3M 7010329302 Scotch-brite Ks-dc Disc 4.5 in Fine Ao

Product Description

The 3M 7010329302 is a Scotch-Brite KS-DC Clean and Finish Disc designed for surface preparation, satin finishing, blending, and polishing on a wide range of work materials. Built around a dense, thick nonwoven web construction, this disc conditions surfaces at medium pressure without damaging the base material. The aluminum oxide abrasive mineral and fine grit rating produce a tight, uniform scratch pattern suited to consistent finish work. At 4.5 inches in diameter with a 0.75-inch arbor, it mounts directly to standard angle grinders and finishing tools used in fabrication and maintenance environments.

This disc is intended for light to medium-duty surface conditioning tasks in metalworking, fabrication shops, HVAC sheet metal work, and general maintenance. It is well suited to operators who need to blend welds, prepare surfaces before coating, or achieve a satin finish on stainless steel, aluminum, or other metals. The flexible web conforms to irregular contours, making it effective on curved or profiled workpieces where rigid abrasives would leave uneven results.

Key Features

• Dense, thick nonwoven web construction performs more aggressively than softer flexible products of the same type
• Produces a tight, uniform scratch pattern for consistent satin and blended finishes
• Flexible web conforms to contours and resists loading for extended disc life
• Fine grit aluminum oxide mineral for controlled material removal without base material damage
• 4.5-inch diameter with 0.75-inch arbor fits standard angle grinders and disc finishing tools

Compatibility

Designed as an OEM-style replacement disc for standard angle grinders and right-angle finishing tools accepting a 4.5-inch diameter disc with a 0.75-inch arbor mount.

Installation Notes

Install and remove abrasive discs only after the tool is powered off and fully stopped. Verify the tool spindle speed rating meets or exceeds the disc maximum RPM before use. Wear appropriate PPE including eye protection and gloves during mounting and operation. Inspect the disc for damage before each use and discard any disc that shows tears, delamination, or deformation.
