Flap Disc 4 1/2 -7/8 Arbor 80 Grit

Flap Disc – 4-1/2", 7/8" Arbor, 80 Grit

Smooth finishing and precision surface prep in one disc. The Flap Disc 4-1/2" 80 Grit delivers controlled abrasion for smoothing welds, blending surfaces, and preparing metal for painting or coating — with less aggressive cutting than coarser grits for a cleaner, more refined finish. Overlapping abrasive flaps conform to flat and contoured surfaces. Fits standard 4-1/2" angle grinders with a 7/8" arbor.

Key Features

• 80 grit — medium for smooth finishing and controlled surface prep after coarser grinding
• 4-1/2" diameter with 7/8" arbor for standard angle grinder compatibility
• Overlapping flap design conforms to flat and contoured surfaces for consistent results
• Flaps wear away to expose fresh abrasive, extending disc life compared to grinding wheels
• Ideal as a finishing step after 36 or 60 grit grinding

Common Applications

• Weld seam smoothing and blending
• Surface finishing before priming or painting
• Light rust removal and surface cleanup
• Metalworking and automotive fabrication finishing
