Accupro 313414 Square End Mill 5/8 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 313414 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. It features a 5/8 inch cutting diameter with a 4 inch length of cut, giving it extended reach capability for deep-pocket and side-milling work. The two-flute spiral design with a 45-degree helix angle promotes aggressive chip evacuation while maintaining surface finish quality. A ZrN (zirconium nitride) coating reduces friction and extends tool life when cutting ferrous and non-ferrous materials. The micrograin carbide substrate adds toughness and wear resistance. Licensed machinists and CNC operators are the primary users of this tool.

This end mill suits CNC machining centers and manual milling machines used in production shops, toolrooms, and job shops. The centercutting geometry allows the tool to plunge directly into a workpiece, enabling slotting, profiling, and pocket milling without a pre-drilled entry hole. The right-hand cut and right-hand flute configuration fits standard spindle rotation on conventional vertical and horizontal milling setups. With an 8 inch overall length, it handles applications where standard-length tools cannot reach the full depth of the feature being machined.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• ZrN coating reduces friction and extends cutting tool life
• 45-degree helix angle improves chip flow in deep cuts
• Centercutting design allows direct plunge entry without pre-drilling
• 2-flute spiral configuration suits slotting and pocket milling
• Right-hand cut and right-hand flute for standard spindle use

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 5/8 inch collet or end mill holders on CNC and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the shank in a compatible 5/8 inch collet, end mill holder, or shrink-fit holder and verify runout before cutting. Confirm that spindle speed and feed rate are set per the material being machined before engaging the workpiece. Inspect the tool for chipping or wear at regular intervals, as carbide tools can fracture if feed rates exceed the tool geometry limits.
