Kyocera THN07720 Indexable High-feed End Mill 5/8 in

Product Description

The KYOCERA THN07720 is a 2-flute indexable high-feed end mill designed for aggressive metal removal in CNC milling operations. It features a 5/8 inch (0.6250 inch) cutting diameter, a Weldon flat shank of equal diameter, and an overall length of 3.196 inches. The toolholder style is MFH and the body accepts two LOGU 030310ER-GM inserts secured by screw clamping. Through-coolant capability supports extended tool life and chip evacuation at high spindle speeds up to 18,800 RPM. This tool is appropriate for machinists and CNC operators working in production or job-shop environments on steel, cast iron, and similar workpiece materials.

The THN07720 is suited for a range of milling operations including facing, shouldering, slotting, plunging, and ramping. Its maximum ramping angle of 0.80 degrees and a maximum depth of cut of 0.039 inches (0.99 mm) per pass are consistent with high-feed milling strategy, where shallow axial depth is traded for high feed rates to maximize material removal rate while reducing cutting forces. It is intended for use in machining centers where a Weldon flat retention system is available.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or changing the tool or inserts. Confirm Weldon flat set screw engagement and torque per your toolholder manufacturer specification before running. Verify coolant-through passages are clear and flow is confirmed before beginning the cut cycle.
