The CGW 70143 is an 8-inch diameter, 1-inch thick, 3-inch arbor/cone wheel designed for general metal polishing and surface finishing applications. This medium grade convolute wheel uses aluminum oxide abrasive, offering a balanced combination of cut rate and durability suitable for shaping and refining workpieces where the surface needs to be kept true without altering overall dimensions significantly. The convolute construction provides multiple abrasive layers bonded in a stacked, radial fashion, contributing to a longer service life by presenting fresh abrasive surfaces as the wheel wears.
Key characteristics include its 8A aluminum oxide grain, which is a common choice for versatile metalworking tasks, and its rated operating speed of up to 4500 RPM. The medium grade indicates a moderate aggressiveness appropriate for achieving intermediate removal rates while minimizing heat buildup and loading on the wheel during use. Convolute wheels like this are designed to resist heat and loading that can occur when working with metals that tend to smear or clog abrasives, helping maintain consistent finishing performance over time.
Ideal use scenarios include deburring, edge rounding, and finishing operations on metal components where maintaining precise dimensions is important. The wheel’s size and arbor/shank compatibility should be matched to compatible right-angle grinders or tool mounts that accept a 3-inch arbor, ensuring secure mounting and stable operation. When selecting this wheel, confirm compatibility with your equipment’s spindle or grinder profile, RPM rating, and mounting method, and follow relevant safety and operating guidelines during wheel installation and use.
