Decrease cutting speed 30% 40% contrast with recommended condition when machining forged steel 2. Decrease cutting condition considering the overhang of drill, machined rigidity, precision of spindle, clamping and surface of workpiece, etc. 3. For longer tool life, Please apply to step feed at every 1.5D 4. Put the drill clamping between edge groove and shank boundary part in order to be located in the suitable position 5. Coolant pressure for through hole type = 3 5kg/cm3, volume = 2 5l/min 6. Cutting formula Mach Drills Through coolant type MSD(H) -dN) cemented carbide Tool Dia.

In case of using further cutting speed or feed rate than recommended conditions to improve the productivity, please apply it after enough tests because it could be occurred some problems like early wear, built-up edge, chipping, fracture, etc. G Drills 54
