3M 7100074886 Cubitron Ii Hookit Disc 5 Inch 180 Grit

Product Description

The 3M 7100074886 is a coated abrasive disc built around 3M Precision Shaped Grain technology. The triangular ceramic mineral is engineered to slice through material rather than plow across the surface the way conventional abrasives do. The result is faster stock removal with a longer service life. At 5 inches in diameter and 180 grit, this disc suits finishing and blending work where controlled cut rate and surface quality both matter. Hook and loop backing allows quick disc changes without tools, keeping downtime low during production runs. This disc is sold individually and is intended for use by metalworkers, fabricators, and trade professionals running orbital or random-orbit sanders.

This disc is suited for stock removal and surface finishing across a wide range of substrates including steel, stainless steel, aluminum, and composites. The 180 grit rating makes it appropriate for finishing passes, blending welds, and light material removal where a finer surface profile is needed. The hook and loop attachment system is compatible with standard 5 inch Hookit backup pads. It is well suited to both production fabrication environments and fieldwork where disc change speed and consistent cut performance are priorities.

Key Features

• 3M Precision Shaped Grain ceramic mineral slices material rather than gouging, delivering up to 2x faster cut than conventional abrasives
• Service life rated up to 4x longer than conventional abrasive discs
• 5 inch diameter with 180 grit for finishing, blending, and controlled stock removal
• Hook and loop backing for tool-free disc changes on compatible backup pads
• Suitable for a wide range of substrates with a focus on stock removal applications

Compatibility

Designed for use with 5 inch hook and loop backup pads on orbital and random-orbit sanders compatible with Hookit attachment systems.

Installation Notes

Mount to a 5 inch hook and loop backup pad before powering on the sander. Confirm the backup pad surface is clean and free of debris to ensure full disc adhesion. Inspect the disc for damage before each use and replace if the abrasive layer shows uneven wear or delamination. Always wear appropriate eye and respiratory protection when grinding or sanding metal and composite substrates.
