Centre drill DIN 333 Form R Ø2.5 mm HSS, right-hand — TECWERK

A Centre drill DIN 333 Form R Ø2.5 mm HSS, right-hand — TECWERK engineered to produce precise centring holes with a 60° chamfer for general workshop and production use

• HSS construction, DIN 333 Form R
• Right-hand cutting geometry
• 60° countersink angle for DIN 332 holes
• Feed 0.03 mm/rev in steel up to 800 N

Accurate starts that reduce rework

The centre drill adopts the DIN 333 Form R profile to create a reliable start for subsequent drilling or turning operations. The Form R geometry, which includes a small radius, stabilises the initial contact and reduces the risk of walk or misalignment. By providing a defined entry with a 60° chamfer, the tool improves concentricity of follow-up operations and minimises rework, saving machine time and improving first-pass yield.

Cutting geometry for consistent hole formation

Equipped with right-hand cutting geometry and manufactured from HSS, the tool balances sharpness and toughness for predictable chip formation. The specified feed of 0.03 mm/rev in steel up to 800 N indicates typical operating conditions for a steady process; this measurable parameter helps set machining cycles and optimises tool life. The centring profile meets the requirements for holes to DIN 332 sheet 1 Form R, facilitating standard-compliant production.

Robust material and workshop versatility

Made from HSS, the centring tool delivers a combination of wear resistance and ease of resharpening that suits a broad range of routine applications. The material choice supports sustained edge integrity during frequent starts and short plunges, making the tool a pragmatic choice for workshops seeking dependable consumables. Its construction translates into fewer tool changes and lower downtime across everyday tasks.

Easy process integration and handling benefits

With a nominal diameter of 2.5 mm, the centre drill fits common tooling assemblies and chucks used in standard machining centres and bench drills. The clear technical specification and conformity to recognised standards simplify process planning and inventory management. By reducing ambiguity about hole form and entry angle, the tool contributes to reproducible setups and predictable part quality, supporting continuous production demands.
