A 6-ounce, 0.3 hp 201SV spindle from Air Turbine Tools with a point stone tool is shown here being used to hand-deburr aluminum castings at a constant rotational speed of 65,000. This model requires just a light touch as its speed does the cutting. The light touch, combined with low vibration and weight, reduces the risk of stress injuries such as carpal tunnel syndrome for operators while a brake option stops coast rotation in seconds.
