TECWERK centre drill DIN 333 Form A, 2.5 mm HSS, 60°

A TECWERK centre drill DIN 333 Form A engineered for accurate production of centring holes to DIN 332 standards in general machining applications.

• HSS material for long tool life
• DIN 333 Form A standard geometry
• 60° centring angle for DIN 332 centres
• Feed in steel up to 800 N: 0.03 mm/rev

Enhanced process reliability through standardised geometry

The combination of DIN 333 Form A geometry and a 60° centring angle ensures consistent, repeatable centre holes that match DIN 332 requirements. This standardised shape reduces wobble and improves concentricity at the first operation, which shortens downstream alignment steps and minimises scrap. The HSS substrate provides toughness for intermittent drilling tasks and lowers the risk of brittle fracture compared with harder, more brittle grades.

Clear cutting parameters for predictable performance

Specified feed behaviour—0.03 mm/rev in steel up to 800 N—permits reliable cycle-time planning and tool-life estimation. Stating the feed as a function of force helps production engineers assess compatibility with existing spindles and feed drives. The drill’s design for producing centre holes without a protective countersink simplifies workflow when a dedicated countersink is unnecessary, saving one machining step while maintaining secure workpiece support for subsequent turning or drilling.

Versatile use across general machining tasks

Designed as a general-purpose centring tool, the bit adapts well to manual lathes, CNC turning centres and conventional drill heads. The HSS construction balances wear resistance with edge toughness, making it suited to a range of common workshop materials. Its straightforward geometry makes it a dependable tool for preparatory centre holes or for use before transfer to more specialised tools, reducing fixturing time and improving throughput.

Practical benefits for workshop efficiency

Choosing a standardised centre drill reduces setup variability and supports predictable downstream accuracy, which benefits batch production and one-off projects alike. The compact diameter and robust substrate allow precise positioning without excessive material removal, thereby preserving component integrity and reducing the need for rework. Clear technical data facilitates rapid QA checks and integration into tooling lists for maintenance planning.
