3M 7100310796 Fiber Disc 5 in 36 Grit Gl Quick Change Ceramic

Product Description

The 3M 7100310796 is a 5-inch coated abrasive fiber disc designed for aggressive material removal on metal, weld seams, and hard surfaces. It uses a Precision Shaped Ceramic grain bonded with a resinoid bond to a fiber backing, producing consistent cut rates and extended disc life compared to conventional ceramic or aluminum oxide options. The GL Quick Change attachment system allows fast, tool-free disc swaps on compatible random orbital and right-angle grinders. Rated to 12,000 RPM, this disc is suited for fabrication shops, maintenance welding, and structural steel prep work. It is sold individually with a minimum order quantity of 25 units per order.

This disc is built for heavy stock removal and surface conditioning applications on ferrous metals, stainless steel, and other hard materials. The 36 grit designation makes it appropriate for weld blending, deburring, edge chamfering, and scale removal in industrial fabrication and maintenance environments. The purple fiber backing and precision grain geometry help manage heat buildup during extended grinding, making it a practical choice for production grinding tasks where disc consistency matters across a full shift.

Key Features

• Precision Shaped Ceramic grain delivers high cut rate and longer service life than conventional abrasives
• GL Quick Change attachment for fast disc changes without additional tooling
• 36 grit for aggressive stock removal, weld blending, and scale removal
• Resinoid bond on fiber backing provides durability under load
• 12,000 RPM maximum speed rating suits standard right-angle grinders
• Purple disc color identifies the 1187C series for easy shop inventory management

Compatibility

Designed for use with GL Quick Change right-angle grinders and random orbital tools that accept 5-inch fiber discs with the GL attachment style. Verify that the grinder spindle speed does not exceed the 12,000 RPM disc rating before use.

Installation Notes

Installation and disc changes should be performed by qualified personnel with the grinder fully powered down and disconnected from its power source. Mount the disc securely to the GL Quick Change hub before resuming operation and confirm the hub and backing pad are free of damage. Always wear appropriate PPE including face shield and gloves when operating grinding equipment. Follow ANSI B11 and applicable OSHA standards for abrasive wheel use.
