Example: Tool rated at 6000 R.P.M.
90% of 6000 (.90 x 6000) = 5400
95% of 6000 (.95 x 6000) = 5700
The tool should run between 5400 and 5700 when tested with a tachometer.
Mounting Abrasives
The mounting of the abrasive used with the tool is very important to ensure safety for the operator
and proper functioning of the tool. There are strict rules for mounting wheels that are outlined in ANSI
B7.1-2000. The following diagrams briefly describe the methods and equipment for mounting most
abrasives.
