3M 7000045177 Abrasive Disc 80 Grit 1.5 in Cubitron Ii 984F

Product Description

The 3M 7000045177 is a coated abrasive disc engineered for medium to high pressure grinding on metal workpieces where a compact disc size is required. Built on the Cubitron II 984F platform, it uses 3M Precision-Shaped Grain (PSG) technology — triangular ceramic abrasive grain that fractures to maintain sharp cutting points throughout the disc life. The Roloc quick-change attachment system allows fast disc swaps without tools. At 1.5 inches in diameter and 80 grit, this disc is sized for precision edge work and tight-access grinding where a standard larger disc cannot reach.

This disc is designed for demanding metalworking applications including stainless steel, cobalt chrome, and nickel alloy grinding. The 2-ply backing provides structural rigidity for edge grinding at elevated pressure. A grinding aid is incorporated directly into the disc construction to reduce heat buildup — a critical factor when working on heat-sensitive alloys such as stainless steel and nickel-based materials. Typical users include fabricators, aerospace technicians, and metalworking professionals performing weld blending, edge deburring, and surface preparation on precision components.

Key Features

• Precision-Shaped Grain (PSG) maintains sharp cutting geometry throughout disc life, reducing pressure required per pass
• Grinding aid built into the disc minimizes heat generation on stainless steel and heat-sensitive alloys
• Roloc quick-change attachment system enables fast disc swaps between grits or applications
• 2-ply backing construction supports medium to high pressure grinding and edge work durability
• Compact 1.5-inch diameter suits tight-access areas and precision edge grinding tasks

Compatibility

Designed for use with Roloc-compatible right-angle grinders and die grinders that accept 1.5-inch quick-change discs. Suited for stainless steel, cobalt chrome, and nickel alloy workpieces in medium to high pressure grinding applications.

Installation Notes

Installation of Roloc discs requires a compatible Roloc mandrel or holder mounted to a right-angle grinder or die grinder — confirm mandrel size matches the disc before use. Ensure the grinder is powered off and disconnected from the power source before attaching or removing discs. Wear appropriate PPE including face shield and gloves when grinding metal. Follow the tool manufacturer maximum RPM rating and do not exceed it with this disc.
