125-153 3.15 ● Standard configuration includes 1 set (1 piece on each side) cartridge, through the special design of tool body and interchangeable cartridge positions (refer to the corresponding letters in the top-right diagram), enables quick switching between single-edge axial step boring and twin-edge boring operations. ● Each model is equipped with a set of tool holder lock screws and one L-shaped wrench; the insert need to be ordered separately. ● The ARS step boring series is equipped with internal coolant. ● Before use, ensure that the tool is securely clamped and there are no gaps between the mating surfaces. It is recommended to verify this using a feeler gauge or the light transmission method. ● When using the ARS step boring tools, radial adjustments can be made to effectively reduce issues such as bad chips and vibration during more material cutting.
