Electroplated Diamond Core Drill

Electroplated Diamond Drill Bits for Glass, Ceramic, Porcelain, Tile & Stone are made by diamond coating one end of a metal base. Use these diamond core drill bits to make holes in a variety of hard to cut materials. Unlike conventional twist drills, diamond drills work by gently grinding (or sanding) the material you are cutting. This process takes time, you have to be patient. A core drill will cut more quickly than a solid drill since it is only cutting out a small circle of material. The larger size core drill bits will also give you a useable core, but the core from the smaller drill bits are usually destroyed during the cutting process. These tools work on all types of stone,glass,tile,composites,plastics,resins,porcelain,eggs,and much more. The smaller sizes can be used in a hand drill or rotary tool (like a Dremel or Foredom), but the larger sizes should be used in a drill press.

Metal Bonded Diamond Core Drill

Sintered Diamond Core Drills made with our exclusive metal bond developed for high strength and longevity,metal bond diamond core drills are the finest core drills manufactured in the world. Diamonds held in a metal matrix bond for core drilling glass, alumina quartz, ruby yag, silicon and other hard abrasive non-metallic ceramics.Sintered diamond drill bits are heavy-duty bits designed for long life. Generally, sintered bits will have a long life of 20 to 30 or more times the life of a bonded diamond drill bit, if used properly. The heavy-duty design provides long life when drilling in very hard materials such as porcelain tile, granite and hard stones. However, there are some disadvantages. Sintered bits are much more expensive than bonded diamond bits and the thick heavy-duty tip causes them to drill more slowly than thin-wall bonded diamond drill bits.
