Kennametal 3658836 Square End Mill 1/2 in 3 Flute Carbide

Product Description

The KENNAMETAL 3658836 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 1/2 inch cutting diameter, a 2 inch length of cut (LOC), and a 1/2 inch shank diameter with a 4 inch overall length (OAL). The 3-flute, right-hand spiral configuration runs at a 37-degree helix angle, balancing chip evacuation with surface finish quality. Manufactured from Kennametal K600 micrograin carbide, this single-end, centercutting tool is supplied in an uncoated (bright) finish. It is installed and run by machinists and CNC operators in job shop and production environments.

This end mill is suited for slotting, peripheral milling, and plunge operations on a wide range of workpiece materials. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. The AADE series designation indicates a standard-geometry, general-purpose profile appropriate for use in vertical machining centers, knee mills, and CNC milling machines across light to medium-duty cutting applications. Right-hand flute direction is compatible with conventional right-hand spindle rotation.

Key Features

• Solid K600 micrograin carbide construction for wear resistance and edge retention
• 3-flute, right-hand spiral design at 37-degree helix for efficient chip evacuation
• Centercutting geometry enables direct plunge milling without a pilot hole
• Uncoated bright finish suitable for a broad range of base materials
• Shank diameter tolerance of +0.00000 / -0.00043 inches for consistent tool holder fitment
• Mill diameter tolerance of +0.000 / -0.002 inches for dimensional accuracy

Compatibility

Designed as an OEM-style solid carbide end mill in the AADE series, compatible with standard 1/2 inch collets, end mill holders, and shrink-fit tool holders used in CNC vertical machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank to the full recommended engagement depth in the tool holder and verify runout with a dial indicator before beginning a cut. Follow the machine tool manufacturer guidelines and applicable shop safety procedures for speeds and feeds.
