NC spot drill D12 mm solid carbide 120° TECWERK

The NC spot drill D12 mm solid carbide 120° TECWERK is a purpose‑built tool for accurate position drilling and combined centring/chamfering on numerical control machines and boring mills, ideal for workshop and production environments where cycle time and repeatability matter.

• Solid carbide (VHM) construction
• Cylindrical shank to DIN 6535-HA
• 120° point for centring and chamfering
• Right‑hand cutting for reliable feeds
• Suitable for steels, cast iron and non‑ferrous

Higher throughput through precise, hardened construction

Manufactured from solid carbide, this spot drill delivers the rigidity and wear resistance required for repetitive NC operations. The 12 mm working diameter and 120° tip geometry translate into reliable initial engagement and reduced wander when positioning holes. With a cylindrical shank conforming to DIN 6535-HA, the tool seats consistently in standard fixtures and collets, supporting steady runs and minimising rework. These attributes combine to raise effective machine uptime while preserving hole quality.

Single‑pass centring and chamfering to save setup time

The geometry is optimised for simultaneous centring and chamfering, which eliminates an additional operation and reduces handling. The 120° tip produces a stable start for downstream threading or reaming, while the flute design evacuates chips efficiently during entry. The right‑hand cutting orientation ensures predictable chip flow and stable feed behaviour on conventional NC spindles. For workshops seeking to cut cycle time without compromising fit, this dual‑function approach offers an immediate efficiency gain.

Proven material compatibility and recommended cutting data

This tool is intended for a wide material spectrum including high‑strength steels, stainless steels and non‑ferrous metals, as well as cast and grey iron. The specified feed guidance—0.12 mm/rev in steel at clamping forces up to 800 N—serves as a practical starting point for production tuning; adjustments should follow standard machining best practice for workpiece hardness and fixturing. The combination of coating‑free solid carbide and robust geometry supports consistent performance across mixed batches.

Integration benefits for a reliable workshop workflow

Tolerance control to h6 on the working diameter and the standardised shank format reduce spindle runout and promote repeatable concentricity, important for subsequent threading or precision assembly. The tool’s construction simplifies inventory choices—one indexable‑free tool that replaces separate centring and chamfering steps—and facilitates predictable tool life planning. For procurement and process engineers, the reduced set‑up time and consistent hole quality deliver measurable gains in throughput and scrap reduction.
