TECWERK centre drill DIN 333, Form A — 8 mm HSS, right-hand

A centre drill DIN 333 Form A, 8 mm HSS (right-hand) designed for producing precise centre holes to DIN 332 in general workshop and steel-working applications

• HSS material for durability and wear resistance
• 60° centring tip for consistent hole geometry
• Conforms to DIN 333 Form A standard

Reliable starts improve drilling accuracy and reduce runout

The split between pilot and countersink in this centre drill gives a defined entry point that stabilises subsequent machining operations. The 8 mm diameter and 60° tip produce a clean centre hole in accordance with DIN 332, which reduces the risk of spindle runout and misalignment when reaming or drilling follow-up holes. The main benefit is improved positional accuracy, which shortens set-up times and reduces scrap rates in series and single-part production.

Durable HSS body for extended tool life in general use

Manufactured from HSS, this centre drill offers a balance between toughness and hardness that suits a wide range of workshop tasks. The material choice supports steady wear characteristics and resistance to chipping during interrupted cuts. For operations involving moderate cutting forces, the tool’s construction delivers reliable repeatability and lowers the frequency of tool changes — a direct efficiency gain for production workflows without sacrificing finish quality.

Defined feed parameters for controlled machining performance

Specified feed guidance — 0.06 mm/rev in steel up to 800 N — provides a practical benchmark for setting machine parameters, ensuring stable chip formation and consistent centring results. Following this recommendation helps to avoid burr formation while maintaining adequate material engagement for the pilot to seat correctly. The conformity to DIN 333 Form A also simplifies process documentation and quality assurance, enabling predictable outcomes across batches and machines.
