ViperĀ® Core Bits for Stone

Do you need to drill small holes in porcelain, glass or granite tile?  Look no further.  Raimondi ProBits are the best drill bits that we have found for these materials.

Wet or Dry?  Dry core bits are designed to operate at higher RPM's than wet core bits. All dry core bits sold by Braxton-Bragg can be used wet by simply reducing the RPM. 

To get the best performance and longevity, read and follow the manufacturer's RPM recommendations.

Guaranteed Quality – All of our products carry a 30-day, risk-free, money-back guarantee. If you are not satisfied with your purchase, simply return it for a prompt and courteous refund.
