The body-only version of our Stronghold Oneway scroll chuck kit (without jaws, woodworm screw or taper-lock adapter). Uses a 5:1 ratio chuck key for tightening, ensuring greater holding power on large pieces. The nickel-plated body weighs 8 lb, and has case-hardened base jaws and a scroll coated with a dry, long-lasting lubricant. Precisely made, the chuck body typically has less than 0.001" of runout; with the jaws mounted, runout can be expected to be less than 0.005".
Made in Canada.
