CUTTING HEAD WITH COOLANT CHANNEL

摘要

PURPOSE: A cutting head including a refrigerant channel is provided to lengthen service life of a cutting tool by supplying a refrigerant from a basic body to a cutting head through internal channels such as a central refrigerant channel. CONSTITUTION: A cutting head (100) including a refrigerant channel comprises a cutting unit (110), a coupling unit (130), and a refrigerant slot (150). The cutting unit includes a chip flute (114) and either a cutting blade or an insert sheet. The coupling unit is located to the rear of a cutting end of a cutting head in the axis direction of the cutting unit. The refrigerant slot is extended to the axis direction in the coupling unit and is opened on the outer radius periphery of the cutting head.
