The Flex-Hone for Rotors should be securely held in a collet, chuck or similar holding device. The disc rotor should
be mounted on a brake lathe and rotated between 125 and 210 RPM. Position all guards before starting the tool.
The tool should be chucked securely in a variable speed electric drill motor or low speed air drill. The tool should
rotate 300-600 RPM. (never exceed 1000 RPM). Bring the tool into contact with the rotating rotor at a slight
angle and work in towards the center and out to the edge of the rotor face. Light, uniform pressure is used. Dwell
time against the part produces the desired finish not excessive pressure. The tool is used dry and should be worked
for 15 to 20 seconds at a time. Do not overheat by dwelling for longer periods of time. 10-15 seconds clockwise
and 5-10 seconds counterclockwise should produce the desired finish.

over 200 sets of rotors, conclusion of test
indicated this tool is a great idea; and cheaper
to use over a long period of time, than other
