3M 7100064175 Hook Loop Disc 5 in 150 Grit Ceramic

Product Description

The 3M 7100064175 is a 5-inch hook and loop abrasive disc engineered for fine-grit surface preparation and finishing work. Part of the 3M 775L Series, it uses a ceramic abrasive grain on a coated backing to deliver consistent stock removal with reduced loading. At 150 grit, this disc falls in the fine grade range, making it well suited for finish sanding passes on wood, composites, and painted surfaces. The hook and loop attachment system allows for quick disc changes without adhesive-backed alternatives. Installers and finishing professionals can swap discs on compatible 5-inch random orbital or disc sanders with minimal downtime.

This disc is used in light industrial, woodworking, automotive finishing, and general surface prep applications. It is a single-disc unit, appropriate for bench stock replenishment or spot replacement. The 150-grit ceramic construction handles both hardwood and softwood surfaces, as well as primed or painted panels requiring smoothing between coats. Ceramic abrasive grain maintains cutting efficiency longer than aluminum oxide alternatives under moderate pressure, reducing the frequency of disc changes during extended finishing runs.

Key Features

• 150 grit fine grade ceramic abrasive for consistent finish-pass material removal
• 5-inch disc diameter fits standard 5-inch hook and loop random orbital sanders
• Coated abrasive construction minimizes loading on wood and painted surfaces
• Hook and loop backing enables fast, tool-free disc changes
• Part of the 3M 775L Series for reliable ceramic grain performance

Compatibility

Designed as an OEM-style replacement or stock disc for use with 5-inch hook and loop random orbital and disc sanders in woodworking, finishing, and light industrial applications.

Installation Notes

Installation requires no tools — align the hook and loop backing to a compatible 5-inch sanding pad and press firmly to seat. Ensure the sander is powered off and unplugged before changing discs. Inspect the backing pad for worn hooks before mounting a new disc, as degraded pads reduce grip and can cause disc separation during use. Dispose of worn discs per local waste guidelines.
