Diamond Core Drill For Granite Porcelain and Polymer Concrete 48mm Dia

About this item:

• Can be used for coring polymer concrete and plastic/glass cable joining pits. Avoid overheating by quenching in water.
• Suitable for cutting hard porcelain and granite bench tops. Ensure plenty of water to cool and remove waste from the cut.
• 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.
• 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.
