TECWERK Centre Drill DIN 333 Form A – 3.15 mm, HSS‑Co, overlong

A TECWERK centre drill DIN 333 Form A, 3.15 mm designed for precise centre-hole preparation in metalworking, especially where extended reach and conformity to DIN 332 are required

• HSS‑Co construction for increased wear resistance
• DIN 333 Form A, 60° centre angle
• Overlong design for deep access
• 10 mm shank, right‑hand cutting

Precise centre-hole preparation for reliable machining starts

The TECWERK centre drill is engineered to ensure accurate seating for subsequent drilling and turning operations. Built to the DIN 333 specification and intended for producing centre holes as defined by DIN 332, this tool establishes the correct geometry for live- or dead-centre support. The 60° centre angle provides the standard contact form for centre support and reduces runout during subsequent operations, which helps to protect both workpiece and machine and supports consistent concentricity.

Material and geometry for extended tool life

Made from HSS‑Co (cobalt-alloy high-speed steel), the tool offers enhanced hot-hardness and abrasion resistance compared with standard HSS. The combination of the alloyed steel and the centre-drill geometry improves performance when preparing holes in general steel and other common workshop metals. The right‑hand cutting orientation and the specified feed guidance of 0.03 mm/rev (for steel up to 800 N) enable controlled chip formation and steady penetration, promoting longer tool life and predictable results.

Overlong design for deep or awkward setups

The overlength configuration gives access to deeper or recessed work zones where a standard-length centre drill would be impractical. With an overall length of 120 mm and a 10 mm shank, the tool can be used with extended toolholders or in fixtures that require additional reach, while maintaining sufficient rigidity for precise centring tasks. The design omits a protective countersink, catering to workflows that require a direct centre-drilling operation without an additional protective feature.

Practical machining data and workshop benefits

Key numeric specifications such as a 3.15 mm nominal diameter and the 60° countersink angle make tool selection straightforward for standard centre requirements. The tool’s feed recommendation and material composition translate into operational advantages: more predictable hole quality, reduced rework, and stable setup for subsequent drilling or turning. The 10 mm cylindrical shank simplifies mounting to common collets and chucks, allowing rapid tool changes in a production or jobbing environment.

FAQ

What materials is this centre drill suitable for?
The TECWERK centre drill in HSS‑Co is suited for general workshop metals; the HSS‑Co grade improves performance when machining steels and other common alloys.

How does the overlong design affect rigidity and application?
The extended 120 mm overall length provides reach into recessed areas while the 10 mm shank allows secure clamping; appropriate toolholders should be used to maintain rigidity for the intended application.

Is the tool compliant with industry standards?
Yes, the centre drill is manufactured to DIN 333 and intended to produce centre holes in accordance with DIN 332 specifications.

What feed should be used when centre drilling steel?
The specified guidance for steel up to 800 N is 0.03 mm per revolution, which helps ensure controlled cutting and consistent hole formation with this TECWERK centre drill.

Does this centre drill include a protective countersink?
No, this overlong execution is supplied without a protective countersink, for use in processes that require direct centre-hole formation.
