TECWERK NC centre drill D3 mm — Solid carbide, TiAlN, 142°

TECWERK NC centre drill D3 mm TiAlN is a solid‑carbide spot drill designed for position‑accurate spot drilling and simultaneous chamfering on CNC machines and drilling centres

Solid carbide VHM with TiAlN coating
142° centre angle for precise chamfering
Cylindrical shank to DIN 6535‑HA
Suitable for high‑strength steels and stainless

Faster, accurate pre‑drilling and chamfering for shorter cycle times

The combination of solid‑carbide (VHM) body and TiAlN coating delivers high rigidity and improved wear resistance, enabling consistent, position‑accurate centring even under intermittent loads. The 142° tip angle provides a controlled chamfer in the same pass as the centre operation, reducing the need for additional tools and lowering cycle time. For practical machining parameters the tool recommends a feed in steel up to 800 N: 0.05 mm/rev, which helps maintain concentricity and surface finish without overloading the cutter.

Reliable integration with CNC toolholders and drilling rigs

A cylindrical shank manufactured to DIN 6535‑HA ensures secure clamping and repeatable positioning in standard toolholders, while the h6 diameter tolerance supports tight concentricity in automated setups. The right‑hand cutting geometry and defined spiral length contribute to chip evacuation and stable cutting conditions on high‑performance machines. These characteristics make the centre drill particularly suitable for automated workflows where repeatability and minimal set‑up time are essential.

Wide material compatibility and fewer tool changes

This centre drill is optimised for a broad range of materials: high‑strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals. The TiAlN coating raises the thermal resistance of the cutting edge, extending tool life when machining tougher alloys and stainless grades. By combining centring and chamfering in a single operation, the tool reduces tool inventory and changeovers, enhancing workshop efficiency and contributing to predictable production throughput.
