The range of diamond grinding bits are 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), which gives them a high resistance to friction and temperature, which is why 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 includes cylindrical and conical models, 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.
