3M 7000118303 Abrasive Disc 36 Grit 3 Inch Ceramic

Product Description

The 3M 7000118303 is a coated abrasive disc designed for stock removal and finishing applications across metalworking and fabrication trades. It measures 3 inches in diameter and cuts at 36 grit using a blend of 3M ceramic and aluminum oxide abrasive grain. The ceramic mineral self-sharpens during use, extending disc life and maintaining a consistent cut-rate. A heat-resistant resin bonds the abrasive to a heavy polyester backing rated for medium-pressure work in both wet and dry conditions. A grinding aid is incorporated to reduce heat buildup, making this disc suitable for heat-sensitive alloys including stainless steel, nickel alloys, and titanium.

This disc is suited for metal fabrication, weld blending, surface prep, and finishing on ferrous and non-ferrous metals. It is commonly used in production grinding environments where consistent stock removal rates matter. The water-resistant polyester backing allows use with coolant or in wet grinding setups. Machinists, fabricators, welders, and metalworking technicians are the primary installers and users of this disc.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for improved durability and cut-rate over aluminum oxide alone
• Grinding aid reduces grinding temperatures for use on stainless steel, nickel alloys, and titanium
• Heavy polyester backing supports medium-pressure applications and maintains consistent performance in wet and dry conditions
• Heat-resistant resin bonding provides durability under pressure, heat, and water exposure
• Roloca attachment system allows efficient and secure disc attachment and removal

Compatibility

Designed for use with Roloca-compatible right-angle grinders and disc holders that accept 3-inch coated abrasive discs.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or air supply disconnected. Verify the backing pad or holder is rated for the disc diameter and operating speed before mounting. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or unusual wear. Follow applicable ANSI B11 and OSHA abrasive wheel safety standards when operating grinding equipment.
