TECWERK centre drill DIN 333 Form A — 3.15 mm HSS, 60° countersink

A TECWERK centre drill DIN 333 Form A designed for producing standard-compliant centre holes and pilot countersinks in general workshop and production environments

• HSS high-speed steel construction
• DIN 333 Form A standard
• 60° countersink angle for precise centres
• Feed 0.03 mm/rev in steel up to 800 N

Precise centring to reduce rework and improve tool life

The centre drill is purpose-built to create accurate starting points for subsequent drilling and turning operations, ensuring concentricity and minimising runout. With a 3.15 mm nominal diameter and a 60° countersink geometry, the tool produces reliably shaped centre holes that match industry practice. The compliance with DIN 333 and the ability to provide centring according to DIN 332 without an additional protective countersink streamlines setup and reduces operator interventions, resulting in fewer scrapped parts and more consistent downstream tolerances.

Durable high-speed steel and stable cutting parameters

Manufactured from HSS, the tool combines toughness with wear resistance for general workshop use. The specified feed capability of 0.03 mm/rev in steels up to 800 N indicates a balanced cutting regime that supports controlled chip formation and predictable tool life in common steel grades. Explaining the number: a feed of 0.03 mm per revolution means a cautious, repeatable advance suitable for centre-drilling tasks, which helps protect both the workpiece and subsequent twist drills. This technical stability translates into fewer interruptions and more efficient batch processing.

Simple integration into production workflows

As a standardised Form A centre drill, the item fits established tooling systems and can be adopted easily across machines and shift teams. The clear specification to DIN 333 simplifies procurement and inventory management, reducing the need for bespoke adjustments. Because the tool focuses on reliable start holes rather than decorative finishing, it shortens cycle time for centre preparation and improves first-pass quality, contributing to smoother process capability and predictable throughput for both small workshops and larger production cells.

FAQ

What material is the tool made of?
The TECWERK centre drill is made of HSS (high-speed steel), chosen for its combination of toughness and wear resistance suitable for general centring tasks.

Which standards does this centre drill comply with?
The tool is specified to DIN 333 Form A and is intended to produce centre holes in accordance with DIN 332 without a protective countersink where that practice is acceptable.

What cutting parameters are recommended?
A feed of 0.03 mm/rev in steels up to 800 N is given as a reliable parameter for controlled cutting and repeatable results with this centre drill.

Is the diameter compatible with standard toolholders?
The 3.15 mm nominal diameter and Form A geometry follow common centre-drilling conventions, enabling straightforward use in standard holders and chucks.

Can this centre drill be used for all steels?
The tool is suitable for general steel grades within the stated feed and strength range; for hardened or exotic materials, consult application data to confirm suitability for specific alloys.
