TECWERK NC spot drill D12 mm — solid carbide centre drill, 90°

The TECWERK NC spot drill D12 mm is a solid carbide centre drill designed for positions-accurate and rapid spot drilling, centring and countersinking in a single pass on NC machines and drilling centres.

• Solid carbide construction (VHM)
• Cylinder shank to DIN 6535-HA
• 90° tip for precise positioning and centring
• Suitable for high-strength steels and stainless steel

Accurate positioning that speeds up cycle times

The combination of solid carbide material and a 90° tip provides a stable, wear-resistant working edge that keeps initial holes true and concentric. As a result, toolpaths are shorter and setup time is reduced, which improves throughput on repetitive operations. The geometry enables reliable centring and countersinking in one operation, lowering the number of tool changes and the risk of misalignment during subsequent threading or drilling steps.

Reliable clamping and machine compatibility

A cylinder shank manufactured to DIN 6535-HA ensures consistent clamping concentricity in collets and holders commonly used on CNC lathes, machining centres and drilling machines. The standardised shank format simplifies tool management and reduces runout, which translates into more predictable hole quality and fewer rejects. The tool is configured for conventional NC toolholding systems, aiding rapid installation and repeatable performance.

Broad material suitability with clear machining guidance

The spot drill is optimised for machining a wide range of materials, including high-strength steels, steel castings, grey cast iron, stainless steels and non‑ferrous metals. For steel up to 800 N the recommended feed is 0.12 mm/rev, which balances hole definition and tool life under typical spot‑drilling loads. The tool’s right‑hand cutting direction matches standard spindle rotation, delivering efficient chip formation and secure entry into the workpiece.

Practical advantages for workshop workflows

By combining centring and countersinking in a single pass the tool reduces handling and cycle complexity, which supports shorter lead times and lower rework rates. The robust carbide construction helps maintain tip integrity across extended batches, contributing to predictable maintenance intervals and less unscheduled downtime. For operations requiring repeatable hole start quality, the tool supports consistent thread preparation and better downstream tapping results.
