Product Features

● steel straight shank k-joint lengthening tool bar and solid carbide joint bar

● cemented carbide tool bar, the ratio of tool bar length to diameter (l/d) can reach 7 times, effectively prevent cutting vibration

● steel straight shank k-joint tool bar, the length-diameter ratio (L/D) of the tool bar can be up to 6 times

● use the Sonde module K interface

● adapt the coarse and fine boring head to realize the coarse and finish machining of the hole

● it is suggested to use the powerful tool shank or the hydraulic tool shank to clamp
