Accupro 12178610 Square End Mill 5/8 Inch 3 Flute Carbide

Product Description

The ACCUPRO 12178610 is a solid carbide square end mill designed for precision milling operations in metal, composites, and other hard materials. With a 5/8-inch cutting diameter, a 1-1/4-inch length of cut, and a 3-1/2-inch overall length, this tool delivers consistent material removal in regular-length applications. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces during aggressive passes. Micrograin carbide construction provides the hardness and edge retention needed for demanding machining environments. Three flutes balance chip clearance with surface finish quality, making this cutter suitable for a range of milling strategies from slotting to peripheral profiling.

This end mill is intended for use in CNC machining centers and manual milling machines where a right-hand cut, right-hand flute configuration is standard. The centercutting geometry allows for direct plunge entry, eliminating the need for a pre-drilled start hole in most operations. The uncoated finish makes it a straightforward choice for general-purpose applications or for use with cutting fluids where coating adhesion is not required. Machinists and tooling specialists working in job shops, production machining, and maintenance repair operations will find this a reliable all-around cutter.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute orientation for standard CNC and manual mill setups
• Uncoated finish compatible with cutting oil and coolant applications
• Mill diameter tolerance of +0.000 / -0.002 inches for close-tolerance fitment

Compatibility

Designed as a standard shank end mill compatible with 5/8-inch collets, ER-style chucks, and end mill holders commonly used on CNC machining centers and manual knee mills. No specific model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully powered down and locked out before loading or removing the tool from the holder. Verify collet or chuck runout before engaging the cut, as excessive runout accelerates edge wear on carbide tooling. Follow the machine manufacturer and tooling guidelines for feed rate and spindle speed selection appropriate to the workpiece material.
