08D452 - Walter 4.5-Inch Concrete and Masonry Grinding Wheel

Specialized Abrasive for Masonry and Cast Iron

The Walter Concrete 4-1/2" x 1/8" C-24 Grinding Wheel (SKU: 08D452) is a high-performance abrasive solution engineered specifically for the unique demands of working with concrete, masonry, stone, and cast iron. Unlike standard aluminum oxide wheels designed for steel, this wheel utilizes premium silicon carbide grains (C-24). Silicon carbide is harder and sharper, making it the ideal abrasive medium for cutting and grinding non-ferrous materials and brittle substrates like stone and concrete. The coarse 24-grit composition ensures rapid material removal, allowing operators to shape, smooth, or cut through tough masonry materials efficiently.

One of the defining technical characteristics of this wheel is its 1/8-inch thickness combined with a heavily reinforced bonding matrix. Standard cutting wheels are typically 1/16-inch or thinner and cannot safely handle the side pressure exerted during grinding. Conversely, standard grinding wheels are 1/4-inch thick, which makes them too slow and wasteful for cutting. The 08D452 bridges this gap, offering a robust 1/8-inch profile that is thin enough for effective cutting but structurally reinforced to withstand intermittent light grinding (side loading). This dual capability makes it an invaluable tool for contractors who need to switch between cutting pavers and smoothing rough concrete edges without the downtime of changing wheels.

Safety and durability are paramount in the design of Walter's Concrete series. The wheel features multiple layers of reinforcement that maintain structural integrity even under the high stress of grinding hard cast iron or uneven concrete surfaces. The bond is formulated to resist loading, preventing the wheel from glazing over when working with softer, porous materials. This ensures consistent cutting action throughout the life of the wheel. Whether used for surface preparation, removing mold marks from cast iron, or cutting masonry block, the Walter 08D452 delivers professional-grade performance and reliability.
