Dymaxion Diamond Core Drill Turbo for Brick 65mm x 160mm CBTB65-160

Features:

• Diamond Turbo Core Bits are designed for coring holes in brick without the use of water.
• The range includes diameters that are popular with plumber's, electrician's and air conditioning installers.
• There is great variation in brick hardness and density - do not use excessive force or the core bit will overheat.
• To achive optimum cutting performance and maximum core drill life use a slow drill speed and low drill pressure.
• 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.
• DO NOT USE HAMMER ACTION.
