One of the most frequent misconceptions about diamonds are that they are the hardest natural materials on this planet and they are virtually unbreakable.

While it is true that they are the hardest materials, it is equally true that they are extremely brittle and can be damaged very easily.

Follow these tips and prolong the life of your diamond cutting tools:

• Air bearing spindles tend to “roll” while in their stationary position. If the diamond is in contact during “roll”, the cutting edge will be damaged.
• The spindle must be locked to prevent “roll” during scribe testing.
• Use materials such as “Plasticine” or “Blue Tack”, or a similar clay-based product to stop “roll”.
• Never hand hold the spindle. Manually held spindles are insecure and the slightest “roll” will damage the tool.
• Never remove the tool from its container until you are ready to use it.
• Hold the cutting tool by the shank, never touch the diamond when cleaning it.
• Always apply the diamond to the part when rotating in the cutting direction only.
• Clean diamonds only with a fast drying solvent with a dampened tissue around the cutting edge. Never use a cotton bud.
• Change tools before too much wear takes place to prolong the overall tool life.
