TECWERK NC centre drill D 4 mm VHM TiAlN 90° — solid carbide, DIN 6535-HA shank

TECWERK NC centre drill D 4 mm VHM TiAlN 90° is designed for position-accurate spot drilling, centring and chamfering of tapped holes in a single operation on NC machines and boring mills

• Solid carbide with TiAlN coating
• Cylindrical shank to DIN 6535-HA
• 90° tip for centring and chamfering
• Suitable for high-strength and stainless steels

Precision where it reduces cycle times

The solid carbide construction and 90° tip geometry enable reliable centring and a defined chamfer in one pass, reducing the need for secondary tools and setups. For production environments this translates into shorter cycle times and fewer handling steps. The centre drill’s combination of rigidity and cutting geometry ensures consistent hole position and repeatable chamfer quality, improving downstream thread engagement and reducing rework.

Hard-wearing coating for extended tool life

Equipped with a TiAlN coating, this tool shows improved resistance to heat and abrasive wear compared with uncoated variants. The coating supports higher cutting temperatures and helps maintain cutting edge integrity when machining demanding alloys. As a result, the tool provides longer service intervals and steadier performance when processing high-strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals.

Secure clamping and machine compatibility

The cylindrical shank to DIN 6535-HA ensures dependable clamping in standard tool holders on NC machines and boring mills, minimising run-out and vibration. Right-hand cutting geometry and precise shank tolerances contribute to a stable machining process, which is particularly important when accuracy is required for subsequent threading or fit operations. The standardised shank also simplifies tool changeover across similar machine tools.

Practical feed guidance and workshop benefits

With a recommended feed in steel up to 800 N of 0.06 mm per revolution, the tool offers a clear starting point for process set-up and optimisation. Using a single tool for centring and chamfering reduces tool inventory and shortens fixture time, bringing measurable efficiency gains to both one-off jobs and series production. The robust design supports high machine utilisation while maintaining consistent hole quality, making it a reliable component of a modern workshop’s tooling strategy.
