Kennametal 3870466 Square End Mill 3/8 Inch Solid Carbide

Product Description

The KENNAMETAL 3870466 is a 3-flute, solid carbide square end mill designed for precision milling in metalworking and machining applications. Built on the KenCut series platform and manufactured from K600 grade carbide, this tool delivers consistent chip evacuation and tool life in ferrous and non-ferrous materials. The 3/8-inch mill diameter and matching 3/8-inch straight cylindrical shank make it compatible with standard collet and end mill holder systems. A 37-degree helical flute geometry promotes smooth cutting action and reduces cutting forces. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern.

This end mill is suited for slotting, profiling, and peripheral milling operations in job shops, tool rooms, and production machining environments. The center-cutting capability allows plunge entry without a pre-drilled pilot hole, giving machinists flexibility in toolpath programming. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC and manual milling setups. Regular length geometry keeps deflection low during aggressive lateral passes.

Key Features

• K600 solid carbide construction for wear resistance in demanding cuts
• 37-degree helical flute angle improves chip flow and surface finish
• Center-cutting design allows direct plunge entry
• 3/8-inch straight cylindrical shank fits standard collet chucks and end mill holders
• Bright, uncoated finish for compatibility with a wide range of workpiece materials
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as an OEM-style replacement and standard-stock cutting tool for use in 3/8-inch collet systems and end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth per the holder manufacturer guidelines. Inspect the cutting edges for chips or damage before each use and replace the tool if edge integrity is compromised.
