3M 7000045170 Abrasive Disc 36 Grit 3 Inch Cubitron Ii

Product Description

The 3M 7000045170 is a coated abrasive disc designed for medium to high pressure grinding applications where a compact disc size is required. Built around 3M Precision-Shaped Grain (PSG) technology, the disc maintains sharp cutting points throughout its service life, delivering fast material removal with reduced operator pressure. The 984F construction includes an integrated grinding aid that limits heat buildup during grinding, making it well suited for heat-sensitive alloys. At 3 inches in diameter with a 36-grit rating, this disc is installed by fabricators, welders, and metal finishers working in production or job-shop environments.

This disc is engineered for stainless steel, cobalt chrome, and nickel alloy grinding applications where edge work and precision stock removal are priorities. The Roloc quick-change attachment system allows fast disc swaps between grit grades or applications without additional tooling. The 2-ply backing construction supports aggressive grinding pressures while maintaining disc integrity during edge-contact work. Typical use cases include weld blending, surface conditioning, and edge grinding on fabricated metal components.

Key Features

• 3M Precision-Shaped Grain (PSG) sustains sharp cutting points for fast, consistent stock removal
• Integrated grinding aid reduces heat generation on stainless steel and heat-sensitive alloys
• 2-ply backing construction supports medium to high pressure grinding and edge work
• Roloc quick-change attachment system enables fast disc changes between grades or applications
• Coated abrasive construction rated at 36 grit for aggressive material removal
• Compact 3-inch diameter suits applications where larger discs cannot reach

Compatibility

Compatible with Roloc-style quick-change disc holders and angle grinders equipped with a Roloc mandrel. Suited for grinding stainless steel, cobalt chrome, and nickel alloy workpieces.

Installation Notes

Installation requires a compatible Roloc mandrel threaded into an angle grinder or die grinder rated for the disc speed. Inspect the disc for damage before mounting and confirm the tool RPM rating meets or exceeds the disc maximum speed rating. Always wear appropriate eye, face, and hand protection during grinding operations. Disconnect or de-energize the tool before mounting or removing the disc.
