Centre drill DIN 333 Form R Ø 3.15 mm HSS, right-hand cutting — TECWERK

A Centre drill DIN 333 Form R Ø 3.15 mm HSS designed for producing standard centre holes with a 60° countersink and radius tip for general workshop applications

• HSS construction for long tool life
• DIN 333 Form R for radius-type centring
• 60° countersink angle for standard centre holes
• Feed 0.03 mm/rev in steel up to 800 N

Accurate centring for repeatable machining set-ups

The HSS body combined with the DIN 333 radius geometry delivers a stable initial bore that positions subsequent drills and lathes with confidence. The 3.15 mm diameter and a 60° countersink match common lathe and turning centre specifications, reducing the need for secondary alignment steps. By producing a defined centre recess, the tool reduces run-out on long workpieces and supports consistent part quality across small to medium production runs.

Controlled cutting behaviour and material handling

Right-hand cutting geometry and a defined feed recommendation—0.03 mm/rev in steel up to 800 N—ensure predictable chip formation during centring operations. The radius point (Form R) minimises splitting in softer materials while maintaining a clear entry in harder stock, so the centring tool copes with a variety of shop-floor materials without complex parameter changes. The simplified feed guidance aids machinists and programmers in selecting initial spindle speeds and feeds for safe, repeatable starts.

Practical workshop integration and durability

The centring tool is compatible with standard drill holders and tailstock set-ups, enabling quick insertion into existing workflows. The hardened cutting geometry of the shank and pilot section supports robust seating and extended service life under normal use. For procurement, the component’s conformity to DIN norms and its HSS specification mean straightforward replacement routines and predictable stocking for maintenance teams, supporting uninterrupted production and reduced downtime.

FAQ

What is the recommended feed for centre drilling in steel?
The recommended feed for this centre drill is 0.03 mm/rev in steel up to 800 N, which balances tool life and clean chip formation.

Is the geometry suitable for lathe and turning centres?
Yes. The DIN 333 Form R geometry and 60° countersink make the TECWERK centre drill suitable for standard lathe and turning-centre applications.

Can this drill be used on hardened components?
The tool is made from HSS and is intended for general workshop use; machining of heat-treated or very hard components should be validated against the material’s properties before production use.

What benefit does the Form R radius point provide?
The radius point reduces splitting on softer materials while producing a well-defined centre recess, improving subsequent drill guidance and concentricity.

Which standards does the tool comply with?
The centring geometry follows DIN 332 Sheet 1 Form R and the designation references DIN 333 for centre drills.
