INT-8-JC20 Drill Chuck by Vertex — 36 mm, integrated self‑tightening

The INT-8-JC20 drill chuck is an integrated, self‑tightening chuck designed for precision clamping in small to medium workshops, compatible with spindles featuring a JC-20 taper.

• Integrated self-tightening mechanism
• Clamping range 0.5–8 mm
• JC-20 taper for standard spindles
• Compact 36 mm body, 0.8 kg weight

Reliable clamping for consistent drilling results

A self‑tightening clamping system delivers repeatable torque transfer and reduces slippage when using twist drills and small end mills. The self‑tightening action improves concentricity under load, which leads to fewer rejected parts and less rework in production. Where repeatability matters, this compact clamping device ensures stable tool retention across a broad 0.5–8 mm range, supporting accurate holemaking without constant retightening.

Straightforward integration with standard spindles

The chuck mounts on a JC-20 taper, a common interface for light industrial spindles, enabling fast installation on compatible machines. With a compact diameter of 36 mm and a modest mass of 0.8 kg, the unit is suited to bench drills and smaller machining centres where space and spindle balance are critical. The taper interface simplifies retrofits and reduces setup time, thereby improving machine utilisation and workflow efficiency.

Minimal upkeep and practical workshop benefits

Designed for durable service life, the clamping mechanism requires only routine cleaning and lubrication; downtime for maintenance is therefore limited. The robust design of the jaw system and the integrated concept reduce the number of separate parts to handle, streamlining tool changes and inventory. For workshops aiming to increase throughput while maintaining precision, this clamping solution combines practical maintenance demands with reliable performance.
