3M 7000119220 Cubitron Ii 984F Disc 4 Inch 80 Grit

Product Description

The 3M 7000119220 is a Cubitron II Roloc 984F Durable Edge coated abrasive disc designed for medium to high pressure grinding on a 4-inch platform. It uses 3M Precision-Shaped Grain (PSG) technology, which maintains sharp cutting points throughout the disc life, allowing faster stock removal with less applied pressure. The 2-ply backing construction adds durability for edge grinding work, and an integrated grinding aid helps control heat buildup during aggressive grinding cycles. Licensed HVAC and metalworking professionals will find this disc particularly effective on heat-sensitive base metals.

The 7000119220 is suited for stainless steel, cobalt chrome, and nickel alloy fabrication and finishing work. The 80-grit rating positions it in the medium-coarse range, appropriate for stock removal, weld blending, and surface conditioning in tight or contoured areas where a smaller disc is required. The Roloc quick-change attachment system allows fast disc swaps between grits or applications without additional tooling, reducing downtime during production runs.

Key Features

• Precision-Shaped Grain (PSG) maintains sharp cutting points for fast stock removal with reduced pressure
• Grinding aid minimizes heat generation on stainless steel and other heat-sensitive alloys
• 2-ply backing construction provides added durability for edge grinding applications
• Roloc quick-change attachment system enables tool-free disc changes between grades
• 4-inch diameter suits confined or contoured grinding locations where larger discs cannot reach

Compatibility

Designed for use with Roloc-compatible angle grinders and die grinders accepting 4-inch quick-change abrasive discs. Optimized for grinding stainless steel, cobalt chrome, and nickel alloys under medium to high pressure conditions.

Installation Notes

Attachment and removal of Roloc discs requires only a twist-and-lock motion; ensure the backup pad is clean and undamaged before mounting. Verify the grinder RPM rating meets or exceeds the disc maximum speed before operation. Always wear appropriate personal protective equipment including eye protection and gloves when operating abrasive discs. Inspect the disc for damage before each use and discard any disc that shows cracking, fraying, or delamination.
