Balboa Supply offers a full range of grinding wheels, whether it is a basic cutoff wheel, a gumming wheel or a wheel that is manufactured to your particular specifications. For the past 25 years we have specialized in spec wheels for the aerospace industry.
If you are trying to replace an existing wheel, take a look at the chart below for easier reorders. Often, a slight change in the grit size, structure or hardness may reduce burning or loading, while improving the efficiency of the wheel.
We also have dressers to reduce loading and for keeping a desired wheel profile.
