Flap Disc 4 1/2 -7/8 Arbor 40 Grit

Flap Disc – 4-1/2", 7/8" Arbor, 40 Grit

Aggressive grinding with a slightly finer bite than 36 grit. The Flap Disc 4-1/2" 40 Grit features overlapping abrasive flaps for fast, consistent material removal on rust, weld spatter, paint, and rough metal surfaces — while conforming to contoured surfaces better than a standard grinding wheel. Fits standard 4-1/2" angle grinders with a 7/8" arbor.

Key Features

• 40 grit — coarse for aggressive material removal with slightly more control than 36 grit
• 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
• Combines grinding and finishing in a single disc for faster workflow

Common Applications

• Rust, weld spatter, and paint removal
• Weld seam grinding and blending
• Metal fabrication and surface preparation
• Heavy material removal on flat and contoured metal surfaces
