3M 7010299278 Disc Pad Holder M14-2.0 Internal

Product Description

The 3M 7010299278 is a disc pad holder designed for use with 4-inch diameter hook and loop abrasive discs on right angle grinders. The holder features a 1/8-inch thick foam backing layer and T-hook attachment points that work with hook and loop disc systems. The M14-2.0 internal thread mount connects directly to standard right angle grinder spindles. This type of holder is typically installed by metal fabricators, maintenance technicians, and grinding professionals who require a secure, consistent interface between the grinder and abrasive disc.

This disc pad holder is suited for surface preparation, blending, and finishing applications where hook and loop discs are the preferred consumable. It is mounted on right angle grinders and accepts 4-inch hook and loop discs. The foam backing layer helps conform to workpiece surfaces and distributes pressure evenly during grinding and finishing passes.
