Accupro 314900 Square End Mill 1/2 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 314900 is a single-end, three-flute square end mill designed for high-performance milling in a wide range of metalworking and machining applications. Constructed from micrograin solid carbide and finished with a ZrN (zirconium nitride) coating, this tool delivers hardness and wear resistance suited to demanding cutting environments. The 1/2 inch cutting diameter pairs with a 4 inch length of cut, making it capable of handling deep-cavity and extended-reach profiling work. A 37-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Licensed machinists and CNC programmers in job shops and production environments are the primary users of this tooling.

This end mill is appropriate for milling operations on ferrous and non-ferrous materials where a long length of cut is required. The right-hand cut and right-hand spiral flute direction are standard for conventional CNC machining center setups. At 8 inches overall length with a 1/2 inch shank diameter, it fits standard collet and end mill holder tooling systems. Its centercutting capability allows plunge entry as well as peripheral and slot milling operations.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• ZrN coating improves wear resistance and reduces friction at the cutting edge
• 37-degree helix angle promotes efficient chip evacuation in deep cuts
• 4 inch length of cut supports deep-cavity and long-reach milling
• Centercutting design permits direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute direction for standard CNC setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills using 1/2 inch collets or end mill holders with a 1/2 inch bore.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank in a properly sized collet or end mill holder to the torque specification recommended by the holder manufacturer. Verify runout with a dial indicator before initiating a cut to protect edge integrity and workpiece accuracy.
