2 HELICAL COOLANT HOLES CARBIDE ROD

Carbide rods with helical coolant holes greatly avoid the early wear and failure of the tungsten carbide tools during high-speed machiningby the coolant in helical holes to reduce the temperature evenly, widely used in cutting and machining applications. The helix angle determines the efficiency of chip evacuation during the cutting process, which is critical for preventing tool wear and damage to the workpiece.We supply 30°& 40°helix,and unground & ground carbide rods with twohelical cooling holes in varied grades.

A comprehensive standard selection of carbide rods with helical cooling holes in various dimensions is available in the below tables, but other sizes, tolerances & configurations also available on request.
