Walter 1-Inch to 7/8-Inch Arbor Adapter Bushing (2-Pack)

Get the Perfect Fit for Your Grinder

As a welder or fabricator, you know the frustration of reaching for a fresh grinding wheel only to find that the arbor hole is too big for your machine. It’s a common issue in shops that use a mix of equipment or buy abrasives in bulk. The Walter 1" to 7/8" Bushing (Pack of 2) is the simple, effective solution to this problem. These handy adapters allow you to mount wheels with a 1-inch center hole onto your standard 7/8-inch angle grinder or bench grinder shaft instantly.

Don't let a mismatched size stop your work or force you to run to the supply store. With these Walter bushings in your toolbox, you can adapt your inventory on the fly. They are designed to slide easily into the wheel's arbor hole, creating a snug fit that centers the wheel perfectly on your tool's spindle. This is crucial for preventing the "wobble" that happens with poor fitment—wobble that can shatter wheels, ruin your workpiece, or cause operator fatigue due to excessive vibration. With Walter's precision manufacturing, you get a smooth, balanced spin every time.

This pack includes two bushings, so you can outfit multiple wheels or keep a backup in your pocket. They are lightweight, durable, and built to withstand the rigors of daily shop use. Whether you are working with cutoff wheels, grinding discs, or wire brushes that have the larger 1-inch opening, these adapters bridge the gap. They are compatible with most major brands of abrasives and grinders, making them a universal fix for a common shop headache.

Walter Surface Technologies is known for building products that help fabricators work better and safer. These bushings are no exception. Instead of risking your safety by trying to center a wheel manually or using makeshift shims, use the proper tool for the job. These bushings ensure your locking nut clamps down securely and the wheel stays true, letting you focus on laying perfect beads and getting the perfect finish.
