Zentrierbohrer DIN 333 Form B Ø 4 mm HSS with protective countersink — TECWERK

The Zentrierbohrer DIN 333 Form B Ø 4 mm HSS with protective countersink is a workshop-grade centre drill designed for producing accurate centring holes in turning and drilling preparations, following standardised metrology practices

• HSS centre drill, DIN 333 Form B
• Built-in protective countersink
• Right-hand cutting, 60/120° countersink angles
• For centre holes per DIN 332 sheet 1

Precise starts for turning and drilling operations

A centre drill built to DIN 333 dimensions delivers repeatable entry and alignment when preparing workpieces for turning or subsequent drilling. The HSS construction provides a balanced combination of toughness and wear resistance suitable for frequent workshop use. The integrated protective countersink prevents the small pilot from walking on entry, which reduces scrap rates and shortens setup times. By standardising the centring process, machinists achieve consistent runout control and a more predictable downstream machining performance.

Measurable efficiency and process guidance

Engineered for dependable cycle-time savings, the geometry includes a dual-angle countersink of 60/120° that produces a clean chamfer and a secure seating point. The tool is optimised for a feed of 0.03 mm/rev in steel at up to 800 N, which guides speed and feed selection to avoid premature wear. The right-hand cutting direction matches common lathe and drilling spindle orientations, simplifying tool changes and inventory. These measurable parameters support leaner process planning and fewer trial cuts on new setups.

Versatile fit for general workshop applications

With the Form B profile and compliance to centring norms such as DIN 332, the tool suits standard centring tasks across conventional and CNC machines. The geometry is intended for general-purpose workshop use, making it straightforward to stock alongside turning and drilling consumables. Where tight concentricity and accurate seating of centres are required, this centre drill integrates neatly into quality-controlled workflows and inspection routines, supporting traceable and repeatable preparation steps.

Handling, care and predictable lifetime

The HSS substrate should be used at recommended cutting speeds for long life; frequent inspection of the point prevents degraded centring quality. The protective countersink reduces burr formation and simplifies deburring needs after centring. As a single-piece supply (packaging unit: 1), the tool is ready for immediate use; the TECWERK designation denotes the specified geometry and cutting direction. For further advice on speeds, toolholders or compatible sequences, Metav's technical staff can provide concrete recommendations for the application.
