3M 7000045178 Abrasive Disc 80 Grit 2 Inch Cubitron Ii

Product Description

The 3M 7000045178 is a coated abrasive disc engineered for medium to high pressure grinding on demanding workpiece materials. Part of the Cubitron II 984F series, it uses 3M Precision-Shaped Grain (PSG) technology to maintain sharp cutting points throughout the disc life, delivering fast material removal with less applied pressure. The 2-inch diameter and Roloc quick-change attachment make it well-suited for tight access areas and detailed edge work. At 80 grit, it removes material aggressively while a built-in grinding aid helps control heat buildup on heat-sensitive alloys.

This disc is designed for use on stainless steel, cobalt chrome, and nickel alloys — materials common in fabrication, aerospace component work, and precision machining environments. The Roloc attachment system allows rapid disc swaps between grits or applications without additional hardware. The 2-ply backing construction adds durability specifically for edge grinding tasks where backing failure is a common problem with single-ply alternatives.

Key Features

• Precision-Shaped Grain (PSG) maintains sharp cutting points for fast, consistent stock removal
• Grinding aid incorporated into the disc reduces heat generation on stainless steel and other heat-sensitive alloys
• Roloc quick-change attachment enables fast disc changes between grades or applications
• 2-ply backing construction provides added durability for edge grinding work
• 80 grit rating suited for medium to aggressive material removal
• 2-inch diameter fits compact angle grinders and die grinders for confined-space access

Compatibility

Compatible with Roloc-style quick-change disc holders and compatible rotary tools accepting 2-inch Roloc attachments. Performs on stainless steel, cobalt chrome, and nickel alloy workpieces.

Installation Notes

Installation and disc changes should be performed by qualified grinding or fabrication personnel following applicable shop safety protocols. Ensure the grinder is powered off and the wheel has come to a complete stop before attaching or removing the disc. Verify the tool RPM rating meets or exceeds the disc speed rating prior to use. Eye protection, hearing protection, and appropriate gloves are standard PPE for grinding operations.
