3M 7100282085 Stikit Cloth Disc 180 Plus J-weight 5 Inches

Product Description

The 3M 7100282085 is a Cubitron II Stikit Cloth Disc engineered for aggressive stock removal on metal, stainless steel, and high-strength alloys. Part of the 900DZ series, it features a J-weight cloth backing and 180+ grit precision-shaped grain that fractures along sharp edges to continuously expose fresh cutting points. The open-coat construction reduces loading, and the resin bond holds grain firmly through demanding applications. At 5 inches in diameter with a Die 500X hole configuration, it mounts directly to Stikit-compatible random orbital and disc sanders. The purple backing is standard for Cubitron II identification in the shop.

This disc is suited for grinding, blending, and finishing operations in metal fabrication, weld blending, and surface preparation work. The 180+ grit rating puts it in the fine-to-ultra-fine range, making it appropriate for final-pass finishing and scratch refinement before coating or inspection. Typically installed by metal fabricators, welders, auto body technicians, and maintenance trades working on ferrous and non-ferrous substrates. Sold individually per unit; carton quantity is 50 discs, with cases containing 250 discs total.

Key Features

• Cubitron II precision-shaped grain continuously fractures to expose sharp cutting edges
• 180+ grit open-coat construction minimizes disc loading during fine finishing passes
• J-weight cloth backing provides flexibility with durability for contoured and flat surfaces
• Resin bond system maintains grain adhesion under heat and pressure
• Stikit pressure-sensitive adhesive (PSA) backing allows fast disc changes on compatible tools
• Die 500X hole configuration fits standard 5-inch Stikit disc pads

Compatibility

Designed for use with 5-inch Stikit-compatible PSA disc pads and random orbital sanders that accept the Die 500X hole configuration. Consult your tool manufacturer specifications to confirm pad compatibility before use.

Installation Notes

Installation is performed by pressing the PSA-backed disc firmly onto a clean, dry Stikit pad to ensure full adhesion contact. Power down and disconnect the sander before mounting or removing discs. Inspect the pad surface for contamination or wear that could compromise disc seating. Discs should not be forced onto incompatible pad sizes or hole patterns.
