Merit Abrasives 08834174102 Disc Backing Pad Psa 6000 Rpm

Product Description

The MERIT ABRASIVES 08834174102 is an adhesive PSA disc backing pad designed to hold pressure-sensitive adhesive abrasive discs securely during grinding and finishing operations. It accepts a 0.25 inch shank for chuck or collet mounting and is rated for a maximum speed of 6,000 RPM. This backing pad is a consumable tooling component used in surface preparation, stock removal, and finishing workflows across metalworking, woodworking, and general fabrication environments. Licensed trades and shop technicians rely on this type of pad to maintain consistent disc contact and extend abrasive life on rotary tools, die grinders, and right-angle grinders.

This backing pad suits shop and field applications where PSA-backed abrasive discs are the preferred consumable format. The 0.25 inch shank makes it compatible with standard die grinders and similar rotary tools commonly used in metal fabrication, automotive bodywork, and general surface finishing. It is intended for single-operator, hand-held tool use rather than stationary machine mounting. Package quantity is one pad per unit.

Key Features

• Adhesive PSA backing interface holds pressure-sensitive abrasive discs without mechanical fasteners
• 0.25 inch shank fits standard die grinder and rotary tool collets
• 6,000 RPM maximum rated speed for safe operation within tool speed limits
• Lightweight at 0.5 pounds for reduced operator fatigue during extended use
• Sold individually, allowing single-unit replacement as needed

Compatibility

Designed as a standard replacement backing pad for use with PSA-backed abrasive discs on die grinders and rotary tools equipped with a 0.25 inch collet or chuck.

Installation Notes

Installation is performed by trade machinists, fabricators, or technicians using rotary or pneumatic die grinders. Power down and disconnect the tool from its air or electrical supply before mounting or removing the backing pad. Thread the shank fully into the collet and tighten securely before attaching any abrasive disc. Never exceed the 6,000 RPM maximum rated speed, and always verify the abrasive disc speed rating meets or exceeds the tool speed before use.
