Product range

Six families, one tolerance standard

Every chuck is machined, heat-treated and ground in-house, then 100% checked for run-out, clamping force and jaw play before packing.

Why buyers switch to us

Consistency is the product.

A chuck that runs true on sample one and wobbles on sample 5,000 destroys your brand. So we control the whole chain — from bar stock and heat treatment to grinding, assembly and 100% final inspection.

  • In-house CNC turning, heat treatment and taper grinding
  • 100% run-out check with 0.001 mm dial gauges — every single piece
  • Jaw hardness 58–62 HRC, salt-spray tested housings
  • OEM branding: laser mark, colour sleeve, retail blister or bulk carton
  • PPAP-style sample report and 12-month warranty on every order
