1.6mm Centre Drill DIN 333 Form A 60° Left-Hand HSS, 4mm Shank - TECWERK

Benefit from the combination of HSS construction, DIN 333 Form A geometry and a 60° countersink angle for precise, repeatable centre holes. Order the centre drill directly via Metav Werkzeuge or ask our consultants if needed.

Centre drill DIN 333 Form A Ø1.6 mm HSS, left‑hand — TECWERK

The centre drill offers standardised geometry for accurate centre holes and is suited to general workshop use where a left‑hand cutting direction is required.

• HSS construction for toughness and wear resistance
• DIN 333 Form A standardised geometry
• 60° countersink angle for precise centre holes
• Left‑hand cutting, 4 mm shank for standard holders

Ensure accurate starts and concentricity with standard geometry

A correct centre hole is the foundation of subsequent machining steps. The DIN 333 Form A geometry of this centre drill provides a reliably centred pilot and a defined chamfer thanks to its 60° countersink angle, reducing runout at the outset of drilling or turning. Made from high‑speed steel, the tool combines toughness with edge retention so that starting holes remain accurate over multiple cycles. This reduces rework and contributes to predictable part quality on lathes and drill presses.

Durable cutting behaviour for repeatable production

The use of HSS material offers a balance between hardness and resistance to shock; this is particularly relevant for small diameters such as Ø1.6 mm, where brittle edges would shorten tool life. The specification includes a recommended feed in steel up to 800 N of 0.02 mm/rev, providing a practical guideline for achieving clean centre holes without overloading the tool. The left‑hand cutting direction is incorporated into the geometry to match specific machine set‑ups or applications that demand reverse rotation.

Smooth integration into workshop workflows and tool holders

With a 4 mm shank, the centre drill fits common collets and small chucks, making it easy to stock and deploy across multiple workstations. Supplied in a packaging unit of 5, the tool supports orderly inventory rotation and ensures availability for uninterrupted production. Conformity to recognised standards simplifies tool selection and interchangeability, so the centre drill functions as a dependable element in jigs or multi‑tool arrangements and reduces set‑up time during changeovers.

FAQ

What is the primary use of this centre drill?
The TECWERK centre drill DIN 333 Form A Ø1.6 mm HSS is designed to produce precise centre holes and a defined chamfer as a reliable starting point for subsequent drilling or turning operations.

Which materials is the drill suitable for?
The TECWERK centre drill is manufactured from HSS for general workshop use; the technical recommendation lists a feed of 0.02 mm/rev in steel up to 800 N as a guideline for safe, effective machining.

Why is left‑hand cutting specified for this tool?
Left‑hand cutting on the TECWERK centre drill accommodates machine set‑ups or operations requiring reverse rotation and ensures correct chip flow and engagement for those specific processes.

Will the shank fit common toolholders?
The 4 mm shank of the TECWERK centre drill is compatible with standard small collets and chucks, facilitating quick mounting and consistent concentricity in most workshop holders.

How does conformity to DIN 333 and DIN 332 help in production?
Standardisation to DIN 333 Form A and reference to DIN 332 mean the TECWERK centre drill provides predictable geometry and interchangeability, reducing set‑up variance and supporting repeatable part quality.
