3M 7010330830 Non-woven Buff Blend Hs Disc 12 Inch Ao

Product Description

The 3M 7010330830 is a high-strength non-woven nylon abrasive disc engineered for light deburring, surface cleaning, and final finishing on metal workpieces. The disc measures 12 inches in diameter with a 1-inch arbor center hole and uses Aluminum Oxide mineral for consistent, sharp cutting action across ferrous and non-ferrous metals. The dense, stiff HS construction resists folding under pressure, and the open web design stays load-resistant to limit debris buildup and extend service life. Metalworkers, fabricators, and finishing technicians install this disc on bench grinders or finishing machines where a controlled, smear-free surface finish is required.

This disc is suited for production finishing and light deburring on metal surfaces in both shop and field environments. The open web construction conforms to irregular surfaces and edges without gouging the substrate, making it practical for edgework and contoured parts. It is available in three grades: Coarse (CRS, green), Medium (MED, blue), and Very Fine (VFN, maroon), allowing the operator to select the appropriate level of aggressiveness for the task. Typical applications include pre-paint prep, weld cleanup, and final polish passes on machined components.
