NC Spot Drill D 3 mm – HSS‑Co, TiN, 90° by TECWERK

The NC Spot Drill D 3 mm is a cobalt high‑speed steel centre/spot drill with a TiN coating, engineered for accurate positioning and simultaneous centring and chamfering of tapped holes on NC machines and drilling centres.

*HSS‑Co for elevated heat resistance *TiN coating for prolonged tool life *Cylindrical shank to DIN 1835‑A *Centring and chamfering in one pass

Consistent positioning and machine integration

The combination of HSS‑Co construction and a TiN surface treatment delivers a tool that resists thermal softening while maintaining sharpness at speed. The 90° tip geometry ensures reliable initial contact for spot drilling and countersinking, reducing walk‑off on the workpiece. A cylindrical shank to DIN 1835‑A provides standardised seating in holders and chucks, so the tool integrates directly into common NC tool systems and drilling centres without adaption. These characteristics create a predictable baseline for process planning and tool‑change routines.

Reduced cycle time through dual‑function machining

Designed for positional and rapid anbohren (spot drilling) on NC equipment, the tool enables centring and chamfering of threaded holes in a single operation, which shortens cycle time and minimises handling. The specified feed behaviour—0.03 mm/rev in steel up to 800 N—supports repeatable entry conditions and consistent hole starts, improving thread alignment and tapping reliability. The right‑hand cutting orientation maintains conventional chip flow for standard spindle directions, further enhancing throughput in typical CNC workflows.

Material performance and service life

This spot drill is tailored for machining steel, where the documented feed parameter applies; the HSS‑Co substrate offers elevated red hardness and toughness compared with standard high‑speed steels, while the TiN coating lowers friction and increases wear resistance. Together these traits extend tool life under demanding, high‑temperature entry conditions and support a stable surface finish at the hole entry. Clear, measurable tool behaviour simplifies maintenance intervals and tool‑change planning in production environments.

Practical fit‑up and operational advice

Compatibility with DIN 1835‑A holders makes mounting straightforward and repeatable; the tool is right‑hand cutting and intended for use in NC machines and drilling centres. For best results, adhere to the stated feed parameter when working in comparable steel conditions and ensure correct seating in the tool holder to avoid run‑out. The construction and coating prioritise longevity and process reliability, making the tool suitable for series production where predictable starts and chamfers are required.

FAQ

What is the primary application for this spot drill?
The NC Spot Drill D 3 mm (TECWERK, SKU 2000861383NW) is intended for positional spot drilling and simultaneous centring and chamfering of tapped holes on NC machines and drilling centres.

Which materials is the tool designed to machine?
The tool is specified for steel applications — the feed parameter of 0.03 mm/rev applies in steel conditions up to 800 N, as stated for the NC Spot Drill D 3 mm by TECWERK.

How does the TiN coating affect performance?
The TiN coating on the TECWERK spot drill reduces friction at the cutting edge and increases wear resistance, which contributes to longer service life and more consistent hole starts under typical NC operating conditions.

Is the shank compatible with standard holders?
Yes — the cylindrical shank conforms to DIN 1835‑A, ensuring compatibility with standard holders and chucks used on NC machines and drilling centres.
