Dewalt DARB1G0805 Fiber Resin Disc 4.5in 80 Grit 5PK

Product Description

The DEWALT DARB1G0805 is a coated abrasive fiber resin disc designed for aggressive material removal on metal and other hard surfaces. Measuring 4.5 inches in diameter and rated at 80 grit, this disc cuts with aluminum oxide abrasive bonded to a fiber resin backing for durability under load. The 80-grit classification places it in the medium-coarse range, suited for weld blending, surface prep, and stock removal. Each order contains 5 discs. These are consumable grinding accessories used with compatible angle grinders and disc grinders common in fabrication, mechanical, and trade service work.

These discs are appropriate for residential and commercial job sites where metal grinding, rust removal, weld seam blending, and surface conditioning are required. Electricians, pipefitters, HVAC technicians, and general mechanical contractors frequently use 4.5-inch fiber resin discs during equipment installation and structural prep work. The aluminum oxide abrasive construction makes these discs a practical choice for ferrous metals including mild steel and cast iron applications.
