3M 7010329011 Hook Loop Disc 3 in Silicon Carbide Super Fine

Product Description

The 3M 7010329011 is a 3-inch hook-and-loop abrasive disc designed for surface finishing, blending, and light material removal on metal, wood, and composite surfaces. Built with a non-woven silicon carbide construction, this disc delivers consistent Super Fine grade cutting action across the full face of the disc. It operates at a maximum rated speed of 20,000 RPM and is flexible enough to conform to contoured work surfaces. The gray non-woven matrix resists loading and maintains cut rate across extended use. It mounts via a hook-and-loop backing for fast disc changes on compatible random orbital and angle head tools.

This disc is suited for final-stage surface prep, deburring, and finishing work in light industrial, HVAC fabrication, plumbing rough-in, and general trade shop applications. The Super Fine grade is appropriate for pre-polish blending, oxide removal on copper and stainless fittings, and surface conditioning ahead of coating or inspection. No vacuum holes are included, making it a clean fit for non-perforated backup pads. Tradespersons in sheet metal, pipefitting, and mechanical contracting will find this disc useful for finishing welds and cleaned joint areas before assembly.

Key Features

• 3-inch diameter with hook-and-loop backing for tool-free disc swaps
• Silicon carbide abrasive material for consistent cut on metal and non-ferrous surfaces
• Super Fine grade for finish blending, conditioning, and light oxide removal
• Non-woven flexible construction conforms to curved and irregular surfaces
• Rated to 20,000 RPM for use with standard random orbital and die grinder pads
• No vacuum holes — compatible with solid backup pads

Compatibility

Designed for use with 3-inch hook-and-loop backup pads on random orbital sanders, angle grinders, and die grinders that accept non-woven abrasive discs at speeds up to 20,000 RPM.

Installation Notes

Mount to a clean, dry hook-and-loop backup pad rated for the same diameter and RPM. Verify the tool and pad maximum RPM rating meets or exceeds 20,000 RPM before use. Inspect the disc for tears or separation before each use and replace if the non-woven matrix shows signs of delamination. Always wear appropriate eye and hand protection when operating abrasive discs.
