TECWERK Countersink DIN 335C 90° Ø12.4 mm HSS‑Co TiAlN, Z.3

A TECWERK countersink DIN 335C designed for accurate 90° chamfering and deburring across a wide range of metals and plastics.

• TiAlN coating for extended tool life
• Spiralised three convex flutes for chatter‑free cuts
• 90° angle for standard chamfering and countersinking
• Reduced feed and radial forces for smoother machining

Precision chamfering with stable cutting performance

The HSS‑Co substrate combined with a TiAlN surface layer delivers wear resistance and heat stability that extend tool life in continuous production. Spiralised flutes and three convex cutting edges ensure a smooth chip flow and a round, accurate countersink profile; this reduces vibration and prevents the scalloping typical of straight‑flute designs. For shops aiming to increase first‑pass quality, the result is fewer rework steps and a consistent chamfer every cycle.

Lower forces, improved process reliability

Spiral geometry and unequal flute spacing cut down on cutting shocks: documented advantages include approximately 60% lower feed force and around 50% lower radial force, which together reduce spindle load and improve tool engagement. This makes the countersink suitable for sensitive setups and smaller machines where force peaks otherwise cause poor surface finish or tool deflection. The right‑hand cutting orientation and cylinder shank provide straightforward integration into standard toolholders.

Broad material compatibility for flexible production

Engineered to serve mixed‑material workflows, the tool is effective on steel, stainless and heat‑resistant steels, aluminium, brass and a variety of plastics. The combination of cobalt‑alloy high‑speed steel and TiAlN coating keeps the cutting edge sharp under elevated temperatures, while the spiralised edges maintain chip control when switching between soft and hard substrates. This versatility reduces the need for multiple dedicated countersinks and simplifies tooling decisions.

Designed for long tool life and predictable feeds

Spiralised cutting edges and the high‑performance coating translate into extremely long stand‑times, lowering tooling consumption and downtime. The geometry allows a recommended feed in steel up to 800 N at 0.120 mm/rev, offering a clear starting point for process setup and optimisation. Where surface quality and repeatability matter, the tool helps maintain consistent results across production runs.

FAQ

What materials can be machined with this countersink?
The TECWERK countersink is suitable for steel, stainless and heat‑resistant steels, aluminium, brass and a range of plastics, thanks to its HSS‑Co body and TiAlN coating.

What does the TiAlN coating provide?
TiAlN on the TECWERK 90° countersink increases heat resistance and reduces wear, extending cutting life under thermal stress and supporting higher machining rates.

How does the spiralised flute geometry affect performance?
Spiralised flutes on the TECWERK tool improve chip evacuation and reduce vibration, resulting in rounder, chatter‑free countersinks and more stable machining.

Is the tool compatible with standard toolholders?
Yes, the cylinder shank design and right‑hand cutting configuration allow straightforward mounting in common holders used for countersinking operations.

What is the recommended starting feed for steel?
A useful reference for setup is a feed of 0.120 mm/rev in steel at forces up to 800 N, as indicated for this countersink (SKU 2000865293NW).
