50mm Centre Drill DIN 333 Form A 3.15mm HSS TiN Coated 60° Countersink Right-Hand - TECWERK

Take advantage of the HSS substrate combined with a TiN coating and the standardised DIN 333 Form A geometry for reliable centre-hole starts and consistent tool life; order the TECWERK centre drill directly via Metav Werkzeuge or consult our specialists for specification matching.

Centre drill DIN 333 Form A, 3.15 mm – HSS, TiN, right-hand (TECWERK)

The centre drill DIN 333 Form A, 3.15 mm, a short, rigid centre drill designed for precise centre-hole formation in general machining and workshop applications.

• HSS substrate with TiN coating
• DIN 333 Form A geometry
• 60° centring angle for accurate starts

Consistent starts that reduce run-out and rework

A reliable first operation improves the whole machining sequence. The short, rigid geometry of this centre drill ensures a precise 60° centre point that reduces lateral run-out when drilling or turning. The Form A profile to DIN 333 gives a stable cutting engagement, which is especially beneficial when facing tight tolerances on shafts or when preparing centres for subsequent drilling or turning. The predictable behaviour of the tool supports repeatable setup and quicker cycle time, translating to fewer rejected parts and smoother production flows.

Wear resistance and longer service life under load

The combination of HSS substrate and TiN coating provides balanced toughness and surface hardness: the substrate resists chipping, while the coating reduces friction and wear on the cutting edges. For series workrooms where tool changes interrupt throughput, this centre drill maintains edge life and surface finish for longer periods. The TiN layer also aids chip release and reduces built-up edge, which keeps the centring operation clean and consistent across batches.

Clear cutting data for efficient process planning

Process planners benefit from explicit empirical data: the tool is specified for a feed in steel (up to 800 N) of 0.03 mm/rev, enabling straightforward integration into existing programmes and feeds. The 3.15 mm nominal diameter and the compact overall length contribute to rigidity, while the right-hand cutting direction matches standard spindle rotations. These measurable parameters allow engineers to estimate tool life, plan reorders and set reliable process windows without prolonged trial runs.

Easy fitment and compatibility with common holders

With an 8 mm shank and 50 mm overall length, the centre drill fits typical toolholders and tailstock collets found in general workshops and small production cells. The short design minimises deflection and is therefore suitable for creating centre holes in shafts and blanks prior to drilling or turning operations. Its conformity with the DIN standard simplifies stockkeeping and ensures the dimensioning aligns with tooling charts and fixture setups.

FAQ

What materials is this centre drill suitable for?
The TECWERK centre drill (DIN 333 Form A, 3.15 mm, HSS with TiN) is primarily specified for general workshop steels; its HSS substrate and TiN coating offer good performance for low- to medium-strength steels and similar materials.

How does the TiN coating benefit the centring operation?
The TiN layer on the TECWERK centre drill reduces friction and wear at the cutting edges, improving chip evacuation and extending service life during repeated centring operations.

Which holders are compatible with the 8 mm shank?
The 8 mm shank of this centre drill fits standard collets and tailstock fittings commonly used in lathes and drill presses; the short overall length also helps to maintain rigidity in typical holders.

Can this tool be used for production centres without a protective countersink?
Yes, the geometry conforms to DIN 333 Form A and is intended for producing centre holes per DIN 332 without an additional protective countersink, streamlining initial centre preparation.

Is the provided feed recommendation applicable to CNC machines?
The specified feed of 0.03 mm/rev in steel up to 800 N is a practical guideline for both manual and CNC environments; programmers can use this value as a starting point and adjust based on machine stiffness and material batch.
