Take advantage of the combination of solid carbide construction, TiAlN surface treatment and a 90° centring point for fast, positionally accurate spotting and chamfering on NC machines; order the tool directly via Metav Werkzeuge or consult the Metav team for application advice.

NC spot drill D.4mm solid carbide TiAlN 90° TECWERK

The NC spot drill D.4mm VHM TiAlN 90° TECWERK is a precision centre‑drilling tool for positionally accurate spotting, centring and chamfering on NC machines and drilling centres.

• Solid carbide with TiAlN coating
• 90° point for accurate centring
• Cylindrical shank to DIN 6535-HA

Faster, more reliable positioning on CNC and NC equipment

The combination of a solid carbide body and a TiAlN coating delivers high rigidity and improved heat resistance, which translates into consistent, repeatable spotting operations on modern CNC machines. The 90° point ensures fast and accurate centring before subsequent drilling or tapping; this reduces setup time and minimises rework. Designed for short-cycle production, the tool maintains positional integrity even under frequent use, helping to improve throughput without compromising hole quality.

One‑pass centring and chamfering to streamline workflow

With a geometry optimised for simultaneous centring and bevel formation, the spot drill removes the need for separate chamfering operations. The cylindrical shank to DIN 6535‑HA guarantees secure clamping in standard toolholders, while the short flute length allows precise control during entry. For operations that demand quick cycle times and repeatability, this approach reduces handling steps and contributes to a more efficient production flow.

Engineered for demanding materials and stable feeds

The tool is particularly suitable for high‑strength steels, cast steel, grey cast iron, stainless steels and non‑ferrous metals. The substrate and coating combination withstands elevated temperatures and abrasion in these materials, enabling a recommended feed of 0.06 mm/rev in steel at cutting forces up to 800 N. The right‑hand cutting action and controlled flute geometry help evacuate chips reliably, minimising the risk of built‑up edge and preserving hole integrity.

Precision fit and repeatable tolerances for batch production

A diameter tolerance of h6 ensures a consistent fit and repeatable centre positions across multiple components. The tool’s overall length and flute dimensions are balanced for rigidity and access: the overall length 50 mm with a spiral (flute) length 12 mm provides the necessary reach while keeping deflection low. These factors combine to deliver measurable accuracy gains in batch and serial manufacturing, supporting quality control and reducing scrap rates.

FAQ

What materials is the NC spot drill suitable for?
The NC spot drill D.4mm VHM TiAlN 90° TECWERK is suitable for high‑strength steels, cast steel, grey cast iron, stainless steels and various non‑ferrous metals.

How does the TiAlN coating benefit the tool performance?
The TiAlN coating on the TECWERK spot drill increases thermal resistance and reduces wear, extending tool life and maintaining consistent centring quality under elevated cutting temperatures.

What tolerance and shank standard does the tool use?
The tool is manufactured with a diameter tolerance of h6 and a cylindrical shank conforming to DIN 6535‑HA for secure clamping and repeatable positioning.

Can the tool perform chamfering and centring in a single operation?
Yes, the geometry of the TECWERK NC spot drill enables precise centring and simultaneous chamfering of threaded holes in one pass, lowering cycle count.

What spindle feed is recommended for steel applications?
A feed of approximately 0.06 mm per revolution is indicated for steel at cutting forces up to 800 N when using this spot drill.
