INT-16-JC20 Drill Chuck – Integrated self‑tightening clamping head with JC‑20 taper by Vertex

A INT-16-JC20 Drill Chuck engineered for secure toolholding in workshop and industrial spindles, combining a compact 57 mm profile with an integrated self‑tightening mechanism for dependable machining.

• Integrated self‑tightening clamping mechanism
• Jacobs taper JC‑20 mounting
• 57 mm outer diameter for compact setups
• Robust construction, weight 1.8 kg

Greater process reliability through self‑tightening clamping

The integrated self‑tightening mechanism converts spindle rotation into a firmer bite as torque increases, reducing the risk of tool slip during heavy cuts. This built‑in behaviour delivers a measurable improvement in clamping reliability compared with standard chucks, supporting consistent machining results and fewer interrupted cycles. The design reduces setup time and helps maintain concentricity under load, which is particularly relevant when repeatability is critical in production workflows.

Compact design that fits tight installations

With a 57 mm outer diameter and modest mass (1.8 kg), the clamping head suits confined assemblies and retrofits where space is limited. The compact envelope minimises overhang and can reduce dynamic imbalance in smaller spindles, improving surface finish and prolonging bearing life. For workshops adapting older machines or integrating new toolholders, the reduced footprint enables closer tool spacing and more flexible fixture arrangements without sacrificing stiffness.

Compatibility and mounting with JC‑20 Jacobs taper

Fitted for a JC‑20 Jacobs taper, the chuck offers straightforward mounting to spindles using established taper standards. The Jacobs taper provides a precise, repeatable interface that is commonly available on a wide range of drill heads and machine tools, easing integration. Where required, the taper connection can be used with standard retention methods; this ensures the clamping head remains correctly seated under machining forces, supporting long‑term dimensional stability.

Practical maintenance and workshop benefits

The straightforward mechanical principle of the self‑tightening mechanism reduces maintenance complexity: periodic inspection and lubrication are typically sufficient to retain performance, and the robust construction prioritises uptime. The compact clamping solution is suitable for general drilling and light‑to‑medium machining tasks where secure tool retention and compactness deliver tangible workflow benefits. For teams focusing on efficient machine utilisation, this solution supports predictable production cycles and rapid changeovers.

FAQ

What mounting interface does this chuck use?
The INT-16-JC20 drill chuck is mounted via a JC‑20 Jacobs taper, a common, precision taper for secure spindle interfaces.

Is the clamping action suited to high‑torque drilling?
Yes, the integrated self‑tightening mechanism increases clamping force with spindle torque, improving tool retention under demanding loads.

What are the outer dimensions and weight?
The clamping head has an outer diameter of 57 mm and weighs 1.8 kg, making it suitable for compact installations.

Can the chuck be used on older drill spindles?
Compatibility depends on the spindle taper; where a JC‑20 seat is present or can be adapted, the chuck by Vertex fits reliably.

How should the chuck be maintained?
Regular inspection, occasional lubrication of moving parts and checking taper seating are recommended to preserve performance and longevity of the INT-16-JC20 drill chuck.
