A boring head assembly from Sandvik Coromant, part number 391.26-40 80 120, from the Varilock modular tooling system. The unit consists of a CAT40 taper shank coupled to a Varilock 40 interface, which in turn connects to the 80 mm diameter boring head body. The part number stamped on the Varilock coupling reads 391.26-40 80 120, with an additional casting code visible on the shank section reading A390 43-50 63. The boring head features a large-bore front face with visible insert pockets configured for face milling or large-diameter boring operations, and a threaded coolant port is visible on the side of the body. The CAT40 taper includes the standard retention knob thread and orientation keyway slots. Sandvik Coromant Varilock tooling is a modular system widely used in CNC machining centers, allowing interchangeable combinations of shanks, extensions, and cutting units. This assembly is compatible with CAT40 spindles and accepts Varilock 40 interface tooling components. The 120 designation in the part number corresponds to the maximum boring diameter range in millimeters.
