Description
About this item:
- 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 than 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.
- SPEEDS IN RPM: Fibreglass - 1200, Glass, Ceramic and China - 800, Limestone and Marble - 600, Ceramic Tile - 600, Porcelain - 500, Granite and Comp. Stone - 400.
