NC spotting drill D6 mm — solid carbide, TiAlN coating, 142° — TECWERK

The NC spotting drill D6 mm is a TiAlN‑coated solid‑carbide centre drill for accurate, position‑stable pilot drilling and simultaneous chamfering on NC machines and drilling centres.

• Solid carbide body with TiAlN coating
• 142° point angle for exact centring
• Cylindrical shank to DIN 6535‑HB tolerance h6
• Suitable for high‑strength and stainless steels

Precision where it counts for downstream processes

The spotting drill delivers consistent centre positions that reduce runout and rework. The combination of a 142° point angle and a stiff solid‑carbide body enables reliable centring for subsequent twist drills and taps, so hole geometry is preserved through the machining sequence. For automated NC production, this means fewer rejected parts and more predictable cycle times, improving overall process reliability.

Longer tool life and thermal stability under load

The TiAlN coating increases heat resistance and wear protection at elevated temperatures, which is especially beneficial when machining tough alloys. The carbide core provides stiffness and resistance to chipping, so edge geometry remains intact over longer tool life. In practice, this translates to extended service intervals and reduced tool change frequency on high‑duty production runs.

Designed for efficient NC workflows and exact single‑pass operations

With a cylindrical shank to DIN 6535‑HB and h6 tolerance, the shank seats precisely in collets and holders, reducing concentricity errors. The right‑hand cutting geometry and designated feed recommendation of 0.09 mm/rev in steel (up to 800 N) support predictable material removal rates. The tool centres and chamfers tapped holes in one pass, accelerating set‑ups on both NC milling machines and drilling centres and simplifying programme design.

Broad material compatibility and practical application notes

This centre drill is intended for demanding substrates: high‑strength steels, steel castings, grey cast iron, stainless steels and various non‑ferrous metals. Its geometry also suits the centring of solid‑carbide twist drills with point angles between 120° and 140°, enabling matched tool chains. The result is a versatile pilot‑drilling solution that reduces manual realignment and supports high‑precision production environments.

For reliable, production‑grade centring and chamfering choose the TECWERK NC spotting drill and contact Metav Werkzeuge in Emmerich for availability, stocking options and supply coordination.

FAQ

Is this spotting drill suitable for stainless steel?
Yes. The TECWERK NC spotting drill D6 mm is specifically listed for stainless steels and retains edge stability due to its solid‑carbide body and TiAlN coating.

Can the tool be used to both centre and chamfer in a single operation?
Yes. The 142° point angle and geometry allow centring and light chamfering in one pass, reducing cycle steps when preparing tapped holes.

Which shank standard ensures accurate clamping?
The tool is supplied with a cylindrical shank to DIN 6535‑HB and h6 tolerance to ensure tight, repeatable seating in collets and holders.

What feed is recommended for steel applications?
A reference feed of 0.09 mm/rev in steel up to 800 N is provided for controlled penetration and tool life; adjust according to machine rigidity and material condition.

Can it be used to centre solid‑carbide twist drills?
Yes. The spotting drill is suitable for centring solid‑carbide twist drills with point angles between 120° and 140°, supporting matched drilling tool chains.
