Sintered Diamond Core Drill Bits for Marble/Granite/Ceramic/Tile/Concrete
Sintered diamond bits have the diamonds embedded directly into the metal tip of the bit. As the tip wears down, new diamonds come to the surface. Sintered diamond drill bits are often designed for drilling in stone, concrete or masonry. Sintered diamond drills are heavy duty, the drilling speed is slower than Electroplated Diamond Hole Saw, but they last longer. Depending upon the material being drilled and the drilling techniques used, Sintered diamond bits can last 30 to 50 times longer than a electroplated diamond bit, sometimes even longer.

The cutting speed and life of a diamond drill bit are affected by the hardness and abrasiveness of the material plus the drill speed, pressure and lubrication. Even the drill bits designed for dry drilling, using lubrication will extend the bits life considerably.
