The 2-hole design on the carbide rod allows for increased coolant flow and better chip evacuation compared to a single-hole design. This helps to improve tool life and cutting performance, especially in high-speed machining operations where heat and chip buildup can be a problem, widely used in drills, reamers, carbide holders. We supply both unground and ground carbide rods with two cooling holes in varied grades.
