4mm Centre Drill DIN 333 Form A 60° HSS Left-Hand Cutting, 10mm Shank, Pack of 5 - TECWERK

Take advantage of a hardened HSS construction combined with a precise 60° countersink and a 10 mm shank for stable clamping and reproducible centre holes; order the centre drill directly via Metav Werkzeuge or consult our specialists if further technical advice is required

TECWERK Centre drill DIN 333 Form A, 4 mm (HSS) – 60° countersink, left‑hand cutting

The Centre drill DIN 333 Form A, 4 mm (HSS) is a short, rigid tool for producing DIN 332 centre holes with a 60° countersink, designed for general workshop and lathe pre‑drilling applications

• High‑speed steel construction (HSS)
• 60° countersink angle for DIN 332 holes
• Left‑hand cutting for reverse operations
• 10 mm shank for secure clamping

Reliable centring for consistent drilling starts

A short, rigid centre drill delivers the exact starting point required for subsequent drilling and turning operations. Manufactured to DIN 333 Form A, this tool produces the standard 60° seat specified in DIN 332 without a protective countersink, ensuring accurate alignment of longer drills and live centres. The HSS material provides a balanced combination of toughness and wear resistance, while the recommended feed of 0.03 mm/rev in steel up to 800 N helps to avoid chatter and ensures consistent hole geometry. Accurate centring reduces rework and scrap, supporting a smoother production flow.

Solid design for secure holding and repeatability

The compact geometry and 10 mm shank provide excellent concentricity when clamped in a drill chuck or collet, minimising runout at the workpiece. With a nominal diameter of 4 mm and an overall length of 56 mm, the tool is dimensioned for stable use in both bench drills and lathes. The left‑hand cutting direction is useful for specialised operations, such as reverse machining tasks or where counter‑rotation helps during chip evacuation or tool removal. The short flute length and robust construction support repeatable centring, lowering the risk of misaligned starts and improving downstream process reliability.

Practical integration into workshop workflows

Designed for general purpose use, this centre drill suits assembly shops, toolrooms and small production lines where quick, dependable centre holes are required before drilling or turning. The tool’s compact profile shortens setup time and reduces the need for additional pilot drilling, while HSS enables economical resharpening where appropriate. For process optimisation, pair the drill with a rigid chuck and maintain the advised 0.03 mm/rev feed in medium‑strength steels; this combination promotes tool life and consistent hole quality. Documentation to recognised standards (DIN 333 / DIN 332) simplifies specification and procurement in industrial environments.

FAQ

What size and shank does this centre drill have?
The TECWERK centre drill has a nominal diameter of 4 mm with a 10 mm shank and an overall length of 56 mm (SKU 2000861574NW) suitable for standard chucks and collets.

Which standards does the tool conform to?
This centre drill is manufactured to DIN 333 Form A and is intended to produce the 60° centre seats specified in DIN 332 without a protective countersink.

What feed rate is recommended for steel?
For steels up to 800 N, the recommended feed is 0.03 mm/rev, which balances chip formation and tool life for the HSS geometry.

Is the cutting direction important for workshop use?
Yes, the left‑hand cutting orientation can be advantageous for certain reverse or specialised machining tasks; it is supplied as left‑hand cutting to match those operational needs.

Can this centre drill be used on both drills and lathes?
The tool is suitable for drill presses and lathes where a short, rigid centre drill is required to establish an accurate start for subsequent machining.
