Value Collection M-33-L Screw Lock Wheel Mandrel

Product Description

The VALUE COLLECTION M-33-L is a screw lock wheel mandrel designed to mount abrasive or polishing wheels onto rotary tools, die grinders, and similar power equipment. It accepts wheels with a 3/8-inch hole and accommodates wheel widths from 3/8 inch up to 1/2 inch. The screw lock connector secures the wheel firmly during operation, reducing the risk of slippage under load. At 2 inches overall length with a 3/8-inch shank diameter, this mandrel fits standard collets and chucks commonly found in trade and shop applications. Machinists, fabricators, and maintenance technicians are the typical users.

This mandrel suits bench-top and handheld rotary applications where small abrasive wheels must be driven at consistent speed. It is appropriate for grinding, deburring, and finishing operations on metal, composite, and similar materials. The 3/4-inch head and washer diameter provides adequate clamping surface for the supported wheel width range, keeping the wheel seated flat and stable during use.

Installation Notes

Ensure the rotary tool or die grinder is fully powered off and unplugged before mounting or removing the mandrel. Insert the 3/8-inch shank into the tool collet and tighten the collet nut securely with the appropriate wrench before attaching the wheel. Thread the screw lock fastener by hand first, then snug with a tool - do not overtighten, as this can damage the wheel or mandrel threads. Inspect the mounted wheel for cracks or damage before each use and observe applicable shop safety standards for abrasive wheel operation.
