Merit Abrasives 08834166328 Quick-change Disc 4in Aluminum Oxide

Product Description

The MERIT ABRASIVES 08834166328 is a 4-inch non-woven aluminum oxide quick-change disc designed for surface conditioning, blending, and finishing on metal and composite substrates. Built on a flexible polyester backing with a high-loft nylon fiber construction, this disc delivers consistent medium-grade cut without loading or smearing. Clean Bond resin technology keeps the abrasive grain bonded longer, reducing debris transfer to the workpiece surface. Rated to 15,000 RPM, it is compatible with standard Type R power-lock attachment systems used on die grinders, inline grinders, and handheld disc sanders. Machinists, fabricators, and metal finishing technicians are the primary installers of this consumable.

This disc is suited for surface preparation and finishing work on 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, super alloys, titanium, and fiberglass or composite panels. Typical applications include weld blending, oxide removal, and pre-paint surface conditioning in fabrication shops, maintenance facilities, and field service environments. The flexible polyester backing conforms to slightly contoured surfaces, making it useful on tubing, fittings, and formed sheet metal components where a rigid disc would leave high spots.

Key Features

• Aluminum oxide abrasive grain with Clean Bond resin technology for smear-free finishes
• High-loft nylon fiber construction extends disc service life
• Medium grade provides moderate material removal with good surface finish
• Flexible polyester backing conforms to contoured and curved workpiece surfaces
• Type R power-lock attaching system for tool-free disc changes
• Rated to 15,000 RPM for use with die grinders, inline grinders, and handheld disc sanders

Compatibility

Designed for use with Type R power-lock quick-change tool systems on die grinders, handheld disc sanders, inline grinders, and straight grinders. Suitable for material applications including 300 Series Stainless, 400 Series Stainless, Fiberglass and Composites, Hard Carbon Steels, Soft Carbon Steels, Super Alloys, Titanium, and Tool Steels.

Installation Notes

Installation is performed by fabricators or maintenance technicians using a compatible Type R mandrel mounted in the grinder or sander. Ensure the tool RPM rating meets or exceeds the disc maximum of 15,000 RPM before mounting. Power down and disconnect the tool from its power source before changing discs. Inspect the disc for tears or abrasive separation before each use and discard any damaged disc immediately.
