3M 7000144102 Abrasive Disc 80 Grit 1 Inch Cubitron Ii 984F

Product Description

The 3M 7000144102 is a coated abrasive disc designed for medium to high pressure grinding on metal workpieces where a compact disc size is required. Built on the Cubitron II 984F platform, it uses 3M Precision-Shaped Grain (PSG) technology that maintains sharp cutting points throughout the disc life, delivering fast material removal with reduced operator pressure. The 2-ply backing adds durability for edge grinding work, and an integrated grinding aid helps control heat at the workpiece surface. Metalworking fabricators and tool-and-die shops are the primary installers and users of this disc.

This disc is suited for grinding stainless steel, cobalt chrome, and nickel alloys in applications where heat generation is a concern. The 1-inch diameter makes it practical for tight-access grinding, contouring, and edge work on smaller components. It mounts via the Roloc quick-change attachment system, allowing fast swaps between grit grades or applications without tools. Typical use scenarios include weld blending, deburring, and surface preparation on heat-sensitive alloy parts in fabrication and manufacturing environments.

Key Features

• Precision-Shaped Grain (PSG) technology delivers fast cutting with reduced grinding pressure
• Integrated grinding aid minimizes heat buildup 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 swaps between grades or tasks
• Compact 1-inch diameter suits tight-access and small-component grinding work
• 80 grit rating targets medium stock removal and surface blending

Compatibility

Designed for use with Roloc-compatible right-angle grinders and die grinders that accept 1-inch quick-change abrasive discs.

Installation Notes

This disc is installed by metalworking professionals using Roloc-compatible pneumatic or electric grinders. Ensure the grinder is powered off and air supply is disconnected before changing discs. Verify that the grinder RPM rating meets or exceeds the disc RPM rating before operation. Wear appropriate PPE including face shield, gloves, and hearing protection during grinding operations.
