An effective method used for roughing out cavities is plunge drilling which uses repeated axial cuts to make a deeper hole or cavity. The Coromant U drill is ideal for use in broad machining conditions.

Demanding plunge drilling operations can be undertaken due to the high tool body strength. The Coromant U drill offers a power-efficient and productive solution with a high metal removal rate.

The Coromant U drill features a center and periphery insert, geometrics and grades for all materials and wiper geometry for the best surface finish. It can be supplied with internal coolant and an engineered special options diameter range is available.

It can be used for plunge drilling most materials with a maximum drill depth of 6 x DC for through- and blind holes. The latter must be monitored for the accumulation and evacuation of chips.
