Take advantage of the combination of solid carbide construction, TiAlN coating and a 142° point for fast, accurate spot-drilling on NC machines — order directly via Metav Werkzeuge or ask the consultants for application guidance.

TECWERK NC centre drill D 3 mm — solid carbide, TiAlN, 142° point

The TECWERK NC centre drill D 3 mm is a solid carbide centre/spotting tool designed for positions-accurate pre‑drilling and chamfering on NC machines and drill rigs.

• Solid carbide construction for rigidity and accuracy
• TiAlN coating for higher heat resistance
• 142° point angle for precise centring
• Cylindrical shank to DIN 6535‑HA for secure clamping

High-speed precision for NC workflows

Engineered for repeatable, accurate spot‑drilling, this solid spotting tool combines a solid carbide body with a TiAlN-coated cutting geometry to maintain edge life under elevated temperatures. The 142° point angle delivers fast, self‑centring starts and reduces vibration during entry, which supports consistent hole location on automated centres. For NC production environments this results in fewer rejects and shorter cycle times, with a recommended feed in steel up to 800 N of 0.05 mm/rev to balance tool life and productivity.

Long life and broad material compatibility

The TiAlN coating increases thermal resistance and hardness at the cutting edge, extending service life when machining demanding materials. The tool is especially suitable for high-strength steels, steel castings, grey cast iron, stainless steels and a range of non‑ferrous metals. Where a combination of centring and chamfering in a single pass is desired, the tool reduces handling steps and improves process reliability. The design also permits centring of solid carbide drills with point angles between 120° and 140°, ensuring compatibility with common drilling tools.

Secure mounting and practical workshop integration

Featuring a cylindrical shank to DIN 6535‑HA, the tool fits standard chucks and toolholders for safe, repeatable clamping. The right‑hand cutting geometry and the spotting profile enable precise initiation of tapped holes and accurate chamfering in one operation, which streamlines set‑up on both NC machines and drill rigs. Clear technical specifications and predictable feeds support process planning; for complex applications Metav's technical advisers can provide tailored recommendations.
