TECWERK Countersink DIN 335C Ø10.4 mm – HSS‑Co, TiAlN, 90°

The TECWERK countersink DIN 335C Ø10.4 mm is a high‑performance 90° countersink designed for fast, accurate deburring and chamfering across a broad range of metals and plastics

• High‑performance HSS‑Co construction
• TiAlN coating for extended tool life
• Spiral flutes for smooth chip evacuation
• Precise 90° countersink with rattle‑free finish

Consistent, burr‑free countersinking for reliable assemblies

The tool is engineered to deliver a clean, concentric chamfer with minimal vibration thanks to the three unequal convex cutting edges and spiral fluting. This geometry reduces chatter and produces a rattle‑free finish, which translates into fewer rejected parts and more predictable assembly times. For production environments where joint consistency matters, the design ensures the countersink is repeatable and stable under moderate feed forces.

Efficient cutting and markedly longer tool life

Made from HSS‑Co and treated with a TiAlN coating, the countersink benefits from improved heat resistance and wear protection, enabling higher cutting speeds and longer intervals between tool changes. The spiralised cutters reduce cutting forces—documented advantages include approximately 60% lower feed force and 50% lower radial force—so cycle times are optimised and machine loads are minimised. For machine shops seeking better throughput, these efficiencies reduce downtime and extend tool life in daily use.

Versatile performance across common workshop materials

This countersink conforms to DIN 335 C and is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and various plastics. The cylindrical shank fits standard toolholders and the right‑hand cutting direction matches conventional rotation on most lathes and milling heads. Where delicate finishes are required—such as in fittings, housings or visible fastenings—the combination of geometry and coating produces precise chamfers without material tearing or excessive rework.

Practical integration and process advantages

Feeds in steel up to 800 N are specified at 0.115 mm/rev, enabling process planning with predictable material removal rates. The DIN format and cylindrical shank simplify tool library management, while the spiral relief assists chip evacuation in through‑hole and blind‑hole applications. In short runs and batch production alike, the countersink supports steady, measurable improvements in productivity and surface quality.

FAQ

What materials can be processed with this countersink?
The TECWERK countersink is designed for a wide range of materials and is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and many plastics.

Is the tool suitable for high‑speed machining?
With an HSS‑Co substrate and a TiAlN coating, the countersink allows higher cutting speeds than uncoated variants and offers improved heat resistance and wear performance.

How does the spiral geometry benefit production?
Spiralised flutes promote smooth chip evacuation and reduced vibration; this results in a cleaner chamfer and lower forces during cutting, which supports longer tool life and more consistent parts.

What standards and shank type does the tool follow?
The tool conforms to DIN 335 C and is supplied with a cylindrical shank compatible with standard toolholders.

Can the countersink be used for precision visible chamfers?
Yes, the unequal convex cutting edges and TiAlN coating deliver precise, rattle‑free finishes that are suitable for visible fastenings and aesthetic components.
