TECWERK centre drill DIN 333 Form R — 4 mm, HSS, right-hand

The TECWERK centre drill DIN 333 Form R 4 mm HSS is a right-hand cutting centre drill designed for reproducible centring to DIN 332 Sheet 1 Form R with a 60° countersink angle for subsequent turning or drilling operations

• HSS for high wear resistance
• DIN 333 Form R centring profile
• 60° countersink angle for standard centres
• Right‑hand cutting with predictable chip control

Consistent centre geometry for accurate downstream machining

The tool is engineered to produce precise centre holes to DIN standards, ensuring correct seating for live centres and reliable alignment before turning or drilling. Made from HSS, the drill keeps its cutting edge under typical workshop loads and thus reduces rework caused by misaligned workpieces. The Form R profile — a centred point with a radius rather than a sharp cone — provides a stable reference that lowers runout during subsequent operations and simplifies chucking and tailstock positioning.

Predictable cutting behaviour and measurable machining parameters

The right‑hand cutting design delivers steady chip flow and controlled entry into the material; this behaviour is backed by the specified countersink angle of 60° and the recommended feed in steel of 0.03 mm/rev at up to 800 N. Explaining the parameter: feed per revolution refers to the axial advance for each spindle turn and is a key setting on lathes and drill presses for repeatable results. The standardised geometry and material choice mean the tool performs consistently across common workshop setups and machining centres, providing measurable productivity improvements.

Practical workshop benefits and supply reliability

The compact design is intended for general use in metalworking shops where standardised centring is required before finishing operations. The combination of a DIN‑compliant form and HSS material means low maintenance and straightforward sharpening where applicable. As part of an industrial supply chain, sourcing through Metav brings added assurance: central stock management in Emmerich supports reliable deliveries and access to technical advice, reducing procurement complexity for small and large workshops alike.

FAQ

What is the intended application of this centre drill?
The TECWERK centre drill DIN 333 Form R 4 mm HSS is intended for creating accurate centre holes to DIN 332 Sheet 1 Form R as a preparatory operation for turning and drilling.

Which materials is the centre drill suitable for?
The drill is specified for general use in metalworking; the HSS construction suits common steels and workshop materials where standard centring is required.

How should the feed be set when centring steel?
Follow the recommended feed of 0.03 mm per revolution in steel at cutting conditions up to 800 N to achieve consistent penetration and chip formation.

Does the Form R profile differ from a standard sharp centre?
Yes; the Form R profile includes a radius at the centre point, offering a more stable seating for live centres and reducing runout during subsequent operations.

Is this centre drill right‑hand or left‑hand cutting?
The tool is a right‑hand cutting centre drill, designed for conventional spindle rotation and predictable chip evacuation.
