Kennametal 3854761 Square End Mill 5/8 in 3 Flute Carbide

Product Description

The KENNAMETAL 3854761 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 0.625 inch mill diameter, a 1.25 inch length of cut, and a 3-flute spiral geometry, this tool delivers efficient chip evacuation and a clean square shoulder profile. The 37-degree helix angle promotes smooth cutting action and reduced vibration during full-depth passes. Manufactured to Kennametal material grade K600 micrograin carbide, the uncoated bright finish makes this end mill well suited for applications where coating compatibility or regrinding is a priority. It is a single-end, center-cutting design, capable of plunging and peripheral milling. Machinists and tool-and-die professionals working in job shops, production environments, or maintenance settings will find this part a direct fit for standard Series AADE applications.

This end mill is used in milling ferrous and non-ferrous materials where tight tolerances and consistent tool geometry are required. The right-hand cut and right-hand flute configuration is standard for conventional CNC machining center spindles and manual knee mills. The 0.625 inch shank diameter fits directly into ER collets, end mill holders, and shrink-fit tooling sized for 5/8 inch shanks. The 3.5 inch overall length provides adequate reach for most standard workpiece setups without excessive overhang. No extended reach configuration is present, keeping deflection minimal at this diameter. Centercutting capability allows direct plunge entry into the workpiece without a pre-drilled pilot hole.

Key Features

• Solid micrograin carbide construction at material grade K600 for wear resistance and edge retention
• 37-degree helix angle promotes smooth chip flow and reduced cutting forces
• Center-cutting design allows direct plunge milling without a pilot hole
• Uncoated bright finish suitable for regrinding or use in applications where coatings are undesirable
• Right-hand cut and right-hand flute for compatibility with standard CNC and manual mill spindles
• Mill diameter tolerance of +0.000 / -0.002 inches and shank diameter tolerance of +0.00000 / -0.00043 inches for precise holder fit

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill in Kennametal Series AADE tooling programs. Fits standard 5/8 inch end mill holders, ER collets, and shrink-fit toolholders sized for a 0.625 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's torque and runout specifications. Ensure the spindle and toolholder are clean and free of chips before seating the shank to maintain concentricity and prevent premature tool wear. Always confirm spindle direction matches the right-hand cut orientation of this tool before engaging the workpiece. Follow all applicable machine guarding and PPE requirements per shop safety standards when handling and installing carbide cutting tools.
