TECWERK centre drill DIN 333 Form B, 2.5 mm — HSS with protective countersink

A TECWERK centre drill DIN 333 Form B 2.5 mm designed for producing centring holes per DIN 332 sheet 1 with an integrated protective countersink, suitable for general workshop and industrial use

• HSS construction for long tool life
• DIN 333 Form B geometry
• Integrated protective countersink 60/120°
• Right-hand cutting, 0.03 mm/rev in steel

Accurate centring to reduce tool walk and rework

The centre drill follows DIN 333, a proven geometry for producing reliable starting holes that prevent drift when subsequent drills engage. By combining a rigid shank geometry with a protective countersink, the tool reduces burr formation and minimises the need for secondary operations. This leads to fewer scrapped parts and steadier repeatability in batch production — a direct benefit to workshop throughput and process reliability.

Hard-wearing high-speed steel and defined cutting data for consistent results

Constructed from HSS and configured for right-hand cutting, the bit is optimised for durability and predictable wear behaviour. The dual countersink angles of 60/120° enable a controlled entry and a defined conical seat, while the specified feed of 0.03 mm/rev in steel up to 800 N supports steady material removal without overloading the tool. These measurable parameters allow planners to integrate the bit into existing machining cycles with minimal trial-and-error.

Simple standard compliance that eases process planning

Compliance with the centring specification in DIN 332 sheet 1 Form B means an immediately recognisable standard for toolrooms and production engineers. The standardised geometry enables interchangeability across fixtures and machines and simplifies incoming goods inspection. Where process documentation or capability studies are required, the standard reference removes ambiguity and supports quality management procedures.

Designed for workshop efficiency and lower follow-up costs

The integrated protective countersink and robust geometry result in fewer burrs and reduced manual deburring effort. The tool suits a range of general workshop tasks where reliable centring is essential before longer drills or turning operations. For technical queries regarding specific applications or material regimes, the supplier’s advisory service can provide guidance tailored to particular production conditions and machine tool characteristics.

FAQ

What is this tool intended for?
The TECWERK centre drill DIN 333 Form B is intended for producing precise centring holes and a defined countersink to support subsequent drilling and machining operations.

Which materials can be machined with this centre drill?
The centre drill, made from HSS, is specified for general use on steels (up to 800 N) and other common workshop materials compatible with HSS tooling.

What are the countersink angles and why do they matter?
The tool features 60/120° countersink angles; the combination ensures a controlled entry and a stable conical seat, reducing burrs and improving the concentricity of subsequent drills.

What feed should be used for centring in steel?
A recommended feed for centring in steel up to 800 N is 0.03 mm/rev, which balances material removal and tool life for consistent results.

Is the cutting direction right-hand or left-hand?
The centre drill is configured for right-hand cutting, matching the standard rotation direction of most workshop drilling and lathe equipment.
