3M 7000046856 Quick Change Fe Disc 1.5 in Aluminum Oxide

Product Description

The 3M 7000046856 is a Quick Change Surface Conditioning FE disc designed for one-step workpiece preparation ahead of final finishes and coatings. Built on an open-web FE substrate with aluminum oxide abrasive, this disc delivers high initial and extended cut rates at up to 20,000 rpm. At 1.5 inches in diameter, it is sized for detail work and edgework on smaller workpieces. Licensed HVAC technicians, fabricators, and metalworking professionals install and swap these discs using quick-change tooling, reducing downtime between tasks. The open-web construction responds to surface irregularities and minimizes gouging during aggressive stock removal operations.

This disc is engineered for use on ferrous metals, stainless steel, and high nickel and chrome alloys. It excels in applications that demand high contact pressure and efficient material removal, including deburring sharp edges, blending welds, and surface prep on flat and contoured workpieces. Typical installation scenarios include fabrication shops, maintenance environments, and field metalwork where consistent surface conditioning is required before painting, coating, or further finishing. The quick-change attachment system allows fast disc swapping without additional tools, maintaining workflow on production or service jobs.

Key Features

• Aluminum oxide abrasive on FE material provides high initial and sustained cut rate for efficient stock removal
• Open-web substrate responds to surface irregularities and reduces gouging risk on finished or precision workpieces
• High edge durability and flexibility make it effective for edgework and contoured surfaces
• Rated to 20,000 rpm for compatibility with standard high-speed rotary quick-change tools
• Quick-change fastening system enables rapid disc swapping to maintain tool productivity
• Available in coarse brown, medium maroon, and very fine blue grades to match prep requirements

Compatibility

Designed as a standard-style replacement and service disc for quick-change rotary tools accepting 1.5-inch diameter surface conditioning discs; consult tool documentation to confirm arbor and speed compatibility before use.

Installation Notes

Installation is performed by metalworking and fabrication professionals using compatible quick-change rotary tools. Verify the tool spindle speed does not exceed the 20,000 rpm disc rating before mounting. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or distortion. Follow applicable shop safety protocols including eye protection and guarding requirements when operating abrasive disc tools.
