A diamond is the hardest substance known to man and
properly handled will do a tremendous amount of work. But, diamond is brittle and a moment of carelessness can
ruin an expensive tool.
Never Quench a Hot Diamond with Water
The sudden change in temperature may shatter the diamond.
Always let a hot diamond cool naturally. Coolant should be turned on before the dressing operation is started.
A grinding wheel that is used wet, should always be dressed wet.
If dressing must be done dry, take light cuts. Allow plenty of time for the diamond to cool between passes. Prolonged
dry dressing causes diamond burning and fractures.
Never Force the Diamond Into the Wheel
The shock of meeting a fast revolving wheel suddenly
may splinter the diamond and may cut a deep groove in the wheel.
