Kennametal 5058618 Square End Mill 1/4 in 2 Flute Carbide

Product Description

The KENNAMETAL 5058618 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. Built to AADF series specifications, this centercutting tool features a 45-degree helix angle and a 2-flute spiral configuration that promotes efficient chip evacuation and smooth cutting performance. With a 0.25-inch mill diameter, 1.125-inch length of cut, and 3-inch overall length, it is sized for tight-tolerance work in both ferrous and non-ferrous materials. The micrograin carbide construction delivers hardness and edge retention across demanding cutting conditions. Machinists and CNC programmers in job shops and production environments rely on this tool for accurate square-shoulder and slot milling passes.

This end mill suits general-purpose milling applications where a compact 1/4-inch diameter tool is required. The long-length configuration and uncoated bright finish make it well suited for applications where coating compatibility is a concern or where regrinding is part of the tool management program. Right-hand cut and right-hand flute geometry follows standard milling conventions, making it a direct fit for conventional CNC machining centers and manual knee mills operating with standard spindle rotation.

Key Features

• Solid micrograin carbide construction for superior hardness and wear resistance
• 45-degree helix angle promotes smooth chip flow and reduced cutting forces
• Centercutting design allows plunge entry into workpiece material
• 2-flute spiral geometry suits slotting and profiling in a range of materials
• Uncoated bright finish compatible with a wide range of cutting fluids and regrind programs
• Right-hand cut and right-hand flute orientation for use with standard CNC and manual mills

Compatibility

Designed as an OEM-style solid carbide square end mill replacement suitable for standard 1/4-inch collet or end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before securing the end mill. Use a properly sized collet or end mill holder rated for 1/4-inch shank diameter and torque the retention system per the tool holder manufacturer specifications. Confirm correct runout with a dial indicator before beginning cutting operations.
