Value Collection M-23 Screw Lock Wheel Disc Mandrel

Product Description

The VALUE COLLECTION M-23 is a screw lock wheel disc mandrel designed to hold abrasive disc wheels on rotary tools and die grinders. It accepts wheels with a 3/8 inch center hole and features a 1/4 inch shank diameter for mounting in standard collets and chucks. The overall length is 2 inches, and it accommodates wheels up to 1/4 inch wide. The screw lock mechanism clamps the disc securely, reducing slippage during grinding, deburring, and surface preparation tasks. Weighing 0.1 pounds, this mandrel is a compact, lightweight accessory suited for bench and handheld rotary applications.

This mandrel is commonly used in light fabrication, metalworking, and maintenance applications where abrasive disc wheels must be mounted to a die grinder or rotary tool. It fits standard 1/4 inch collet systems found on most pneumatic and electric die grinders. Typical use cases include weld cleanup, edge deburring, and surface blending in shop or field environments. The 3/4 inch head and washer diameter provides adequate clamping surface for small-diameter abrasive wheels.

Always power down and disconnect the rotary tool or die grinder before mounting or removing the mandrel and disc. Thread the screw lock mechanism fully to ensure the abrasive disc is seated and clamped before operating. Inspect the disc and mandrel for cracks or wear before each use and follow the abrasive wheel manufacturer's maximum RPM rating.
