3M 7100281840 Abrasive Disc 6 Inch 180 Grit Ceramic 250/CS

Product Description

The 3M 7100281840 is a coated abrasive disc engineered for demanding surface preparation and finishing work. Built on the Cubitrona II Stikita platform, it uses precision shaped ceramic mineral bonded with resin to a J-weight cloth backing. The PSA (pressure-sensitive adhesive) attachment system allows fast disc changes on compatible random orbital and disc sanders. The open coat construction resists loading, extending disc life on wood, composites, and metal. At 6 inches in diameter with a grit rating of 180 and above, this disc is suited to fine finishing passes and light stock removal by fabricators, woodworkers, metal finishers, and industrial maintenance trades.

This disc is used in industrial, manufacturing, and trade finishing environments where a consistent fine finish is required after earlier aggressive cut stages. The 6-inch format fits standard PSA backup pads on pneumatic and electric random orbital sanders. The open coat and ceramic abrasive combination performs well on heat-sensitive substrates and hard alloys where conventional aluminum oxide discs load prematurely. Cases contain 250 discs, supporting high-volume production use.

Key Features

• Precision shaped ceramic mineral delivers consistent cut and extended disc life compared to conventional abrasives
• PSA backing enables quick disc swaps on compatible 6-inch backup pads
• Open coat construction reduces loading on wood, composites, and soft metals
• J-weight cloth backing provides flexibility for contoured surface work
• Resin bond withstands heat generated during high-speed grinding and finishing
• Maximum operating speed of 10000 RPM suits standard pneumatic and electric disc sanders

Compatibility

Designed for use with standard 6-inch PSA backup pads on pneumatic and electric random orbital sanders used in industrial finishing, fabrication, and trade surface preparation applications.

Installation Notes

This disc is installed by pressing the PSA face firmly onto a clean, dry 6-inch backup pad — contaminants on the pad face will reduce adhesion and shorten disc life. Do not exceed the rated maximum speed of 10000 RPM. Inspect the backup pad for tears or deformation before mounting; a damaged pad can cause uneven wear or disc separation. Always wear appropriate eye and face protection when operating abrasive discs at speed.
