Kyocera THN07812 Indexable High-feed End Mill 3/4 in

Product Description

The KYOCERA THN07812 is an indexable high-feed end mill designed for aggressive metal removal in CNC machining applications. Built around the MFH toolholder platform, it accepts 3 LOGU 030310ER-GM inserts secured by screw clamping. The cutting diameter is 0.75 inches with a matching cylindrical shank diameter of 0.75 inches. Maximum depth of cut is 0.039 inches per pass, optimized for high-feed, low-engagement strategies that maximize material removal rates while reducing cutting forces on the spindle. Overall length is 6.5 inches with a head length of 3.0 inches. Through-coolant capability keeps the cutting zone clear and extends insert life during extended runs.

This end mill is suited for use on CNC machining centers in production and job-shop environments. It handles facing, shouldering, slotting, ramping, and plunging operations, making it a versatile choice for steel, cast iron, and other ferrous materials. The maximum ramping angle of 1.20 degrees keeps lateral loads controlled during ramp entry moves. Maximum spindle speed is 15,700 RPM. It is typically set up and operated by machinists, tooling engineers, and CNC programmers working in industrial manufacturing settings.

Key Features

• Indexable design with 3 LOGU 030310ER-GM inserts for fast, low-cost edge changes without regrinding
• Through-coolant delivery for improved chip evacuation and insert life
• MFH toolholder style with cylindrical shank for rigid, concentric mounting
• Supports facing, plunging, ramping, shouldering, and slotting operations in a single tool
• Maximum RPM of 15,700 supports high-feed strategies on modern CNC machining centers
• Maximum ramping angle of 1.20 degrees for controlled helical and ramp-entry moves

Compatibility

Compatible with LOGU 030310ER-GM inserts. Designed for use in the MFH high-feed milling system with a 0.75-inch cylindrical shank mount. Minimum cutting diameter is 0.435 inches and maximum cutting diameter is 0.75 inches.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on CNC milling equipment. Ensure the machine spindle and toolholder are clean and free of chips before seating the shank. Confirm insert seating and screw torque per the insert manufacturer guidelines before running the tool. Verify spindle speed and feed rate programming are within the rated parameters before initiating a cut.
