Accupro 313431 Square End Mill 3/4 in 2 Flute Carbide

Product Description

The ACCUPRO 313431 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 3/4-inch cutting diameter and a 1-1/2-inch length of cut, it handles slotting, profiling, and peripheral milling in a single-end configuration. The 45-degree helix angle promotes smooth chip evacuation and reduces cutting forces at the tool-workpiece interface. Manufactured from micrograin carbide, this end mill delivers consistent edge retention and dimensional stability in demanding cutting conditions. It is sold individually and is intended for use in CNC machining centers and manual mills by machinists and tool-and-die professionals.

This end mill suits general-purpose milling of ferrous and non-ferrous metals in job shop, production, and maintenance machining settings. The bright uncoated finish makes it well-suited for materials where coating adhesion or heat sensitivity would be a concern, such as aluminum and non-ferrous alloys, while still performing adequately in mild steel applications. The 3/4-inch shank diameter provides a secure, low-runout grip in standard collet chucks and end mill holders. The regular-length geometry keeps deflection manageable in typical depth-of-cut scenarios without extended reach.

Key Features

• 3/4-inch cutting diameter with a 1-1/2-inch length of cut for standard slotting and profiling depths
• Micrograin solid carbide construction for edge retention and resistance to wear
• 45-degree right-hand spiral flutes for efficient chip evacuation and reduced cutting forces
• Centercutting design allows plunge entry into workpiece material
• Bright uncoated finish suitable for aluminum, non-ferrous alloys, and general-purpose milling
• Mill diameter tolerance of +0.000 / -0.002 inches for predictable dimensional results

Compatibility

Designed as a standard-shank replacement or new-install end mill for CNC machining centers and manual mills accepting 3/4-inch collet or end mill holders. Specific machine compatibility was not stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully de-energized and locked out before changing tooling. Seat the shank fully into the holder to the recommended insertion depth and torque set screws or collet nuts per the holder manufacturer's specifications. Inspect the cutting edges for chips or runout before beginning a cut.
