Value Collection M-21 Sanding Disc Adapter 2 in

Product Description

The VALUE COLLECTION M-21 is a sanding disc adapter designed to mount abrasive discs onto rotary tools and handheld grinders. At 2 inches in length with a maximum disc hardware diameter of 1/4 inch, this adapter provides a secure interface between the tool spindle and the sanding disc. It fits tools with a 1/8 inch hole size and accommodates discs up to 1/4 inch maximum wheel width. Weighing 0.2 pounds, the M-21 is a compact, lightweight component suited for both bench-mounted and portable rotary applications. Machinists, fabricators, and maintenance technicians commonly use this type of adapter when changing disc configurations on standard rotary equipment.

This adapter is appropriate for use in light industrial, fabrication, and maintenance environments where sanding discs must be mounted to rotary tools with 1/8 inch spindle hole sizing. It is well suited for detail sanding, surface preparation, and finishing work on small workpieces. The compact 2 inch length keeps the adapter close to the tool body, reducing runout and improving disc stability during operation. It is typically installed by machinists, tool room technicians, or maintenance professionals working with bench grinders or die grinders.
