TECWERK centre drill DIN 333 Form A, HSS, Ø 0.5 mm

TECWERK centre drill for producing precise centre holes in general workshop and industrial applications, offering a compact overall length and standard 60° point for conformity with DIN specifications

• High-speed steel (HSS) construction
• DIN 333 Form A geometry
• 60° countersink angle for standard centres
• Right-hand cutting, single-ended design

Accurate starting points for reliable machining

The combination of HSS material and DIN 333 Form A geometry creates a robust tool that establishes exact starting points before main drilling. The Ø 0.5 mm nominal diameter with a 60° point generates standard centre holes that conform to accepted specifications, reducing the risk of drill walking and increasing positional repeatability. This precision is particularly valuable when subsequent operations demand tight concentricity.

Optimised feed and consistent performance in routine use

Designed for general workshop use, the tool supports a controlled feed of 0.01 mm/rev in steel at recommended cutting conditions, enabling steady chip formation and predictable behaviour. The single-ended construction and right-hand cutting orientation simplify handling and replacement in common tool holders. The compact overall length promotes accessibility in cramped set-ups while ensuring the short pilot radius gives a clear, well-defined centre for follow-up machining.

Seamless integration into production and supply chains

As part of a pragmatic tooling assortment, this compact centre drill assists in streamlining process reliability across diverse machining tasks. The precision of the ground point shortens set-up time and improves first-pass quality, which supports higher throughput and fewer reworks. Metav’s distribution and consultancy capabilities provide an additional layer of assurance for procurement and application choices, combining decades of experience with broad product availability.
