Accupro 313350 Square End Mill 1/2 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 313350 is a solid carbide square end mill designed for precision material removal in milling operations. Built from micrograin carbide and coated with zirconium nitride (ZrN), it delivers extended tool life and reduced heat buildup in demanding cutting applications. The 2-flute, right-hand spiral geometry with a 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 6 inches overall length with a 3.25-inch length of cut, this is an extra-long configuration suited for deep-cavity and long-reach work. The 0.5-inch diameter and matching 0.5-inch shank diameter make it compatible with standard collet and end mill holder setups used by machinists and toolroom operators.

This end mill is suited for use in CNC vertical machining centers, manual mills, and toolroom equipment where extended reach into pockets, slots, or deep profile features is required. The single-end, centercutting design allows both plunge and peripheral milling. The ZrN coating provides a hard, low-friction surface that performs well on steels, cast iron, and non-ferrous alloys. Its extra-long length makes it appropriate for aerospace, mold and die, and general metalworking applications where standard-length tooling cannot reach the required depth.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN (zirconium nitride) coating reduces friction and extends tool life
• 45-degree helix angle promotes efficient chip evacuation
• Extra-long 6-inch OAL with 3.25-inch length of cut for deep-reach applications
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 1/2-inch collets, end mill holders, and hydraulic chucks used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended engagement depth in the holder and torque set screws per the holder manufacturer specification. Inspect the tool shank and flutes for chips or damage before each use, and verify runout with a dial indicator after installation.
