3M 7100145447 Abrasive Film Disc 240 Grit 5 Inch Ceramic

Product Description

The 3M 7100145447 is a coated abrasive film disc engineered for high-speed stock removal across a wide range of substrates. Built on a durable film backing that resists tearing and retains edge integrity, this disc uses 3M Precision Shaped Grain technology — a triangular ceramic mineral designed to slice through material rather than plow or gouge like conventional abrasive grain. The result is a disc rated to cut up to 2 times faster and last up to 6 times longer than standard abrasives. At 240 grit and 5 inches in diameter, it is suited for finish-stage stock removal where consistent scratch patterns matter.

This disc is designed for use in surface preparation and finishing applications where controlled material removal is the primary objective. The Stikita attachment system allows fast, tool-free disc changes, reducing downtime on the floor. It performs across metal, composites, and other common industrial substrates. The 240 grit designation makes it appropriate for intermediate to fine stock removal passes in fabrication, weld blending, and general surface conditioning work.

Key Features

• Precision Shaped Ceramic Grain slices substrate rather than gouging, extending disc life up to 6 times versus conventional abrasives
• Cuts up to 2 times faster than conventional abrasive discs
• Film backing provides greater tear resistance and consistent edge retention during use
• Stikita attachment system enables fast, easy disc swaps without tools
• 240 grit rating suited for controlled stock removal and surface conditioning
• 5 inch diameter fits standard Stikita-compatible random orbital and disc sanders

Compatibility

Designed for use with Stikita-compatible 5 inch disc sanders and random orbital tools used in metal fabrication, composites finishing, and general surface preparation applications.

Installation Notes

Installation and disc changes should be performed with the sander powered off and disconnected from its power source. Align the Stikita backing to the pad and press firmly before operation. Inspect the disc for tears or edge damage before each use and replace immediately if damage is found. Follow applicable shop safety protocols including eye protection and dust control when operating abrasive discs.
