✅ High Concentricity 3-Jaw Chuck: Synchronized three-claw self-centering, high bite tightness, effectively avoid bit wobble & slipping for smooth precise drilling.

✅ Multiple Styles & Thread Options: Hand-tight / Ratchet lock, full black/red-black color options; 3/8/1/2 standard UNF thread + M10×1.5 for angle grinder conversion, two clamping sizes cover common drill bits.

✅ Anti-Jam Upgraded Version: Optimized internal structure to prevent jaw stuck from metal dust, longer service life for frequent industrial use.

Thread Selection Guide

Common internal thread options: 3/8"-24UNF & 1/2"-20UNF

Spindle diameter ≈9.5mm → choose 3/8"-24UNF thread chuck
Spindle diameter ≈12.7mm → choose 1/2"-20UNF thread chuck

Cordless drill with spindle lock: compatible with both single-shell & double-shell keyless chucks
Cordless drill without spindle lock: only fit double-shell keyless chucks
