TECWERK NC spot drill D12 mm — solid‑carbide, TiAlN, 142°

The TECWERK NC spot drill D12 mm is a solid‑carbide, TiAlN‑coated centre tool designed for position‑accurate spotting, centring and chamfering on NC machines and drilling centres.

• Solid carbide (VHM) with TiAlN coating
• 142° point angle for accurate centring
• Cylindrical shank to DIN 6535‑HB
• Suitable for high‑strength steels and stainless

Precise centring and faster set‑up for production

The combination of a 142° point angle and solid‑carbide construction delivers highly repeatable centring, so holes start exactly where programmed. This enables secure guidance for subsequent drills and reduces rework from misaligned starts. The tool’s ability to perform centring and chamfering in a single pass shortens cycle times on NC machines and drilling centres, improving throughput without compromising hole quality.

Durable coating and material compatibility

A TiAlN coating increases surface hardness and oxidation resistance at elevated temperatures, making the tool resilient during prolonged operations. The solid‑carbide substrate provides stiffness and vibration resistance for consistent performance. The tool is particularly suited to high‑strength steels, cast steel and grey cast iron, as well as stainless steels and non‑ferrous metals, offering a reliable option when working with demanding materials.

Practical machining data for reliable results

Designed with a cylindrical shank to DIN 6535‑HB, the spot drill fits standard toolholders for NC machining centres and drill rigs, simplifying integration into existing setups. For feeds in steel up to 800 N, a guideline feed of 0.12 mm/rev supports efficient material removal while maintaining hole integrity. The tool’s right‑hand cutting geometry ensures conventional machining direction and consistent chip formation.

One‑tool workflow and tool pairing

Because the tool centres solid‑carbide drills with a 120–140° point angle, it supports accurate pre‑positioning for subsequent drilling operations, reducing the need for multiple tools or separate chamfering passes. The single‑operation approach reduces handling, minimises clamping errors and helps maintain a predictable production rhythm — a practical benefit for series production and small‑batch NC jobs.
