Precise centring, high wear resistance and a DIN‑compliant cylindrical shank combine to reduce set‑up time and ensure repeatable results — with a TiAlN‑coated solid carbide tip and 142° point angle for reliable centring and chamfering; order directly via Metav Werkzeuge or consult the specialists for application support.

TECWERK NC spot drill D 5 mm — Solid carbide, TiAlN, 142°

A TECWERK NC spot drill D 5 mm designed for fast, position‑accurate spotting, centring and simultaneous chamfering of threaded holes on CNC machines and drilling centres.

• Solid carbide with TiAlN coating
• 142° precision point for clean centring
• Cylindrical shank to DIN 6535‑HA
• Suited for high‑strength steels and stainless steels

Consistent centring and long tool life for CNC production

The TECWERK NC spot drill D 5 mm combines solid carbide construction with a TiAlN surface finish to deliver high wear resistance in demanding production environments. The 142° point angle produces a concise, stable centre that reduces wandering at plunge start, while the coating increases heat resistance during frequent cycle starts. This results in fewer tool changes and more consistent hole preparation across batches, supporting efficient machining on modern CNC machines.

Accurate clamping and concentricity with DIN cylindrical shank

A cylindrical shank manufactured to DIN 6535‑HA with a h6 diameter tolerance ensures precise seating in standard toolholders and automatic chucks. The tight tolerance reduces run‑out and improves concentricity between the spot drill and subsequent twist drills, lowering the risk of misaligned threads. For workshops that use automated spindles or quick‑change systems, the DIN shank provides a dependable interface for repeatable results.

Designed for tough materials and one‑pass preparation

This spot drill is optimised for a wide material range: high‑strength steels, cast steels, grey cast iron, stainless steels and non‑ferrous metals. The tool features right‑hand cutting and is rated for a practical feed of 0.07 mm/rev in steel up to 800 N, allowing controlled material removal during the spotting operation. By centring and chamfering in one pass, the cutter shortens the process chain, delivering prepared holes ready for threaded operations with improved axial alignment.

Practical compatibility and application benefits

The geometry is matched to centre standard twist drills with point angles from 120–140°, so the spot drill works as a reliable lead‑in for common drill types. Its design supports fast, position‑accurate spotting on NC machines and drilling centres, improving process stability and reducing setup iterations. The combination of carbide body and protective coating keeps the cutter productive under repetitive spotting cycles typical in industrial production.

FAQ

What materials is this spot drill suitable for?
The TECWERK NC spot drill D 5 mm is suited to high‑strength steels, cast steel, grey cast iron, stainless steels and non‑ferrous metals as indicated in the technical data.

Will the shank fit standard CNC toolholders?
Yes. The cylindrical shank is made to DIN 6535‑HA with a h6 tolerance for secure seating in standard chucks and toolholders.

What advantage does the 142° point angle provide?
A 142° point produces a stable, narrow centre that reduces wandering on plunge start and provides a clean chamfer for subsequent threading or drilling operations.

Can this be used to centre twist drills?
Yes. The geometry is compatible with twist drills that have point angles between 120° and 140°, enabling reliable transfer from spotting to drilling.

What cutting data should be used as a guideline?
A practical reference is a feed of 0.07 mm/rev in steel up to 800 N; actual parameters should be adjusted to machine rigidity and material condition.
