CGW 34007 20" X 1" X 8" T1 83A-60J 60-Grit White Aluminum Oxide Surface Grinding Wheel

The CGW 34007 is a 20 inch by 1 inch by 8 inch T1 surface grinding wheel designed for heavy stock removal with a precise finish. This wheel uses white aluminum oxide grain, identified as 83A, and features a 60 grit size with a J hardness rating, suited for workpieces where a balance of cutting action and dimensional control is required. The 60-grit, white aluminum oxide composition provides a predictable cutting profile and finish on a range of materials, including heat-sensitive steels, making it a practical choice for shops performing surface grinding tasks that demand both efficiency and accuracy.

Key construction details include a 20" diameter, 1" thickness, and an 8" arbor/shank size, with a T1 type designation that aligns with specific grinder configurations. The combination of grain type and grit results in a wheel that can engage material with controlled aggressiveness, supporting easy cutting action while still achieving a refined surface. The wheel is packaged as an individual item, with packages available in multiples for bulk purchases.

When selecting grinding wheels, consider the material being ground, the desired surface finish, and the machine’s speed compatibility. This CGW wheel is rated for use at an RPM around 1623, aligning with typical heavy stock-removal operations on compatible grinders. Proper mounting and truing ensure the wheel runs true and delivers consistent results, and regular inspection for glazing or glazing-free surfaces helps maintain cutting efficiency over time.
