Centre drill DIN 333 Form A Ø 2.5 mm HSS, 60° — TECWERK

The Centre drill DIN 333 Form A Ø 2.5 mm HSS is a precision centre-drilling bit for creating standard centre holes to DIN 332 in general workshop and industrial applications.

• High-speed steel construction
• DIN 333 Form A geometry
• 60° tip for standard centre holes
• Suitable for general workshop use

Precision and consistent centring for reliable downstream drilling

Made from HSS, the tool delivers a hard-wearing cutting edge that balances toughness with edge retention, so thread and drill starts remain consistent across repeated operations. The DIN 333 Form A profile combined with a 60° tip angle produces the correct seat for subsequent drilling and turning operations, reducing run-out and rework. With a nominal diameter of 2.5 mm and an overall length of 45 mm, the tool fits standard toolholders and offers controlled chip evacuation. Recommended feed when machining steel up to 800 N is 0.03 mm/rev, which supports stable entry without excessive forces and helps maintain tool life.

Designed for routine workshop use with clear technical advantages

The geometry is optimised for general-purpose centre drilling: the form ensures the hole meets the tolerances required by DIN 332 without a protective countersink, making the tool suitable for preparatory centring before larger drills or lathe turning operations. The right-hand cutting direction promotes predictable chip flow on most bench and machine setups. Supplied in a pack of 5, the set-up frequency is reduced and replacement is straightforward, limiting machine downtime. The compact design and standardised dimensions simplify inventory control for maintenance teams and small-batch production.

Practical benefits for procurement and everyday handling

Because the tool adheres to established standards and utilises HSS construction, purchasing and process planning become more predictable: the tool’s specification aligns with common workshop practices and supports reliable supply chains. The short overall length and small diameter reduce the risk of deflection in normal centring tasks, while the documented tip angle assists process engineers when specifying entry parameters. The combination of standard conformity and robust material choice contributes to long-term consistency in hole quality, lowering scrap rates and supporting cost-efficient operations.
