3M 7010329805 Scotch-brite Bf-dc Disc 12 in Ao Medium

Product Description

The 3M 7010329805 Scotch-Brite BF-DC Blend and Finish Disc is a surface conditioning abrasive disc designed for weld burn removal, deburring, rust removal, blending, and finishing on metal workpieces. Built on a load-resistant open web construction with aluminum oxide medium grade mineral, it delivers aggressive material removal while leaving a consistent satin finish. The springy nonwoven fibers conform to irregular surfaces, producing uniform results across contoured and flat stock alike. This disc measures 12 inches in diameter with a 1-1/4 inch arbor and is sold individually.

This disc is suited for metalworking applications in fabrication shops, manufacturing facilities, and maintenance environments. It is well matched to tasks such as removing weld discoloration, light rust, and small burrs from steel and other metals prior to finishing or coating. The open web construction resists loading, extending disc life in heavy-use conditions. Discs can be run individually or stacked on a straight shaft tool or bench motor to increase the effective cleaning surface width for broader coverage.

Installation Notes

Installation and disc changes should be performed by a qualified operator with the tool fully powered down and unplugged or locked out per applicable OSHA lockout/tagout procedures. Verify the tool spindle speed rating meets or exceeds the maximum rated speed of the disc before mounting. Inspect the disc for damage before each use and do not operate a disc that shows tears, separation, or deformation. Eye protection and appropriate PPE are required during operation.
