12.4mm Countersink 90° Three-Point HSS-Co TiAlN, Spiral Fluted Z3, For Steel Aluminium Brass Plastics - TECWERK

Take advantage of HSS‑Co cutting geometry and TiAlN surface protection for long tool life and precise, chatter‑free countersinking. The reduced feed and radial forces ensure smoother drilling operations and less rework, making the tool ideal for mixed‑material production; order the countersink directly via Metav Werkzeuge or request specialist advice from their consultants.

TECWERK conical countersink DIN 335 C, 90° — HSS‑Co TiAlN, Ø 12.4 mm

The TECWERK conical countersink is a spiral‑fluted, three‑cut tool designed for burr‑free countersinking and deburring in steel, stainless and heat‑resistant steels, aluminium, brass and plastics.

• HSS‑Co with TiAlN coating
• Spiral‑fluted, 3 unequal convex edges
• 90° countersink angle for chamfering
• Lower feed and radial forces for smooth cuts

Precision and performance for demanding production

The spiralised design with three unequal convex cutting edges provides a rounded, precise, and rattle‑free countersink that reduces the risk of workpiece damage. Manufactured from cobalt‑alloyed HSS (HSS‑Co) and finished with a TiAlN coating, the geometry and surface treatment combine to resist thermal wear and extend cutting life. The conformity to DIN 335 C ensures a standardised form (Form C), which simplifies integration into established machining processes and assures repeatable results across batches.

Lower forces, fewer rejects and predictable feeds

Thanks to the spiral flutes and optimised cutting angles, the tool achieves approximately 60% lower feed force and 50% lower radial force compared with conventional straight‑flute countersinks. This reduction in mechanical load leads to fewer vibrations, improved surface finish and reduced burr formation. For hard machining conditions, a recommended feed in steel (up to 800 N) is 0.120 mm/rev, which balances efficient material removal with tool life. The right‑hand cutting action and cylindrical shank enable steady engagement in common chucks and holders for stable operation.

Versatility across materials and practical application guidance

The spiral‑fluted countersink is suitable for a broad material range: steel, stainless and heat‑resistant steels, aluminium, brass and plastics. The TiAlN layer increases heat resistance and reduces adhesion when working non‑ferrous alloys, while the HSS‑Co substrate maintains edge stability under intermittent cutting. For users uncertain about feed or clamping setups, Metav Werkzeuge can supply application advice and confirm compatibility with existing spindles or collet systems.

FAQ

Which materials can this countersink machine?
The TECWERK conical countersink is suited to steel, stainless and heat‑resistant steels, aluminium, brass and various plastics, as stated in the product specification.

What does the TiAlN coating deliver in practice?
The TiAlN surface increases oxidation and heat resistance, reduces edge wear at elevated temperatures and helps prevent built‑up edge when machining non‑ferrous alloys.

What feed is recommended for steel applications?
For steel conditions up to 800 N, a feed of 0.120 mm per revolution is quoted for stable cutting and good tool life.

Is the tool compatible with standard machine spindles?
The tool has a cylindrical shank and right‑hand cutting; it is compatible with standard chucks and holders that accept the shank diameter—refer to Metav Werkzeuge for specific collet or chuck compatibility.

Which standard and form does the countersink follow?
The countersink conforms to DIN 335 C (Form C) for conical countersinks, ensuring standardised geometry for industrial use.
