• Quality aluminum oxide abrasive designed for cutting alloys, steels and ferrous metals • Side reinforced with harder grade which is ideal for long life cutting small cross-section workpieces • Abrasive and bond combination designed for smooth clean cut on low HP machines • Excellent blend of performance and low price • Wheels should only be use on chop saw machines and should not go on portable cut-off machines • A chop saw is a light, low horsepower portable machine. These machines can be easily moved, but the workpiece is carried to the machine. Chop saw cut-off wheels are designed specifically for this machine with finer grit, softer grades, and reinforcement layers that match the application.
