Grinding Wheel Selection

Use grinding wheels, and accessories that are:
• correct size as written on tool's nameplate.
• rated at or above the RPM listed on the tool's name-
plate.
• correct accessory, wheel type and grit for the job.
Grinding is the cutting action of thousands of abrasive
grains on the face of a grinding wheel. When grinding
metals such as steel and iron, choose an aluminum
oxide grinding wheel. Select a silicon carbide grinding
wheel for stone and concrete. Use cotton reinforced
wheels for non-ferrous metals.
Type 1 Reinforced 1/8" thick or less Cut-Off Wheels
are suited for small cut-off and shallow notching
operations only. Always handle wheels carefully to
avoid damage. Before installing any wheel, always
inspect it for cracks. If wheel is cracked, discard it to
prevent others from using it.
Care of Grinding & Cut-Off Wheels
Grinding/cut-off wheels should be protected from:
• wetness and extreme humidity
• any type of solvent
• extreme changes in temperature
• dropping and bumping
Grinding and cut-off wheels should be stored:
• in an organized way so wheels can be removed
without disturbing or damaging other wheels
• with their safety information
Grinding and cut-off wheels should NOT be dropped,
rolled or bumped.
Discard wheels that have been dropped, rolled,
bumped, subjected to extreme changes in tempera-
ture, or come into contact with solvents or wetness.
Only use accessories with Maxi-
WARNING
mum Safe Operating Speed rated
at least equal to the maximum speed marked on
