TECWERK NC centre drill D10 mm, HSS‑Co, 120° tip

A NC centre drill D10 mm HSS‑Co 120° TECWERK for position‑accurate spot drilling, centring and chamfering on NC machines and drill rigs.

• HSS‑Co high-speed cobalt construction
• DIN 1835‑A cylindrical shank
• 120° centring tip for precise starts

Reliable centring for repeatable production starts

The HSS‑Co composition delivers elevated hot‑hardness and wear resistance compared with standard high‑speed steels, which keeps the cutting edge sharper for longer in serial production. With a DIN 1835‑A interface, the tool fits industry‑standard toolholders without adapters, ensuring stable clamping and repeatable runout values. The combination of material and shank standard reduces tool change time and contributes to consistent hole positioning, supporting a steady production flow with fewer rejects.

Faster process with combined centring and chamfering

A 120° tip geometry provides a reliable centre and a light chamfer in a single operation, eliminating a separate deburring pass for many threaded bores. The tool is specified for a recommended feed in steel up to 800 N of 0.09 mm/rev, a datum that helps set machining parameters for efficient chip formation and surface quality. By merging centring and chamfering, the centre drill shortens cycle time and lowers handling, which in turn improves throughput on NC lathes and drilling rigs.

Integration and handling for production environments

The tool is right‑hand cutting and supplied with a cylindrical shank to DIN 1835‑A for direct mounting in commonly used spindles and toolholders. The diameter tolerance h8 ensures precise fitment for repeatable positioning in fixtures. Designed specifically for NC machines and drill rigs, this centre drill supports process stability and minimal setup effort, making it a practical choice for workshops seeking dependable starts without complex tooling changes.
