3 flutes

The TECWERK 90° Countersink D 10.4 mm is an extra‑long, high‑speed steel countersink designed for precise chamfering and deburring of drilled holes in steel, cast iron and non‑ferrous metals.

• HSS material, DIN 335 C standard
• 90° countersink angle for standard fasteners
• Extra‑long shank for increased reach

Precision and performance for chamfering tasks

Built to the DIN 335 C specification and made from HSS, this countersink delivers consistent geometry essential for repeatable chamfers. The tool’s 3 flutes reduce vibration and produce a chatter‑free cut, which improves surface finish and reduces rework. For users unfamiliar with the standard, DIN 335 C defines the geometry and tolerances for tapered countersinks, ensuring compatibility with industry fasteners and fixtures. The cutter’s ability to operate with a recommended feed in steel up to 500 N of 0.12 mm/rev provides a practical baseline for setting drilling or milling parameters in a production environment.

Longer reach and secure clamping for deep or awkward holes

An extra‑long overall length and a cylindrical shank allow the tool to reach deeper bore edges while remaining compatible with common collets and chucks. The extended shank reduces the need for extension accessories and keeps the tool‑holding interface simple and rigid, which supports concentricity and repeatability across multiple holes. For workshops tackling components with recessed seats or stacked assemblies, this design reduces setup complexity and shortens cycle times by avoiding additional extensions or special holders.

Versatile material suitability with practical benefits

The geometry and material choice make the cutter suitable for steel, cast iron and non‑ferrous metals, enabling workshops to use a single tool across varied jobs. The 90° angle is appropriate for most countersinking needs where a standard chamfer for screw heads or deburring is required. Because the tool trims burrs while forming a clean chamfer in one pass, it reduces subsequent finishing operations and improves the ready‑to‑assemble quality of machined parts.

Practical guidance and efficiency gains

Thanks to the robust HSS construction and DIN conformity, the cutter offers predictable wear behaviour and straightforward regrinding when required, extending service life and reducing tool replacement frequency. The combination of extra length, cylindrical shank and 3‑flute profile results in efficient chip evacuation and minimal vibration, which together support higher process reliability and lower scrap rates in repetitive production runs. For users transitioning from general drilling to precision countersinking, the clear specification simplifies machine setup and inspection.

FAQ

What materials can this countersink handle?
The TECWERK 90° countersink is suitable for steel, cast iron and non‑ferrous metals, as specified in the technical description.

How does the 3‑flute design benefit production?
The three flutes provide improved chip formation and evacuation, leading to a chatter‑free cut and a better surface finish on the chamfered edge.

Is the tool compatible with standard chucks and collets?
Yes, the cylindrical shank is compatible with common collets and chucks used in workshop and production settings.

What does DIN 335 C mean for tool selection?
DIN 335 C defines the countersink geometry and tolerances; choosing a tool to this standard ensures compatibility with widely used fasteners and predictable chamfer dimensions.

Can the tool be reground when worn?
Constructed from HSS and conforming to DIN geometry, the cutter can be reground to extend service life while maintaining the specified chamfer form.
