Rockstar Core Bits
Stone core bits are aggressive and long-lasting. The soft bonded segments are made for the hardest granites and will core holes in seconds, not minutes. Vacuum brazed diamonds are on the outside of the barrel of our 1” – 2” bits to prevent the bit from locking up. Additional vacuum brazed diamonds on the inside of these bits allow for easy plug removal. Arbor is 5/8 – 11 to fit all grinders and polishers.
