Arc Abrasives 31470 Surface Conditioning Disc 3 in 180 Grit

Product Description

The ARC ABRASIVES 31470 is a 3-inch surface conditioning disc designed for material preparation, blending, and finishing tasks in metalworking and fabrication environments. Built on an aluminum oxide resin fiber substrate, this Type S quick-change disc mounts directly to compatible quick-change mandrels without additional hardware. At 180 grit, it delivers fine surface conditioning suited for light deburring, scratch removal, and pre-finishing work on metal, stainless steel, and similar substrates. Weighing 0.176 pounds per disc, it is a lightweight consumable sold in quantities appropriate for ongoing shop use. Fabricators, pipefitters, and maintenance mechanics rely on this disc format for consistent, repeatable surface prep.

This disc is suited for use in general metal fabrication shops, HVAC duct work, pipe fitting, and mechanical maintenance applications. The Type S quick-change attachment style is compatible with angle grinders and die grinders fitted with a Type S mandrel. The 180-grit rating makes it appropriate for final blending passes and light surface conditioning rather than aggressive stock removal. It performs on ferrous metals, stainless steel, and aluminum in both bench and on-site service scenarios.

Key Features

• 180 grit aluminum oxide construction for fine surface conditioning and blending
• Type S quick-change mount for fast disc swaps without tools
• 3-inch diameter fits standard quick-change mandrels on angle and die grinders
• Resin fiber backing provides durability through repeated passes
• Lightweight at 0.176 pounds per disc, minimizing tool fatigue during extended use

Compatibility

Designed for use with Type S quick-change mandrels on angle grinders and die grinders rated for 3-inch abrasive discs.

Installation Notes

Mounting and removal of quick-change discs should be performed with the grinder powered off and unplugged or with the air supply disconnected for pneumatic tools. Verify the mandrel type matches the Type S attachment before use. Inspect the disc for cracks or damage before each use and replace immediately if any defect is found. Follow applicable ANSI B11 and OSHA 1910.215 guidelines for abrasive wheel use and guarding.
