RUBI Diamond Drill Bits for Grinding (Chamfer bits)

The range of diamond grinding bits is specially designed to enlarge or modify the diameter and shape of a previously drilled hole. They can also be used for smoothing, polishing, or cleaning the inside edges of previously drilled holes.

Diamond grinding bits are suitable for landscaping materials. Diamond grinding bits are NOT suitable for drilling holes.

The attachment of the diamond particles to the body of the bit is carried out using the vacuum brazing technique (vacuum brazed). This gives them a high resistance to friction and temperature, so they are drills for working in dry conditions. The diamond particles used in the grinding bits have a particle size of #50/60.

Thanks to their M14 threaded connection, they can be used with any grinder on the market at rotational speeds between 6,000 and 11,000 rpm.

The range of diamond grinding bits offered by RUBI Tools includes cylindrical and conical models now, in different sizes to adapt to the needs of the professional, and have been classified as SUPERPRO.

Due to its high concentration of diamond, it gives the drill a long life and stable performance.

In addition, the body of the cylindrical drill bit models has been provided with holes that help improve the drill bit's cooling during grinding work. As with the rest of the products in the diamond family, RUBI recommends always using the necessary personal protection equipment for the use of diamond drill bits for grinding.

Problem

Professionals working with landscaping and construction materials often need to grind or shape hard surfaces such as natural stone, ceramics, and concrete. However, standard grinding tools may overheat, wear out quickly, or lack the precision and durability required for consistent performance. Additionally, using the wrong tool (such as drill bits designed for hole-making) can result in inefficient work, damaged materials, or unsafe conditions. 

Solution

The RUBI Diamond Drill Bit for Grinding is specially engineered for dry grinding of landscaping and construction materials—not for drilling holes. By using vacuum brazed diamond particles (#50/60 grit), the bit offers exceptional resistance to friction and heat, ensuring long-lasting, stable performance even in high-speed grinding applications (6,000–11,000 rpm). Its M14 threaded connection fits all standard grinders, and its cylindrical and conical SUPERPRO models provide versatility for different grinding needs. Integrated cooling holes in cylindrical models further enhance tool longevity and performance, making it a reliable choice for professionals seeking quality, durability, and efficiency on the job site.
