3M 7010329282 Surface Conditioning Disc 4.5 in 13000 Rpm

Product Description

The 3M 7010329282 is a non-woven surface conditioning disc built for heavy-duty deburring and finishing in industrial and fabrication environments. It uses an aluminum oxide abrasive and runs at a maximum speed of 13000 RPM. The disc measures 4.5 inches in diameter and attaches via a hook and loop system for fast changeovers during multi-step finishing operations. Its open-web fiber construction stays cool under load and resists loading, helping deliver consistent results across stainless steel, mild steel, aluminum, and other metals. Licensed HVAC, sheet metal, and fabrication technicians reach for this disc when edge work demands both aggression and control.

This disc is designed for use with compatible hook and loop backup pads on angle grinders and die grinders. It performs well on flat surfaces, contoured profiles, and irregular geometry, conforming to edges without rounding or damaging the base material. Typical applications include weld blending, edge deburring, surface prep before coating, and multi-step finishing sequences where disc changeover speed matters. It is sold individually and suited to professional shop and field use alike.

Key Features

• Non-woven aluminum oxide construction delivers aggressive cut with longer service life compared to standard SC and PD conditioning discs
• Open-web design resists loading and runs cool for consistent, repeatable surface finishes
• Hook and loop attachment enables quick disc swaps during multi-step finishing processes
• Conforms to contoured and irregular surfaces while preserving edge geometry
• Rated to 13000 RPM for compatibility with standard angle grinder speeds

Compatibility

Designed for use with hook and loop backup pads on angle grinders and die grinders accepting 4.5-inch discs. Verify backup pad rating meets or exceeds 13000 RPM before use.

Installation Notes

Installation is performed by qualified fabricators or trades personnel familiar with abrasive tool safety. Confirm the grinder and backup pad are rated for at least 13000 RPM before mounting this disc. Inspect the disc for damage before each use and never exceed the maximum rated speed. Always wear appropriate eye, face, and hand protection when operating rotary abrasive tools.
