- POLISTAR flexible tools have been especially developed for work on the inner surfaces of holes and pipes. - Advantages: - Optimum adaptation to contours thanks to high flexibility. - Most effective work on small inner diameters, particularly in the range of 7–40 mm, due to tool dimensions.
- The Innovative Full Head Carbide drill bit offers the highest levels of performance to users with the hardest applications. - Superior carbide grade and geometry ensures greater resistance to breakage and premature wear to ensure maximum drill bit life and durability. - Four cutter geometry delivers maximum hole concentricity for better fixing retention.
