TECWERK centre drill DIN 333 Form A, Ø6.3 mm (HSS, 60° point)

The TECWERK centre drill DIN 333 Form A is a workshop-grade tool for producing standard centre holes and ensuring accurate workpiece alignment in general machining tasks.

• HSS construction for long service life
• 60° point for standard centre holes
• DIN 333 Form A geometry for consistent centring

Repeatable centring thanks to robust geometry and material

The TECWERK centre drill combines HSS material with a disciplined geometry to produce consistent centre bores. The 60° point angle conforms to standard centring practice and supports accurate locating for subsequent operations. With a nominal diameter of 6.3 mm and a 16 mm shank, the tool is designed for secure clamping in standard drill chucks or holders, reducing runout and improving repeatability. The DIN 333 Form A specification indicates a standardised profile intended for general-purpose centre drilling, providing a familiar baseline for workshop set-ups.

Simple integration into workshop workflows for reliable results

Formulated for routine and demanding tasks alike, the centre drill offers a direct benefit in setup speed and process stability. The tool’s Form A geometry enables the creation of centre holes that meet DIN 332 requirements without the need for a protective countersink, simplifying the sequence of operations. For machinists this translates into fewer tool changes and a lower risk of misalignment during transfer from centre-drilling to turning or drilling, which helps to keep cycle times consistent and predictable.

Practical machining guidance to optimise life and finish

Operationally, the drill performs well in steel under the recommended feed; a guideline of 0.05 mm/rev in steels up to 800 N provides an efficient balance between material removal and tool life. The right‑hand cutting orientation is suitable for standard spindle rotation. The overall length of 71 mm offers sufficient reach for most centre-drilling tasks while maintaining rigidity. These measurable parameters make it straightforward to set up feeds and speeds on manual and CNC machines, ensuring precision and a clean entry point for subsequent tooling.

Dependable choice for workshops and production environments

As a compact, purpose-built tool, this centre drill supports quality-conscious workshops that prioritise repeatability and secure clamping. The use of proven high-speed steel contributes to wear resistance and predictable regrinding intervals where applicable, while the standardised geometry eases integration into existing fixtures and procedures. For facilities seeking a balance of reliability and familiar standards compliance, this tool is a pragmatic addition to the tooling inventory.

FAQ

What materials is this centre drill intended for?
The TECWERK centre drill is manufactured from HSS and is suitable for producing centre holes in typical workshop steels; the specified guideline feed for steel up to 800 N is 0.05 mm/rev.

Can the tool be clamped in standard chucks and holders?
Yes. The 16 mm shank diameter allows secure clamping in common drill chucks and dedicated centre drill holders to reduce runout during drilling.

Does the geometry comply with recognised standards?
The tool follows DIN 333 Form A geometry and is intended to produce centre holes compatible with DIN 332 without a protective countersink.

What is the point angle and why does it matter?
The centre drill has a 60° point angle; this angle yields a standardised centre bore that facilitates accurate workholding and subsequent operations such as turning or drilling.

Is there a recommended feed rate for reliable operation?
For steels up to 800 N, a feed of 0.05 mm/rev is a practical starting point that balances surface finish and tool life.
