3M 7000044905 Cubitron Ii Roloc Fibre Disc 982C 80 Grit

Product Description

The 3M 7000044905 is a 2-inch Cubitron II Roloc Fibre Disc in the 982C series, designed for medium to high pressure grinding on carbon steel. It uses 3M Precision Shaped Grain (PSG) technology, which maintains sharp cutting points to remove material quickly with less applied pressure. The stiff fiber backing and strong resin bond hold up under demanding conditions such as weld grinding and heavy stock removal. This disc is grit 80, making it well suited for aggressive material removal while keeping heat generation low. Licensed tradespeople and fabricators working in weld prep, deburring, and surface conditioning applications reach for this disc when a compact, fast-cutting option is required.

This disc is intended for use on angle grinders and die grinders equipped with a Roloc-compatible backup pad. The 2-inch diameter makes it practical in tight spaces and on smaller weld joints where a larger disc would be difficult to control. Carbon steel is the primary substrate, though the cooler-running PSG abrasive also reduces the risk of heat-induced discoloration and stress cracking on finished or semi-finished workpieces. Metal fabricators, pipe fitters, and ironworkers will find this disc useful for production grinding scenarios where frequent disc changes slow output.

Key Features

• Precision Shaped Grain (PSG) cuts fast with less pressure, reducing operator fatigue
• Cooler running abrasive minimizes metal discoloration, oxidation, and heat-related stress cracks
• Stiff fiber backing and strong resin bond provide durability for high-pressure weld grinding
• Roloc attachment system allows quick disc swaps between grits or applications without tools
• Extended disc life means fewer changes per job and lower cost per part

Compatibility

Designed for use with Roloc-compatible backup pads on angle grinders and die grinders rated for 2-inch abrasive discs. Intended for grinding on carbon steel substrates.

Installation Notes

This disc is installed and serviced by metalworkers and fabricators using standard angle grinders or die grinders with a Roloc-style backup pad. Always power down and disconnect the grinder before mounting or removing the disc. Confirm the grinder RPM rating meets or exceeds the maximum RPM marked on the disc before operation. Wear appropriate personal protective equipment, including face shield and gloves, during use.
