NC spot drill D 4 mm HSS‑Co, 90° – TECWERK

The NC spot drill D 4 mm HSS‑Co is a right‑hand cutting centre tool designed for position‑accurate and rapid spot‑drilling and chamfering on NC machines and drill rigs.

• HSS‑Co for increased heat resistance
• DIN 1835‑A cylindrical shank
• 90° point for precise centring

Accurate starting and reduced wandering for machining cycles

The 90° tip geometry ensures dependable initial engagement, reducing the tendency to “walk” before the main drill enters the workpiece. Manufactured from HSS‑Co, the tool keeps its cutting edge under elevated thermal loads, which yields more consistent hole starts and fewer rework cycles. For automated production this means shorter cycle times and improved first‑pass accuracy during hole preparation on NC machines and conventional drill rigs.

Robust design for continuous operation

With a DIN 1835‑A cylindrical shank the tool integrates cleanly with standard holders, simplifying set‑up and tool changes. The right‑hand cutting geometry and cobalt‑alloyed high‑speed steel provide greater wear resistance compared with standard HSS, supporting longer tool life in repetitive operations. These construction choices combine to reduce downtime and contribute to steadier output quality across demanding production runs.

One‑pass centring and chamfering to save process steps

This centre drill was designed to both centre and chamfer thread holes in a single operation, removing the need for a separate chamfering step. The integrated chamfering capability stabilises subsequent tapping or drilling operations and helps achieve a clean, repeatable entry for thread formers and taps. By consolidating operations, the centre tool minimises handling, shortens overall process chains and supports leaner workflow set‑ups.

Process guidance for reliable feed control

A specified feed guideline of 0.03 mm/rev at steel loads up to 800 N gives a concrete starting point for process parameters; this helps to align machine settings with the tool’s intended performance envelope. Operators should match spindle speed and feed to the workpiece material and fixturing quality to maintain hole accuracy. For integration into CNC routines, the combination of the tool’s geometry and the fixed DIN 1835‑A interface allows predictable, repeatable results across batches.

FAQ

What is the primary use of this centre tool?
The NC spot drill D 4 mm HSS‑Co is intended for position‑accurate spot‑drilling and for centring and chamfering thread holes in a single pass on NC machines and drill rigs.

Which shank interface does the tool use?
The tool features a DIN 1835‑A cylindrical shank, ensuring compatibility with standard tool holders and straightforward integration into existing setups.

What material is the tool made from and why is that important?
Constructed from HSS‑Co, the drill offers improved heat and wear resistance compared with standard high‑speed steel, which supports longer service life in automated production.

What feed should be used for steel applications?
A guideline of 0.03 mm/rev is provided for steel with loads up to 800 N; this figure helps to set initial feed rates for reliable hole starts and consistent chamfering.

Can the tool replace a separate chamfering operation?
Yes. The integrated chamfering geometry allows centring and chamfering in one operation, reducing process steps and handling.
