DIAMOND DISCS TYPES AND USES
Low cost per
tion. Less disc
Cool a diamond disc continually with water to
prevent overheating, which can cause the disc
to break and pieces being thrown off resulting
in injury and damage.
Using diamond discs
Proceed as follows:
• Let the disc rotate in the same direction as the arrow
• Cool continually with water.
• Keep the disc sharp.
• Remove the disc when transporting the cutter.
• Running the disc in the wrong direction.
• Forcing a dull disc or wedging the disc into a cut.
• Transporting the cutter with the disc fitted.
• Letting the disc fall on the work piece.
Dry diamond discs
Dry diamond discs are a new generation of discs that do not
require water cooling. However, the discs are still damaged by
excessive heat. It is good economics to let the disc cool by
simply lifting the disc from the cut every 30–60 seconds and let
it cool for 10 seconds.
