Kennametal 6113105 Ball End Mill 6 Flute 1/2 in Solid Carbide

Product Description

The KENNAMETAL 6113105 is a 6-flute, single-end ball end mill from the HARVI III UJBE series, engineered for high-performance material removal in demanding machining environments. Built from solid carbide and coated with AlTiN via a PVD process, it delivers heat resistance and wear life in applications where tool temperature and edge stability are critical. The mill measures 0.5 inches in diameter with a 1.5-inch length of cut, a 0.5-inch straight cylindrical shank, and a 3.5-inch overall length. A 38-degree medium helix angle and variable index flute spacing work together to suppress chatter during both roughing and finishing passes. Material grade KCSM15 makes this tool well suited for ferrous and superalloy work.

This end mill is designed for machining steel, stainless steel, high-temperature alloys, and hardened materials, corresponding to workpiece material codes P, M, S, and H. It is centercutting with right-hand cutting and right-hand flute direction, making it compatible with standard vertical and horizontal milling centers. The HARVI III Aero series addresses a broad range of operations, from slotting and profiling to semi-finish and finish ball-end contouring. No extended reach or coolant-through capability is included, so this tool is best applied in setups where flood or mist coolant is delivered externally. Licensed machinists and CNC programmers in aerospace, die and mold, and general precision machining shops are the primary users.

Key Features

• Solid carbide construction in material grade KCSM15 for rigidity and wear resistance in difficult alloys
• AlTiN PVD coating provides high-temperature oxidation resistance for dry or semi-dry cutting
• Variable index flute spacing reduces chatter during aggressive roughing and finishing operations
• 38-degree medium helix angle balances cutting force and chip evacuation in deep pockets
• Centercutting geometry enables direct plunge entry and ball-end contouring without pre-drilling
• 0.25-inch nose radius (ball end) on a 0.5-inch diameter for accurate 3D surface contouring

Compatibility

Suited for use in machining steel, stainless steel, high-temperature alloys, and hardened materials (ISO material codes P, M, S, H). Part of the KENNAMETAL HARVI III UJBE series; catalog number UJBE0500J6ZB.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Confirm that the machine spindle and tool holder are clean and within specified runout tolerances before seating the 0.5-inch straight cylindrical shank. Power down and lock out the spindle before tool changes. Do not exceed the tool holder's rated clamping torque range, and verify cutting parameters against the KENNAMETAL HARVI III published feeds-and-speeds data for the specific workpiece material before running the program.
