Kennametal 6413216 Square End Mill 1/2in 6 Flute Carbide

Product Description

The KENNAMETAL 6413216 is a 6-flute solid carbide square end mill designed for high-performance milling in demanding metalworking applications. Built from KCPM15 carbide grade and coated with AlTiN, this tool handles elevated cutting temperatures and abrasive workpiece materials effectively. The 45-degree helix angle promotes smooth chip evacuation and reduces cutting forces across a range of materials. With a 1/2 inch cutting diameter and 2 inch length of cut, it suits deep-slotting, profiling, and finishing passes where rigidity and heat resistance are priorities. Licensed machinists and CNC operators in job shop and production environments will find this end mill suited to steel, stainless, and high-temp alloys.

This end mill is built for single-end use on vertical and horizontal machining centers as well as CNC milling machines. It fits standard 1/2 inch straight-bore tool holders, collet chucks, and hydraulic chucks. The extended reach configuration with a 2 inch reach length makes it well-suited for deep-pocket milling, cavity work, and contour operations where standard-reach tooling cannot access the feature geometry. It is a right-hand cut, right-hand flute tool.

Key Features

• 6-flute design increases feed rates and improves surface finish compared to 4-flute tooling in finishing cuts
• AlTiN coating provides oxidation resistance and hardness at elevated cutting temperatures
• 45-degree helix angle promotes efficient chip evacuation and reduced cutting pressure
• KCPM15 solid carbide grade delivers wear resistance in ferrous and high-temp alloy machining
• Extended reach of 2 inches allows access to deep pockets and cavity features
• Centercutting construction supports plunge entry without pre-drilled starting holes

Compatibility

Designed for use in standard 1/2 inch straight-bore tool holding systems including collet chucks, end mill holders, and hydraulic chucks on CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and machine is in an estop or locked-out state before changing tooling. Seat the shank to the full recommended engagement depth in the tool holder and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut to avoid premature tool wear or workpiece damage.
