TECWERK Countersink set DIN 335 C, 90° — HSS‑Co with TiAlN coating

The TECWERK Countersink set DIN 335 C 90° is a precision countersinking solution designed for clean, repeatable chamfers and fastener seating across ferrous and non‑ferrous materials.

• HSS‑Co body with high wear resistance
• TiAlN coating for extended tool life
• Spiral flutes with three convex cutting edges
• 90° countersink angle for standard fasteners

Longer production runs with fewer interruptions

The set’s HSS‑Co construction, combined with a TiAlN surface layer, is engineered to withstand demanding cutting conditions and to reduce wear. The spiralised cutter geometry channels chips away from the hole, lowering friction and heat build‑up; the result is extremely high tool life and fewer tool changes. Measurable performance improvements are supported by the tool’s design: 60% lower feed force and 50% lower radial force reduce machine load and help maintain cycle times in series production. For workshops seeking steady throughput and predictable maintenance intervals, this tool architecture translates directly into improved operational efficiency and less unplanned downtime.

Precise, chatter‑free countersinking for reliable assembly

The spiral flutes with three convex cutting edges produce a round, exact and chatter‑free countersink finish, while the standard 90° angle ensures correct seating for common fasteners. The cutters are right‑hand cutting and spiral‑fluted to initiate smooth engagement and to avoid abrupt cutting forces that cause irregular edges. For less experienced operators, these geometric choices mean easier set‑up and consistently good surface quality; for precision shops, the same features reduce rework and improve joint reliability. The term “convex cutting edges” refers to the outwardly curved teeth that maintain constant contact during entry, smoothing initial penetration and preventing pull‑through.

Wide material range for versatile workshop use

The geometry and materials make the set suitable for a broad spectrum of materials: steel, stainless steel, heat‑resistant steels, aluminium, brass and various plastics. The cobalt alloy of the HSS‑Co grade gives the cutters greater hardness retention at elevated temperatures than standard HSS, while the TiAlN coating further increases heat resistance and reduces built‑up edge on non‑ferrous substrates. This combination enables high cutting speeds and efficient chip evacuation even when moving between different workpieces, making the set a practical choice for mixed‑material production runs and maintenance work in metalworking shops.

Neat storage and straightforward workshop logistics

The countersinks are supplied in a robust plastic case that keeps the cutters organised and protected in the tool cabinet or machine trolley. The compact packaging aids rapid tool identification and fast changeovers, contributing to smoother workflows on the shop floor. Technical information and additional application advice are available from Metav Werkzeuge for those who require cutting data or recommendations for feed and speed. The set’s balance of performance, durability and practical storage supports both production lines and small workshops seeking reliable, repeatable results.

FAQ

What materials are suitable for these countersinks?
The TECWERK countersink set is suitable for steel, stainless steel, heat‑resistant steels, aluminium, brass and various plastics, thanks to the HSS‑Co substrate and TiAlN coating.

How does the TiAlN coating improve performance?
The TiAlN coating on the countersinks increases heat resistance and reduces friction, which extends tool life and helps maintain sharpness during longer runs.

Why are spiral flutes beneficial for countersinking?
Spiral flutes improve chip evacuation and produce smoother cutting forces; in this set, the spiralised geometry contributes directly to chatter‑free finishes and reduced cutting loads.

What diameter range is covered by the set?
The set covers a diameter range of 6.3–20.5 mm, offering flexibility for a range of fastener sizes and hole preparations.

Is the set supplied in protective packaging?
Yes, the countersinks are supplied in a plastic case for organised storage and safe transport.
