NC spot drill "NC-Anbohrer D.3mm VHM TiAlN 90Grad TECWERK" — solid carbide, 90° centring tip

NC-Anbohrer D.3mm VHM TiAlN 90Grad TECWERK is a compact centre‑drilling tool for accurate, repeatable starts and simultaneous chamfering on NC machines and boring mills

• Solid carbide, DIN 6535‑HA shank
• TiAlN coating for heat and wear resistance
• 90° tip for centring and chamfering
• Suited for high‑strength steels and stainless steel

Accurate starts and one‑pass chamfering for shorter cycle times

The solid carbide construction together with a 90° tip provides a stable, reproducible pilot hole that significantly reduces runout and subsequent tool wear. Designed for position‑accurate and rapid spot drilling on NC machines and boring mills, the tool allows centring and chamfering of tapped holes in a single operation, which shortens cycle time and reduces handling between machining steps. The combination of geometry and material supports consistent hole quality and reliable thread preparation.

Thermal stability and extended tool life through TiAlN coating

The TiAlN (titanium aluminium nitride) coating increases surface hardness and resistance to thermal softening at elevated cutting temperatures. As a result, the tool sustains cutting performance during higher intensity starts and in demanding materials, delivering longer service life and fewer tool changes. The coating also improves oxidation resistance and helps to maintain a sharp cutting edge under intermittent contact typical for spot drilling operations.

Machine compatibility and guided feed recommendation

Equipped with a cylindrical shank to DIN 6535‑HA, the tool integrates seamlessly into standard toolholders and collets used in automated machining centres. Its right‑hand cutting geometry is optimised for conventional spindle rotation. For machining in steel, a feed guidance of 0.05 mm/rev at forces up to 800 N is specified, offering a reliable baseline for process planning and spindle load calculations. The tool’s attributes support efficient NC programming and predictable production output.

Broad material capability and workshop workflow benefits

The design and material combination make the tool particularly suitable for high‑strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals. The ability to centre and deburr or chamfer in one pass reduces the need for secondary operations, improving throughput and lowering overall part handling. In practice, this leads to fewer set‑ups, reduced fixture time and a more streamlined production flow, while maintaining the dimensional accuracy required for subsequent threading operations.
