Rubi Diamond Drill Bits For Grinding

RUBI Tools’ range of diamond grinding bits is a must-have for professionals looking to modify, enlarge, or fine-tune the diameter and shape of previously drilled holes. These versatile bits aren’t designed for drilling but excel at smoothing, polishing, and cleaning the inner edges of holes, especially in landscaping materials. Engineered with vacuum brazing technology, the diamond particles are firmly bonded to the bit’s body, giving them exceptional resistance to friction and heat—ideal for dry working conditions. Operating efficiently at speeds from 6,000 to 11,000 rpm, these bits feature a universal M14 threaded connection compatible with most grinders on the market. With a coarse #50/60 diamond particle size, they ensure powerful, effective material removal.

The diamond grinding bits come in both cylindrical and conical SUPERPRO models, available in a variety of sizes to meet the diverse needs of professionals. The cylindrical bits are designed with strategically placed holes to enhance cooling during extended use, helping to extend tool life and maintain performance. With a high concentration of industrial-grade diamonds, these bits promise long-lasting durability and consistent results. As part of RUBI’s renowned diamond tool family, each bit undergoes rigorous testing to meet the brand’s exceptional standards. This dedication to quality and reliability has earned RUBI a trusted reputation among construction and tile installation experts worldwide. For optimal safety, the use of personal protective equipment is strongly recommended during operation.
