TECWERK centre drill DIN 333 Form A, 4 mm — HSS, 60° tip

TECWERK centre drill engineered to produce accurate centre holes to DIN 332 for general machining and preparation for subsequent drilling operations

• DIN 333, Form A compliance
• High-speed steel for reliable wear resistance
• 60° tip angle for precise centre holes
• Feed 0.03 mm/rev in steel up to 800 N

Precision where it matters — accurate centring from first cut

The solid HSS construction and adherence to DIN 333, Form A ensure a consistently centred entry for subsequent drilling or turning operations. The 60° tip angle is tailored to produce a defined, repeatable centre recess in accordance with DIN 332 standards, reducing the risk of run-out and improving hole repeatability. This technical design translates into fewer reworks and more predictable downstream processes, particularly where concentricity is critical.

Controlled feed and material interaction for dependable results

Specified for general use and tested with feeds in steel, the tool performs with a recommended 0.03 mm/rev at steel conditions up to 800 N, promoting stable chip formation and minimised burr development. The given feed parameter provides a practical guideline for setting machine feed rates on lathes and drills; maintaining this value helps to preserve cutting edges and to achieve consistent centre geometry, which in turn supports accurate, efficient production workflows.

Standardised design for workshop efficiency and compatibility

Compliance with established norms means the tool integrates seamlessly into standard machining routines. The form and geometry are intended for producing centre holes without a protective countersink, allowing direct preparation to DIN 332 when that workflow is specified. The standardised form reduces set-up time and simplifies tool inventory, supporting faster changeovers and more reliable process planning across a range of components.

Practical advantages for everyday machining

As a general-purpose centring solution, the centre drill offers robustness and repeatability for routine workshop tasks. The combination of HSS material and standard geometry results in a tool that balances wear resistance with economical maintenance. For production managers and skilled tradespeople seeking predictable centring performance, this tool supports stable manufacturing sequences and contributes to overall process consistency.
