CYLINDRICAL BIT DIAMOND SUPERPRO Ø 20

RUBI Diamond Core Drill 06985. The range of diamond core drills is specifically designed for enlarging or modifying the diameter and shape of previously drilled holes. They can also be used for smoothing, polishing, or cleaning the internal edges of holes. Diamond core drills are effective when working with materials used in landscape architecture. Core drills are NOT suitable for drilling holes. Diamond particles are attached to the body using a vacuum soldering technique, which ensures high resistance to friction and temperature. As a result, the core drills are intended for dry work. The diamond particles in our core drills are sized #50/60. The M14 threaded connection allows for use with grinders, with a recommended speed of 6000 to 11000 rpm. The range of core drills includes models with cylindrical and conical shapes, in various sizes and classified as SUPERPRO quality.
