VEVOR KP96 3.75" Self-Centering Lathe Chuck

The VEVOR KP96 is a 3.75 inch four-jaw self-centering lathe chuck designed for precision machining on lathes, grinders and milling machines. It is built from hardened #45 steel with a chrome-plated finish for hardness and rust resistance. The chuck suits machinists who need accurate, repeatable clamping of round or irregular workpieces in a workshop environment.

Clamping limits define the work envelope

Inner clamping range spans 1.26 to 2.75 inches while outer support range covers 1.77 to 3.4 inches. The M33 × 3.5 TPI internal thread mounts directly to compatible spindles. Runout is specified at 0.15 mm on the outer diameter and 0.40 mm radial runout at 50 mm test bar distance. Buyers needing larger diameters or different thread patterns cannot use this chuck.

0.3 mm bearing tolerance governs precision

The bearing tolerance of 0.3 mm (0.01 inch) is the single figure that determines whether this chuck meets a shop's accuracy requirements. It dictates the achievable concentricity for turning, grinding and milling operations. If tighter tolerance is required, this model will not satisfy the application.

Questions about this item

Should I choose the 3.75 inch KP96 or a different diameter for my lathe?

The KP96 has a 3.75 inch outer diameter with an M33 x 3.5 TPI internal thread; match this thread to your spindle or use the included 1 x 8 TPI adapter for compatibility.

What does the 0.15 mm outer diameter runout mean for my turning accuracy?

A 0.15 mm runout on the 96 mm body keeps workpieces centred within that tolerance, suitable for general precision machining and grinding tasks.

Does the M33 x 3.5 TPI thread limit which lathes I can mount this chuck on?

The chuck fits spindles with an M33 x 3.5 TPI thread directly; the supplied 1 x 8 TPI adapter extends fitment to lathes using that common thread standard.
