PRETEC Flap Discs 4 1/2 for Angle Grinder 40 Grit Type 27, 12PCS

Key Features

• Built with premium zirconia abrasive at high density, these flap discs deliver faster material removal and longer wear life compared to conventional aluminum oxide options—keeping you working longer between disc changes.
• The aggressive 40-grit formulation makes quick work of heavy stock removal across steel, cast iron, stainless steel, wood, and other materials. Ideal for grinding down weld seams, smoothing sharp edges, refinishing surfaces, or stripping away rust.
• A resin fiber build reinforced with a rugged fiberglass backing plate gives each disc added structural strength. Even under heavy load, the disc maintains its shape for consistent, vibration-free grinding results.
• The T27 beveled shape allows working angles between 5 and 15 degrees, giving you the flexibility needed for precise edge grinding and detailed corner finishing.
• Each disc measures 4.5 inches with a 7/8-inch arbor and fits most standard 4.5-inch angle grinders, rated for speeds up to 13,300 RPM. This 40-grit set delivers professional-grade performance—suited for workshops, shipyards, pipeline work, and industrial upkeep.
