DEWALT HP Cutting Wheel 4-1/2 In x 0.045 In x 7/8 In Aluminum Oxide DW8424
Description
The DEWALT DW8424 HP Cutting Wheel measures 4-1/2 inches across with a 7/8-inch arbor, sized for standard angle grinders. Temper Point grain technology holds a sharp edge well past the point where conventional abrasives dull, and the enhanced adhesion between coated grains and the resin bond keeps that edge intact under heavy pressure. The depressed-center design and A60T specification suit fabrication and industrial maintenance work, from angle iron and rebar to thick plate and pipe. Rated 4.7 out of 5 stars across more than 1,280 reviews, the wheel earns 81% five-star ratings from tradespeople cutting metal daily. DEWALT positions the HP Series above its General Purpose line, with heavier-duty grain and a longer-lasting bond, but below the per-wheel cost of the ELITE ceramic wheels.
