Take advantage of the combination of solid carbide construction, TiAlN surface treatment and a 142° tip for fast, position-accurate spotting and simultaneous chamfering on NC machines; order directly via Metav Werkzeuge or consult its specialists for technical matching.

NC spot drill 16 mm – VHM, TiAlN, 142° (TECWERK)

The NC spot drill 16 mm is designed for precise centre‑spotting and chamfering on NC machines and drilling rigs, enabling accurate tap preparation in a single pass.

• Solid carbide construction for high rigidity
• TiAlN coating for heat resistance
• 142° tip for reliable centring and chamfering
• Cylindrical shank to DIN 6535‑HB, tolerance h6

High‑precision positioning and process speed

The tool excels where repeatable, position‑accurate spotting is required. Machined from solid carbide, the cutter provides high rigidity and excellent runout behaviour, which reduces tool wander during entry and keeps hole location within tight tolerances. The 142° tip combines a broad contact area for stable chamfering with a defined centre point for quick drill alignment, so holes are prepared consistently and subsequent drilling or tapping operations start cleanly. This rational design shortens cycle times on CNC machines and drilling rigs while maintaining positional accuracy.

Broad material compatibility and application gains

Developed for general workshop and industrial use, the spot cutter is suitable for a wide range of materials: high‑strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals. Its performance in mixed production runs makes it a versatile choice for toolrooms and production cells. The geometry allows simultaneous centring and chamfering of threaded holes, eliminating a separate chamfering pass and reducing handling. Where precise tap entry is required, the single‑operation approach reduces set‑up steps and minimises cumulative tolerances.

Durable coating and operational reliability

The TiAlN coating offers thermal and wear resistance, improving performance under interrupted cuts and higher temperatures typical of spotting and chamfering operations. Coating plus carbide substrate gives extended edge life under moderate feeds, while the right‑hand cutting geometry ensures standard spindle rotation compatibility. The combination of material and coating supports consistent surface finish at the entry point and maintains tool form over longer production runs, which in turn reduces frequency of tool changes and increases overall equipment effectiveness.

Practical data for process planning

Key dimensions and tolerances enable easy integration into existing tool holdings: Ø 16 mm, overall length 80 mm, spiral length 26 mm, cylindrical shank to DIN 6535‑HB with diameter tolerance h6. Recommended feed guidance for steels is 0.14 mm/rev at up to 800 N, which serves as a reference starting point for parameter optimisation; actual cutting data should be adjusted to machine rigidity, clamping and material batch. The cutter also centres solid carbide drills with 120–140° tip angles, allowing it to act as a reliable pre‑spotting tool in multi‑tool processes.

FAQ

What materials can this spot drill handle?
The TECWERK NC spot drill (NC spot drill 16 mm) is suitable for high‑strength steels, steel castings, grey cast iron, stainless steels and various non‑ferrous metals.

What is the recommended feed for steel applications?
A guideline feed for steel is 0.14 mm/rev at cutting forces up to 800 N; the feed for the NC spot drill should be adapted to machine stiffness and clamping conditions.

Can the tool prepare holes for subsequent solid carbide drills?
Yes, the centre geometry is intended to centre and chamfer holes for VHM drills with tip angles between 120° and 140°, enabling accurate follow‑up drilling.

What shank and tolerance specifications apply?
The shank is a cylindrical shank to DIN 6535‑HB with a diameter tolerance of h6, ensuring secure clamping and repeatable concentricity.

Why choose TiAlN coating for this application?
The TiAlN coating increases thermal resistance and wear stability, extending edge life during spotting and chamfering and improving consistent performance in mixed production tasks.
