A more durable abrasive allows these wheels to remove more material and last longer than Norton General Purpose Grinding Wheels. They are also known as Type 1 wheels and straight wheels.

The porous bond leaves more space between abrasive grains so heavy amounts of chips and coolant easily flow through.

The small 3/32" diameter shank and small head makes these bits good for precise and intricate jobs.

With more flaps than standard discs, these last 30-40% longer.

The flaps have an abrasive to remove material and a lubricant that minimizes heat to reduce discoloration of the work surface.

The flaps wrap around the outer edge of these discs to sand welds at right angles.
