Kennametal 3870469 Square End Mill 3 Flute Solid Carbide

Product Description

The KENNAMETAL 3870469 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. Built with three flutes and a right-hand cutting direction, it delivers efficient chip evacuation and a clean square shoulder profile. The 0.375-inch shank diameter and single-end configuration make it a standard fit for CNC machining centers and manual mills alike. Manufactured to the K600 material grade specification, this end mill is supplied in a bright, uncoated finish — suitable for applications where coating-induced dimensional buildup is a concern or where the base carbide substrate performs best without an additional layer.

This end mill is suited for general-purpose milling, slotting, and profiling tasks in machine shops, production environments, and toolrooms. The center-cutting capability allows direct plunge entry into a workpiece, giving machinists flexibility for both plunge and ramping operations. The fixed helix geometry and standard index configuration provide predictable cutting performance across a range of milling applications. It is typically installed and used by CNC machinists, tool-and-die makers, and production machinists working in light to medium-duty cutting conditions.

Key Features

• Three-flute solid carbide construction for rigidity and wear resistance
• 0.375-inch shank diameter for compatibility with standard toolholders
• Center-cutting design allows direct plunge entry into workpiece material
• Right-hand flute direction and right-hand cutting for standard spindle rotation
• Bright, uncoated finish — K600 material grade solid carbide substrate
• Single-end configuration for straightforward toolholder mounting

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers, knee mills, and manual milling machines equipped with toolholders accepting a 0.375-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with end mill toolholder torque procedures and runout verification. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing end mills. Seat the shank fully into the toolholder collet or end mill holder before tightening to manufacturer specifications. Verify runout with a dial indicator before beginning cutting operations to avoid premature tool wear or workpiece damage.
