Harvey Tool 836390 Square End Mill 0.09 in 3 Flute Carbide

Product Description

The HARVEY TOOL 836390 is a solid carbide square end mill designed for precision milling in metal, composites, and other hard materials. It features a 0.09 inch cutting diameter with three flutes and a 30-degree helix angle, making it well suited for light-to-moderate material removal with good chip evacuation. The 17/64 inch length of cut and 1/8 inch shank diameter keep the tool compact and rigid. This is a single-end, center-cutting tool with a bright/uncoated finish, intended for use in CNC machining centers and manual mills. It is typically installed and operated by machinists and tooling specialists working in precision manufacturing environments.

This end mill is used in applications requiring tight-tolerance profiling, slotting, and contouring in small-bore or confined geometries. The 0.09 inch diameter makes it particularly useful for fine detail work, thin-wall features, and intricate cavity milling where larger tooling cannot reach. The right-hand cutting and right-hand flute direction are standard for conventional CNC setups. The 1-1/2 inch overall length provides adequate reach while maintaining stiffness to minimize deflection during cutting passes.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 3-flute geometry balances chip clearance with cutting surface contact
• 30-degree helix angle promotes smooth cutting action and chip evacuation
• Center-cutting design allows plunge entry into workpiece
• Bright/uncoated finish suitable for a wide range of general milling applications
• Compact 0.09 inch diameter for fine detail and small-feature work

Compatibility

Designed for use in CNC machining centers and manual milling machines with standard 1/8 inch collet or tool holder systems. Suitable for general-purpose square-shoulder milling, slotting, and profiling operations across a range of workpiece materials.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before loading or changing tooling. Secure the 1/8 inch shank fully within the collet or tool holder to the appropriate grip length before tightening. At small diameters, feed rate and depth of cut should be set conservatively to avoid tool breakage, particularly in harder workpiece materials.
