TECWERK centre drill DIN 333 Form A, HSS‑Co, Ø 2.5 mm

A TECWERK centre drill DIN 333 Form A for accurate centring and reliable pilot holes in demanding workshop and production environments.

• HSS-Co high-speed steel
• DIN 333 Form A centre drill
• 60° countersink angle for precise centring
• For >800 N/mm² and CrNi steels

Precision where strength matters

The combination of HSS‑Co construction and the DIN 333 Form A geometry ensures consistent centring performance in tough materials. The tool is intended for producing centre holes to DIN 332 without protective countersink, which reduces set‑up variance and improves repeatability. With a nominal tip of Ø 2.5 mm and a total length of 45 mm, the design balances rigidity and access for typical lathe and drilling‑machine set‑ups, making it suited for series production as well as repair tasks.

Design features that simplify machining

The integral shank with Shank Ø 6.3 mm and the right‑hand cutting geometry support secure clamping and conventional spindle rotation, while the 60° countersink angle creates a defined entry for subsequent drills or centres. The absence of a protective countersink reduces tool overhang and helps maintain concentricity; this simplified form lowers the risk of chatter and makes clamping checks straightforward, improving process stability on small to medium batches.

Productivity data and recommended operation

For machining in steel up to 800 N, a recommended feed of 0.03 mm/rev is given, delivering controlled chip formation and consistent hole geometry. The tool is specified for materials with tensile strength above 800 N/mm² and for corrosion‑, acid‑ and heat‑resistant CrNi steels; this capability translates into fewer tool changes and a steadier production flow. The compact overall length and proven geometry reduce rework, supporting lean workflows in metalworking shops and subcontracting environments.
