Take advantage of precise centring, robust HSS construction and a defined 60° centring angle to ensure repeatable centre holes in metalworking operations; order the tool directly via Metav Werkzeuge or consult our technical team for application advice.

Centre Drill DIN 333 Form A D 4 mm — HSS centre drill by TECWERK

The Centre Drill DIN 333 Form A D 4 mm is a high-precision HSS centre drill designed for producing DIN 332 centre holes in general workshop and industrial machining tasks.

• HSS construction for durability and sharpness
• Conforms to DIN 333 Form A specification
• 60° centring angle for accurate centre holes
• Right-hand cutting with 10 mm shank diameter

Reliable centring for repeatable drilling

The tool delivers consistent results by combining the standardised geometry of DIN 333 with a 60° centring angle that matches common lathe and drilling requirements. This standard conformity reduces setup variability and helps achieve correct initial guidance for subsequent drilling or turning operations. The design simplifies hole alignment and lowers scrap rates by making the initial centre mark precise and repeatable.

Robust HSS construction built for workshop environments

Manufactured from HSS, the centre drill offers a balance of toughness and hardness suitable for everyday metalworking. HSS resists heat and wear better than plain carbon steels, which prolongs tool life under frequent use. The shank 10 mm diameter ensures stable clamping in common chucks and collets, improving concentricity and minimising runout during high-speed or repetitive tasks.

Defined cutting parameters for efficient machining

The cutting geometry is right-hand cutting with a recommended feed that enables controlled material entry; in steels with up to 800 N tensile strength a typical feed of 0.03 mm/rev is appropriate. This specification supports predictable chip formation and helps prevent early blunting. Using a defined feed and the standardised tip form improves cycle time stability and reduces the need for correction passes during preparatory operations.

Easy integration into existing tool setups and workflows

The tool is intended for the production of centre holes to DIN 332 without a separate pilot countersink, allowing straightforward integration into existing machining sequences. Its standard form and dimensions make it compatible with typical tool holders and fixture arrangements found in industrial and craft workshops. The simple geometry also facilitates quick inspection and regrinding when maintenance is required, supporting uninterrupted production.

FAQ

What materials can be centred with this tool?
The TECWERK centre drill (Centre Drill DIN 333 Form A D 4 mm, SKU 2000861808NW) is made from HSS and is suitable for general metalworking; the specified feed guidance covers steels up to 800 N tensile strength.

Is the geometry compatible with standard machine setups?
Yes, the Form A geometry and 10 mm shank make the drill compatible with common chucks and collets, allowing straightforward integration into existing tool holders.

How does the 60° angle affect subsequent machining operations?
A 60° centring angle produces a standard centre that aligns with DIN 332 conventions, ensuring reliable seating for live centres and accurate starting points for drills or lathe operations.

Can the tool be reground to extend service life?
The simple centre-drill geometry allows controlled regrinding; following original tip angles preserves the intended centring performance and prolongs usable life.

What cutting direction is specified and why does it matter?
The tool is right-hand cutting, which is the standard orientation for most drilling and turning equipment; matching cutting direction reduces unexpected tool behaviour during entry.
