3M 7100332405 Quick-change Disc 3 in 80 Grit Ceramic 50 Pack

Product Description

The 3M 7100332405 is a TSM quick-change abrasive disc from the Cubitron 3 series 1184F, designed for precision grinding and finishing on stainless steel, nickel alloys, cobalt, Inconel, titanium, and chrome. The disc features a closed-coat ceramic abrasive on a YF-weight polyester cloth backing. Ceramic grain self-sharpens during use, sustaining cut rate longer than conventional abrasives. An additional coating on the disc face minimizes heat buildup at the workpiece surface, making this disc well-suited for heat-sensitive metals where thermal damage is a concern. Sold in a 50-disc pack, the 7100332405 is a production-grade solution for metal fabrication and weld-blending applications.

This disc is intended for use with TSM quick-change disc holders on angle grinders and straight-line sanders. At 3 inches in diameter with an 80 grit rating (medium grade), it fits standard production workflows for weld removal, surface conditioning, and stock removal on exotic and heat-sensitive alloys. The flexible cloth backing conforms to curved and contoured surfaces, making it effective on formed parts as well as flat stock. Typical users include sheet metal fabricators, aerospace maintenance technicians, and welding professionals working with specialty metals.

Key Features

• Ceramic abrasive grain self-sharpens continuously for sustained cut rate and cooler surface temperatures
• Additional surface coating reduces heat transfer into heat-sensitive alloys during grinding
• Closed-coat coverage delivers faster material removal and a smoother finish compared to open-coat alternatives
• YF-weight polyester cloth backing provides flexibility for contoured surfaces and resists tearing under load
• TSM quick-change attachment system for rapid disc changes without tools
• Rated for up to 20,000 RPM for use with standard angle grinders

Compatibility

Designed for use with TSM quick-change disc holders. Suitable for grinding and finishing stainless steel, nickel alloys, cobalt, Inconel, titanium, and chrome workpieces.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or locked out per applicable safety procedures. Verify that the tool spindle speed does not exceed the disc maximum operating speed of 20,000 RPM before operation. Inspect the disc for damage before each use and discard any disc that appears torn, delaminated, or deformed. Use of the correct TSM backing pad is required to ensure secure disc retention during operation.
