TECWERK Countersink DIN 335 C, 90° Ø 10.4 mm — HSS‑Co, TiAlN, 3‑flute

The TECWERK countersink is a 90° DIN 335 C chamfering tool designed for high‑performance finishing across a wide range of metals and plastics

• TiAlN coating for extended tool life
• HSS‑Co substrate for improved toughness
• Spiralised, 3 unequal convex flutes for smooth cuts
• 90° geometry for standard chamfers and V‑preps

Consistent production throughput through robust material and coating

The combination of a HSS‑Co substrate and TiAlN coating delivers a durable cutting system that tolerates elevated temperatures and abrasive wear. In repetitive countersinking operations this design reduces downtime by extending service intervals; the coated cobalt high‑speed steel base keeps the cutting edge stable under load. For production environments seeking measurable gains in efficiency, the tool’s construction translates into lower wear rates and fewer regrinds, supporting uninterrupted manufacturing.

Geometry engineered for fast, burr‑free chamfers

Spiralised cutting edges with three unequal convex flutes and a 90° point produce a clean, concentric chamfer with minimal chatter. The spiral fluting evacuates chips effectively, while the convex rake reduces the tendency to grab, resulting in a round, rattle‑free countersink even when machining mixed materials. Operators will notice a significant reduction in burr formation and improved surface quality, which simplifies downstream deburring and assembly.

Lower cutting forces for safer, more predictable machining

The tool’s flute geometry and cutting angles yield approximately 60% lower feed force and 50% lower radial force, reducing load on spindles and fixturing. These force reductions allow for steadier feeds and improved hole concentricity, particularly when working with thin‑walled components or softer alloys. The right‑hand cutting orientation and cylinder shank ensure secure clamping and predictable chip flow, making the tool suitable for bench and CNC countersinking alike.

Versatile application range and entry‑level cutting data

Designed to conform to DIN 335 C, the countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and various plastics. The spiralised HSS‑Co cutting edges combined with the TiAlN finish provide very high stand times across these materials. For initial set‑up, a recommended feed in steel at cutting forces up to 800 N is approx. 0.115 mm per rev, though final parameters should be adjusted to machine rigidity and material condition. This balance of versatility and endurance makes the tool a reliable choice for maintenance shops and production lines alike.

FAQ

What materials can this countersink handle?
The TECWERK countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and various plastics, owing to its HSS‑Co substrate and TiAlN coating.

How does the TiAlN coating benefit performance?
The TiAlN coating increases surface hardness and heat resistance, enabling the tool to maintain edge stability and achieve longer stand times during repetitive countersinking tasks.

Is the tool compatible with CNC spindles?
Yes. The cylinder shank and right‑hand cutting direction make the countersink compatible with handheld and CNC spindles, provided secure clamping is used.

What makes the three unequal flutes advantageous?
The unequal convex flute geometry reduces harmonic vibration and improves chip evacuation, resulting in cleaner chamfers and less chatter compared with symmetric designs.

Which standard does the countersink conform to?
The countersink is manufactured to DIN 335 C, ensuring a standard 90° chamfer geometry suitable for many general engineering applications.
