Dressing Sticks 

Sintered (Metal Bond) Diamond Drills should be periodically dressed, in order to rexpose new diamonds. Otherwise, the diamond tool will glaze over. They will begin to tear rather than grind which is very destructive. Tearing caused from unexposed diamonds creates friction. This causes uneven wear and heat cracks in the diamond tool as well as material being drilled. Resulting in premature diamond tool wear, blade tensioning problems, and will eventually destroy the diamond tool. The more a diamond drill is dress the faster and more consistently it will drill.    more >>>
