NC spot drill D12 mm, solid carbide, TiAlN coating — TECWERK

A NC spot drill D12 mm designed for position-accurate starting holes and simultaneous chamfering on NC machines and boring mills

• Solid carbide construction VHM
• TiAlN hard-wearing coating
• DIN 6535-HA cylindrical shank
• 90° point for reliable centring

Accurate starts and efficient thread preparation

The combination of solid carbide geometry and a 90° point provides a reliable centre and countersink in a single pass, reducing setup time and minimising repositioning. This starter cutter creates a precise entry that stabilises subsequent twist drills and taps, lowering the risk of runout and broken tools. The integrated chamfering action improves thread engagement and reduces rework, which is especially valuable in medium- to high-volume production environments where repeatable hole quality is essential.

Wear resistance for demanding materials

A TiAlN surface finish increases thermal and abrasive resistance, extending tool life under elevated cutting temperatures. The coating is particularly beneficial when working with high-strength steels and stainless steels, as well as cast and non-ferrous materials, helping to maintain cutting geometry and preserve tolerances over longer runs. This results in fewer tool changes, more predictable batch throughput and a demonstrable improvement in process economy.

Machine compatibility and measurable performance

Equipped with a DIN 6535-HA cylindrical shank and a tight h6 tolerance, the tool is tailored for automatic toolholders and spindle systems on modern NC machines and boring mills. The tool’s dimensions—12 mm diameter, 70 mm overall length and 24 mm spiral length—support stable clamping and sufficient engagement. The specified feed recommendation of 0.12 mm/rev in steel (up to 800 N) offers a reliable starting point for programming and reduces the need for trial-and-error adjustments.

Practical guidance for reliable results

For best outcomes, secure the cylindrical shank in a compliant holder per machine manufacturer guidance and use the recommended feed for the material class. The right-hand cutting geometry and the starter profile make this cutter suitable for quick, position-accurate drilling cycles and combined centring/chamfering operations. When replacing worn tools, inspect the TiAlN layer and the point geometry to ensure continued precision and consistent hole quality.

FAQ

What materials can this spot drill handle?
The TECWERK NC spot drill is suitable for high-strength steels, stainless steels, cast iron and a range of non-ferrous metals, owing to its solid carbide body and TiAlN coating.

Is the shank compatible with automatic toolholders?
Yes, the tool has a DIN 6535-HA cylindrical shank with h6 tolerance, making it compatible with standard holders and automatic toolchanging systems.

What feed should be used for steel?
A recommended reference is 0.12 mm/rev in steel up to 800 N, which balances cutting forces and tool life for the starter operation.

Can this drill centre and chamfer in a single operation?
The geometry is designed to centre and chamfer threaded holes in one pass, reducing cycle time and improving positional accuracy.
