31mm Countersink 90° HSS TiN 3-Flute Cylinder Shank, Burr-Free Steel/Grey Metalls Deburring - TECWERK

Take advantage of the combination of durable HSS construction, a TiN coating for extended tool life and a three‑flute geometry that delivers a chatter‑free cut; order the tool directly via Metav Werkzeuge or ask their consultants for application advice.

TECWERK Countersink DIN 335 C, 90° Ø31 mm (HSS TiN, 3‑flute)

The TECWERK Countersink DIN 335 C Ø31 mm is a high‑precision countersink designed for reliable countersinking and deburring of drilled holes in steel, cast components and non‑ferrous metals, optimised for rattle‑free performance.

• HSS construction with TiN coating
• DIN 335 C, 90° countersink geometry
• Three‑flute design for chatter‑free cutting
• Suitable for steel, castings and non‑ferrous metals

Durable construction for demanding metalworking

Manufactured from high‑speed steel (HSS) and finished with a TiN coating, this countersink offers a robust combination of toughness and wear resistance. The coating reduces friction and increases service life under continuous use, which translates into fewer tool changes and lower downtime. The DIN 335 C geometry ensures consistent contact with the workpiece, while the three‑flute design provides stable cutting forces; this results in cleaner chamfers and reduced rework compared with conventional two‑flute shapes.

Stable cutting behaviour and improved surface finish

The three cutting edges deliver a rattle‑free cutting action that improves concentricity and surface appearance of the countersunk hole. For operations in steel the tool’s recommended feed behaviour is specified as 0.22 mm/rev at up to 500 N, which balances chip evacuation with surface integrity. The cylindrical shank fits standard chucks and collets, enabling straightforward integration into existing drilling or machining cycles while maintaining consistent alignment for precision results.

Practical benefits for production efficiency

Using a single countersink that reliably handles a range of materials reduces tool inventory and simplifies workflow. The combination of HSS base material and TiN coating provides cost‑effective durability, while the three‑flute geometry reduces vibration and improves repeatability. These attributes contribute to shorter cycle times and a lower rate of defective parts, supporting steady throughput in workshops and production lines without the need for frequent dressing or replacement.

Typical applications and workshop usage

This tool is intended for applications in mechanical engineering, metal fabrication and maintenance where clean, accurate chamfers and burr‑free holes are required. It is suitable for workshop drills and small machining centres that accept cylindrical‑shank tooling and adheres to the familiar DIN 335 C standard for countersinks. The design suits both single‑part finishing and small batch production, especially where a consistent surface finish and reliable tool life are priorities.
