TECWERK NC centre drill D16 mm — solid carbide, TiAlN, 90°

The TECWERK NC centre drill D16 mm is a solid-carbide centre drill designed for position-accurate and rapid centre drilling and chamfering on NC machines and boring mills.

*Solid carbide with TiAlN coating for wear resistance *90° tip for precise centring and chamfering *Cylindrical shank to DIN 6535-HA for secure mounting *Suitable for high-strength steel, stainless and non-ferrous

High-performance construction for consistent centring

The tool is manufactured from solid carbide, giving high rigidity and thermal stability during interrupted cuts. The TiAlN coating increases surface hardness and heat resistance, extending tool life under elevated temperatures. With a 90° tip geometry the drill performs accurate centring while creating a chamfer in the same operation, reducing cycle times and tool changes. This combination of materials and geometry ensures repeatable results in precision production.

Designed for demanding materials and reliable feeds

Rated for machining high-strength steels, cast steel, grey cast iron, stainless steels and non‑ferrous metals, the centre drill is balanced for tough job-shop conditions. A recommended feed in steel up to 800 N is 0.14 mm/rev, which achieves efficient material removal without sacrificing surface quality. The specification clarifies how to set feed per revolution in CNC programmes and supports predictable process planning in serial production.

Secure mounting and machining orientation

The cylindrical shank to DIN 6535-HA provides standardised fitting and concentricity in qualified toolholders, minimising runout and improving hole accuracy. The tool is right‑hand cutting, optimised for standard spindle rotation, and therefore integrates smoothly into existing NC setups. Reduced vibration and stable cutting conditions translate into improved cycle reliability and less rework in precision assemblies.

Practical advantages for workflow and productivity

By combining centring and chamfering in one pass the tool reduces handling and setup time on milling and boring centres, supporting faster throughput on repeat jobs. The robust coating and carbide body lower the frequency of tool changes, which benefits maintenance planning and cost-per-part calculations. Documentation of the core specifications enables straightforward inclusion in machining process sheets and quality traces.

FAQ

What materials can this centre drill machine? The TECWERK NC centre drill is suitable for high-strength steels, cast steel, grey cast iron, stainless steels and non‑ferrous metals, as stated in the technical description.

How should the tool be mounted for best accuracy? Mount the tool by its DIN 6535-HA cylindrical shank in a suitably rated toolholder; this ensures concentricity and minimises runout for accurate centring.

Is chamfering possible in the same operation as centring? Yes, the geometry of the tool permits centring and chamfering of threaded holes in a single pass, reducing setup time and tool changes.

What feed rate is recommended for steel? A practical feed recommendation for steel up to 800 N is 0.14 mm/rev, which balances material removal with surface quality.
