A high pressure coolant tube for receipt by a tool body that includes a coolant tube body with an annular flange adjacent to the exit body end. There is a threaded collar that has an exterior threaded surface. The threaded collar contains an interior collar bore comprising an enlarged diameter interior collar bore surface portion and a reduced diameter interior collar bore surface portion. There is an exit seal pocket defined by an exit-facing flange surface of the annular flange and a reduced diameter body section and the enlarged diameter interior collar bore surface portion. There is an entrance seal assembly pocket defined by an entrance-facing flange surface of the annular flange and a reduced diameter body section and the enlarged diameter interior collar bore surface portion. An exit seal is in the exit seal pocket. An entrance seal assembly is in the entrance seal assembly pocket wherein the entrance seal assembly comprises an entrance seal sandwiched by a pair of thermoplastic polyester elastomeric rings.

The invention relates to a side milling cutter (1) which comprises a disk body (11) with a central hub (12) for accommodation in a milling drive, and a plurality of cutters (21) which are arranged on the outer periphery thereof. A plurality of inner cooling lubricant channels (3) extend in the disk body (11), said channels having two or more outlet openings (31) in the area of each cutter (21). Said outlet openings (31) are oriented such that a cooling lubricant jet (K) which exits from the cooling lubricant channel (3) can be directed to the cutter (21). The invention also relates to a production method for the side milling cutter (1).
