3M 7100077042 Abrasive Disc 1.5 Inch 40 Grit 30000 Rpm

Product Description

The 3M 7100077042 is a Cubitron II Roloc durable edge disc designed for fast, consistent material removal on metal and similar surfaces. Built around 3M Precision-Shaped Grain technology, the disc delivers sharp, cool cutting action that stays consistent throughout the disc's life. The poly-cotton backing is rated to an X-weight class, giving it the tensile strength needed to hold up against edge work without fraying or tattering. At 1.5 inches in diameter and rated for up to 30000 RPM, it is sized for die grinders and right-angle tools equipped with a Roloc-style quick-change spindle. Installers and fabricators working on tight contours or part edges will find the combination of sharp grain and durable backing well-suited to the task.

This disc is intended for edge grinding, deburring, and surface conditioning applications where a compact disc format is required. The Roloc quick-change attachment system allows the disc to be swapped without tools, reducing downtime during multi-step grinding or blending operations. The evenly spaced grain layout includes gaps that help debris escape the cutting surface, reducing loading and extending usable life. This makes the disc a practical choice for professional metal fabricators, welders, and maintenance technicians working in production or field environments.

Key Features

• 3M Precision-Shaped Grain provides sharp, cool, and consistent cutting action across the disc's lifespan
• Evenly spaced grain with debris-escape gaps resists loading and extends abrasive life
• Heavy X-weight poly-cotton backing resists fraying and tattering, built specifically for edge work
• Roloc quick-change attachment allows fast disc-to-tool mounting without additional hardware
• 1.5 inch diameter and 30000 RPM rating suited for compact die grinders and angle tools

Compatibility

Designed for use with Roloc-compatible quick-change tool spindles on die grinders and right-angle grinders accepting 1.5 inch disc formats.

Installation Notes

Installation and disc changes should be performed by qualified metalworking or maintenance professionals. Before mounting or removing the disc, ensure the tool is powered off and disconnected from its power source. Verify that the tool's rated RPM meets or exceeds the disc's 30000 RPM rating before use. Inspect the disc for damage before each use and discard any disc that shows signs of cracking, delamination, or heavy wear.
