8mm Solid Carbide NC Spot Drill TiAlN Coated 142° Point, Cylinder Shank DIN 6535-HB, Right-Handed - TECWERK

Benefit from a combination of solid carbide construction and a TiAlN surface for reliable centring and extended tool life; the 142° point enables precise spot drilling and single-pass chamfering. Order the NC spot drill directly via Metav Werkzeuge or ask our consultants if needed.

NC Spot Drill D.8mm VHM TiAlN 142° — TECWERK, solid carbide spot drill with TiAlN coating

The NC Spot Drill D.8mm VHM TiAlN 142° TECWERK is a purpose-built spot drill for precise, position-accurate centre drilling and chamfering on NC machines and drilling centres.

• Solid carbide (VHM) construction
• TiAlN coating for high temperature resistance
• 142° point for precise centring and chamfering
• Cylindrical shank to DIN 6535‑HB

Faster setup and fewer tool changes for higher throughput

The combination of solid carbide body and a blunt 142° point delivers a stable, repeatable starting hole that reduces run-in and tool wandering. This stability translates into faster cycle times because centring and chamfering can be completed in one operation, eliminating an extra tool change. For production environments and job shops the practical benefit is clear: fewer operations per hole and reduced rework, which supports smoother workflows on NC machines and drilling centres.

Heat resistance and consistent wear performance

A TiAlN coating increases surface hardness and thermal stability at the cutting edge, which reduces adhesion and oxidation under elevated temperatures. The result is longer tool life and more consistent hole quality when machining demanding materials such as high-strength steels, stainless steels and cast irons. Recommended feed in steel up to 800 N is 0.1 mm/rev, providing a practical guideline to balance cutting forces and surface finish while maintaining tool integrity.

Built for compatibility and practical on-machine use

The tool features a cylindrical shank to DIN 6535‑HB, ensuring compatibility with standard tool holders and chucks used in industrial machining. Its geometry is optimised for right-hand cutting and for centring solid carbide drills with point angles between 120° and 140°, allowing this spot drill to serve as a reliable pilot for follow-up drills and taps. The integrated chamfering capability simplifies thread preparation by creating a clean lead-in for taps, which reduces tap breakage and improves first-pass thread quality.

FAQ

Which materials are suitable for this spot drill?
The NC Spot Drill D.8mm VHM TiAlN 142° TECWERK is specified for high-strength steels, cast steel, grey cast iron, stainless steels and various non‑ferrous metals.

What point angle does the tool use and why is that important?
The tool has a 142° point, which combines accurate centring with a small chamfer—this reduces drill walking and prepares a chamfer suitable for tapping in one operation.

How should feed be set for steel applications?
A practical guideline for steel under cutting forces up to 800 N is 0.1 mm/rev, balancing surface finish and tool life for the TECWERK spot drill.

Is the shank compatible with standard holders?
Yes. The tool uses a cylindrical shank to DIN 6535‑HB, ensuring compatibility with common chucks and collets on machining centres.
