Countersink DIN 335 C Ø20.5 mm HSS TiN, 3‑flute — TECWERK

The Countersink DIN 335 C Ø20.5 mm HSS TiN, 3‑flute is engineered for reliable countersinking and deburring of drilled holes in steel, cast components and non‑ferrous metals.

• HSS core with TiN coating
• 90° angle for standard chamfers
• Three‑flute geometry for chatter‑free cutting
• Cylindrical shank for secure mounting

Consistent hole quality through hardened geometry and coating

The combination of HSS material and a TiN coating provides a stable cutting edge that maintains sharpness under repetitive use, which results in uniform chamfers and reduced rework. Conforming to DIN 335 C, the tool’s 90° flank produces the standard countersink profile expected in assembly and fastening operations. The three cutting edges yield a chatter‑free cutting action, so each hole receives a clean finish with minimal burr formation and fewer secondary operations.

Faster, more efficient processing with predictable feed parameters

Designed for production environments, the tool enables controlled material removal: a recommended feed of 0.2 mm/rev in steel at cutting forces up to 500 N supports stable machining and predictable cycle times. The three‑flute design increases cutting engagement and stability, allowing slightly higher feeds than single‑flute counterparts while maintaining surface integrity. This focused performance reduces machining time per hole and contributes to improved overall throughput.

Robust compatibility and longer tool life for reliable routines

A cylindrical shank ensures straightforward mounting in standard tool holders and provides secure retention during countersinking. The TiN coating lowers friction and enhances wear resistance, extending usable life and reducing downtime for tool changes. Suitable for use on steel, cast iron and non‑ferrous metals, the countersink is a practical choice for workshops seeking consistent, durable tooling without complex setup changes.

FAQ

Which materials can be machined with this countersink?
The TECWERK countersink is suitable for steel, cast iron and various non‑ferrous metals, making it versatile for general workshop and production tasks.

What feed should be used when countersinking steel?
For the Countersink DIN 335 C Ø20.5 mm HSS TiN, 3‑flute, a feed of 0.2 mm/rev is recommended in steel at cutting forces up to 500 N to maintain stability and surface quality.

How does the TiN coating benefit tool performance?
The TiN coating reduces friction and improves wear resistance, which helps preserve the cutting edge, lowers heat build‑up and extends the service life of the countersink.

Is this countersink suitable for series production?
Yes. Compliance with DIN 335 C, the three‑flute design for stable cutting and the cylindrical shank for secure mounting make the tool well suited to repetitive production work.

What distinguishes the three‑flute version from two‑flute countersinks?
The three‑flute geometry delivers smoother chip evacuation and a chatter‑free cut, improving finish quality and allowing more consistent feeds compared with fewer‑flute variants.
