Accupro 314872 Square End Mill 1/2 in 3 Flute Carbide Zrn

Product Description

The ACCUPRO 314872 is a solid carbide square end mill designed for precision milling operations in metal-cutting and machining environments. Built from micrograin carbide and coated with zirconium nitride (ZrN), this end mill delivers extended tool life and improved surface finish in ferrous and non-ferrous materials. It features a 1/2 inch cutting diameter, a 2 inch length of cut, and a 37-degree helix angle that promotes efficient chip evacuation and reduced cutting forces. This is a single-end, center-cutting tool suited for slotting, profiling, and plunge milling. Machinists and tool-room professionals rely on this geometry for stable, accurate cuts in production and job-shop settings.

This end mill is well-suited for use in CNC machining centers and manual mills where right-hand cutting and right-hand flute spiral geometry are required. The 3-flute configuration balances chip clearance with rigidity, making it effective in both roughing and finishing passes on aluminum, steel, and similar materials. The 1/2 inch shank diameter matches standard ER and end mill holders commonly found in production shops. At 4 inches overall length with no extended reach designation, it fits standard tooling envelopes without requiring specialty holders.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN (zirconium nitride) coating for improved tool life and heat resistance
• 37-degree helix angle for efficient chip evacuation and smooth cutting action
• Center-cutting design allows direct plunge entry into workpiece
• Right-hand cut, right-hand spiral flute direction for standard CNC spindle compatibility
• Mill diameter tolerance of +0.000 / -0.005 inches for controlled sizing

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 1/2 inch end mill holders and ER collet chucks used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the holder and torque the retention mechanism to the holder manufacturer's specification. Verify runout with a dial indicator after installation before beginning any cut.
