Accupro 314450 Square End Mill 1/8 in 3 Flute Carbide Zrn

Product Description

The ACCUPRO 314450 is a single-end, three-flute square end mill designed for precision milling in a wide range of metalworking and machining applications. Built from micrograin solid carbide and finished with a ZrN (zirconium nitride) coating, this end mill delivers high wear resistance and extended tool life compared to uncoated alternatives. It features a 1/8 inch cutting diameter, a 3/8 inch length of cut, and a 37-degree right-hand helix angle that promotes efficient chip evacuation. Licensed machinists and CNC operators use this tool for slotting, profiling, and peripheral milling in production and job-shop environments.

This end mill is suited for use in CNC machining centers, knee mills, and benchtop milling machines where a 1/8 inch shank is required. The 1-1/2 inch overall length and compact geometry make it appropriate for close-tolerance work in ferrous and non-ferrous materials. The ZrN coating provides lubricity that benefits dry or minimal-lubrication cutting strategies. It is a solid choice for shops machining steel, aluminum, brass, and similar materials where tool rigidity and surface finish quality are priorities.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• ZrN coating improves lubricity and extends tool life in dry-cutting conditions
• 37-degree right-hand helix promotes efficient chip evacuation and reduces heat buildup
• Center-cutting geometry allows plunge entry as well as peripheral and slot milling
• Right-hand cutting direction compatible with standard CNC spindle configurations
• Spiral flute type with no chipbreaker for smooth surface finish on finish passes

Compatibility

Designed for use in milling machines and machining centers that accept a 1/8 inch shank diameter. Suitable for tool holders, collets, and chucks sized for 1/8 inch straight-shank tooling.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully powered down and locked out. Seat the shank fully into the collet or tool holder and torque the retention system per the holder manufacturer specification. Inspect the cutting edges for chips or damage before each use. Verify spindle speed and feed rate are appropriate for the workpiece material before engaging the cut.
