TECWERK Centre drill DIN 333 Form A — 4 mm, HSS with TiN coating

The TECWERK centre drill DIN 333 Form A is a short-centre drill designed for accurate centring and the production of pilot holes in metalworking, optimised for general workshop and industrial use.

• TiN coating for longer tool life
• Conforms to DIN 333 Form A geometry
• 60° tip angle for accurate centring
• 10 mm shank for secure clamping

Accurate centring for reliable hole starts

The short, rigid geometry provides stable penetration and repeatable alignment when preparing workpieces for drilling or turning operations. The 4 mm nominal diameter and 60° tip angle match the requirements for standard centring tasks, reducing run-out and improving subsequent tool alignment. The combination of HSS base material with a TiN coating increases wear resistance during repetitive cycles, which keeps setup time to a minimum and maintains machining accuracy over longer production runs.

Consistent performance under material stress

The tool is engineered for efficient cutting in common shop steels; with a recommended feed of 0.03 mm/rev in steels up to the specified cutting resistance, the drill balances cutting force and surface finish while limiting chipping. The right-hand cutting geometry and robust shank design (Ø 10 mm) ensure stable torque transmission in standard chucks and quick-change systems. This stability benefits cycle time and reduces scrap rates in batch work and single-piece flow alike.

Durable design for everyday workshop demands

Manufactured to the DIN 333 standard as Form A, the drill provides a known, interchangeable geometry for workshops that rely on consistent tooling. The TiN coating not only extends tool life but also supports cleaner chip evacuation and reduced friction at the cutting edge, which results in fewer heat-related tool failures. With an overall length of 56 mm, the tool suits close-quarter set-ups while still providing sufficient working reach for typical centring applications.

FAQ

What is the nominal diameter and shank size of the centre drill?
The centre drill has a nominal diameter of 4 mm and a shank diameter of 10 mm, matching standard chuck and collet sizes for secure clamping.

Is the drill suitable for hardened materials?
This TECWERK centre drill is made of HSS with a TiN coating; it is intended for general steel applications. For hardened or specialty alloys, consider tools specifically rated for those materials.

What standard does the geometry follow and why does that matter?
The geometry follows DIN 333 Form A, ensuring compatibility with standard centring requirements and predictable centring angles for subsequent drilling or turning operations.

How does the TiN coating benefit workshop use?
The TiN coating increases surface hardness, reduces friction, and improves wear resistance, which leads to longer tool life and more consistent centring performance in repetitive tasks.

What feed should be used for centring in standard steels?
A recommended feed of 0.03 mm/rev in steels up to the indicated resistance provides a balance between cutting efficiency and edge life.
