Accupro 313366 Square End Mill 5/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313366 is a solid carbide square end mill designed for precision material removal in milling operations. It features a 5/8 inch cutting diameter, a 1-1/4 inch length of cut, and a 45-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate delivers the hardness and wear resistance needed for demanding cuts in ferrous and non-ferrous materials. With a bright/uncoated finish, this end mill is well suited for applications where base carbide performance is preferred over coated variants. It is sold as a single-end tool and weighs approximately 1.05 pounds.

This end mill fits standard milling machine setups including CNC machining centers and manual knee mills. It is commonly used in job shops, maintenance machining, and production environments where precise slotting, profiling, and peripheral milling are required. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. The regular length designation suits general-purpose work where extended reach is not needed. Machinists and tool-and-die professionals are the primary users of this style of tooling.

Key Features

• Solid carbide micrograin construction for hardness and edge retention
• 45-degree helix angle promotes efficient chip flow and reduced cutting forces
• 2-flute design suited for slotting and pocketing operations
• Center-cutting capability allows plunge entry into workpieces
• Right-hand cut and right-hand spiral for standard spindle use
• Bright/uncoated finish suitable for general-purpose milling applications

Compatibility

Designed as a general-purpose square end mill for use in standard milling machine spindles and CNC machining centers accepting a 5/8 inch shank diameter tool holder.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Confirm runout and tool projection meet the requirements of the operation before engaging the workpiece. Follow shop safety protocols and machine manufacturer guidelines for tool clamping torque and RPM limits.
