Drill chuck SK-511 (APU) — self‑tightening, SK40, DIN 69871A (Vertex)
A self‑tightening drill chuck, Drill chuck SK-511 (APU), engineered for SK40 taper spindles and intended for precision clamping of small-diameter tools across general workshop and production applications
- Self‑tightening APU design for secure clamping
- Compatible with SK40-APU08 collets
- Collet range Ø0.5–8 mm
- DIN 69871A taper for standard spindles
Secure clamping for repeatable machining results
The self‑tightening mechanism delivers consistent clamping force that simplifies tool changes while maintaining concentricity. Designed to work with SK40 collet systems, the chuck supports a collet range Ø0.5–8 mm, enabling precise mounting of drills and small cutters. This reliability reduces the need for repeat operations and contributes to stable process quality in batch and single-piece production. The chuck’s balanced design supports steady rotation, improving surface finish and extending tool life.
Standardised mounting for easy integration
Compliance with DIN 69871A ensures the chuck mates with common machining centres and toolholders, allowing straightforward retrofit and interchangeability. The combination of the standard taper and the SK40-APU08 collet interface simplifies machine setup and inventory management. For production planners and toolroom managers, this means fewer bespoke adapters and a predictable equipment footprint, which supports streamlined maintenance schedules and faster changeovers.
Practical workshop benefits and handling
Weighing approximately 1.4 kg, the unit is robust without being cumbersome, which helps during manual handling and fixture changes. The compact diameter (35.6 mm) and the proven Vertex workmanship make the chuck suitable for tight spindle noses and constrained tool magazines. The design emphasises both ergonomic handling and compatibility with existing collet inventories, so integration into daily workflows is efficient and low-friction.
Built for precision, specified for professionals
As a plain but essential toolholder, the chuck prioritises measurable performance: repeatable concentricity, secure clamping and standardised mounting. Those responsible for quality assurance will value the clear specification and the ability to verify performance with routine checks. Where process reliability matters, choosing a standardised, self‑tightening chuck reduces variability and supports consistent production output without requiring complex user adjustments.
