Diamond Core Drill Bits are used to drill in floor tile, wall tile glass, stone tile, limestone, sandstone, slate, marble and thin granite.

In addition to the tile drill bits, we also carry many other diamond tools for use primarily on sandstone, marble, limestone, granite, stone and more.  There are basically two styles of diamond drill bits - core style and blunt nose solid tip bits.  The blunt nose type clears out the complete hole, while the core type works like a hole saw and cuts only a circle to creat the hole and leaving a "plug".  A core style diamond drill bit is often called a hole saw since is saws a circle to create the hole.  The blunt nose type is more suited for glass and curved surfaces (since it is easier to start), while the core type works on stone in addition to glass.  All diamond drill bits are manufactured in two different types - electroplated and sintered.  Electrolplated have diamonds bonded to the tip of the bit while the sintered type has them embeded into the steel tip during the fabrication molding process.  Orders ship out with in 24 hours and orders received by 1:00 pm cst normally ship out that afternoon.
