The combination of solid‑carbide construction, TiAlN coating and a 142° point angle ensures rapid, repeatable centring and chamfering with extended tool life; order the NC spot drill directly via Metav Werkzeuge or consult our specialists for application-specific advice.

NC spot drill D6 mm VHM TiAlN, 142° – TECWERK spot drill

The NC spot drill D6 mm VHM TiAlN 142° TECWERK is a solid‑carbide centre‑drilling tool optimised for precise, position‑accurate spot drilling and chamfering on NC machines and drilling rigs.

• Solid carbide VHM with TiAlN coating
• 142° point angle for accurate centring
• Cylindrical shank to DIN 6535‑HB
• Right‑hand cutting for NC machines
• Suitable for high‑strength steels and stainless

Consistent centring and chamfering in one pass

Engineered for efficient process integration, this spot drill delivers precise centring and simultaneous chamfering to reduce secondary operations. The solid‑carbide (VHM) substrate combined with a TiAlN coating improves heat resistance and wear behaviour, which translates into longer tool life under intermittent drilling conditions typical of NC machining. The generous 142° point angle provides a stable contact geometry, minimising walk‑off on hard or uneven surfaces and ensuring that holes start exactly where programmed.

Optimised for demanding materials and higher feeds

Designed for high‑performance use, the tool is particularly suitable for high‑strength steels, cast steel, grey cast iron, stainless steels and non‑ferrous metals. The technical design allows productive cutting data: recommended feed in steel up to 800 N is 0.09 mm/rev, balancing chip control and tool life. The TiAlN finish aids thermal stability at elevated cutting temperatures, permitting reliable operation on tougher alloys without premature coating failure or rapid flank wear.

Machine compatibility and simple integration

The cylindrical shank to DIN 6535‑HB ensures secure clamping in standard toolholders and quick change systems, facilitating smooth integration into existing NC set‑ups and drilling rigs. Right‑hand cutting geometry suits conventional spindle rotation and common machining cycles. For workshops seeking reduced set‑up times, the ability to centre and countersink in a single operation shortens cycle times and lowers the cumulative risk of misalignment during multi‑stage procedures.

Process reliability and application guidance

For position‑sensitive drilling tasks the spot drill supports accurate preparation of threaded holes and subsequent twist drills with 120–140° point angles, enabling repeatable, centred starts. The combination of tool geometry and coating reduces the need for frequent rework and inspection, contributing to stable part quality and predictable process windows. When selecting cutting parameters for a specific component batch, consider material condition and clamping stiffness to exploit the drill’s strength without overstressing the holder assembly.

FAQ

What materials can this spot drill handle? The NC spot drill D6 mm VHM TiAlN 142° is suited for high‑strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals, as stated in the technical specification.

Is the shank compatible with standard toolholders? Yes, the tool features a cylindrical shank to DIN 6535‑HB, ensuring compatibility with conventional collets and hydraulic chucks used in NC machines and drilling rigs.

Can this drill be used for preparing threaded holes? The spot drill is designed for centring and chamfering in a single operation, making it ideal for preparing threaded hole starts and improving subsequent thread‑tap or twist‑drill guidance.

What cutting data should be used as a starting point? A recommended feed in steel up to 800 N is 0.09 mm/rev; adjust feed and spindle speed according to material condition and clamping rigidity for optimal life.

Does the TiAlN coating improve tool life at higher temperatures? Yes, the TiAlN coating increases thermal resistance and reduces wear at elevated cutting temperatures, contributing to longer service life compared with uncoated tools.
