FEATURES:

• Diamond Hole Saws
• Diamond core drills and hole saws require the use of proper lubrication, correct drill speed and proper pressure.
• Drilling methods and techniques vary significantly depending upon the material being drilled
• To achive optimum cutting performance and maximum core drill life use a slow to very slow drill speed, low drill pressure, and plenty of water for lubrication. Variable speed drills work best since the correct speed can be selected.
• Diamond core drills only drill out a portion of the resulting hole so they drill much faster then conventional blunt nose drills. Core drills can be used on most non-ferrous hard materials such as glass, ceramic, porcelain, fibreglass, slate, marble, granite and other natural and manufactured stone materials.
• The life of any type of diamond drill depends upon the hardness, abrasiveness and thickness of the material being drilled and the specific drilling techniques used.
• Using diamond core drills in hard materials is not difficult, however drilling the hole takes time. You should consider that they aren't "drilling" a hole — they are "grinding" a hole.
