Accupro 2500185 Square End Mill 1/2 in 3 Flute Carbide

Product Description

The ACCUPRO 2500185 is a solid carbide square end mill designed for precision milling operations in metal, composites, and hard materials. Built from micrograin carbide, this single-end tool features a 1/2 inch cutting diameter, a 1 inch length of cut, and a 60-degree helix angle that promotes aggressive chip evacuation and reduced cutting forces. The bright uncoated finish makes it well-suited for applications where coating buildup could affect dimensional accuracy. It is installed and operated by machinists and tool-and-die professionals on CNC machining centers and manual knee mills.

This end mill is used in general-purpose milling, slotting, profiling, and peripheral cutting. The 3-flute configuration balances chip clearance with cutting edge contact, making it effective for both ferrous and non-ferrous materials. The right-hand cut and right-hand spiral flute direction are standard for conventional CNC setups. With a 3-inch overall length and 1/2 inch shank diameter, it fits directly into standard ER or end mill holders without adapters in most setups.

Key Features

• 1/2 inch cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inches
• 60-degree helix angle for aggressive chip evacuation and reduced cutting forces
• Micrograin solid carbide construction for rigidity and wear resistance
• 3-flute spiral design balances chip clearance and surface contact
• Centercutting geometry allows plunge entry into workpiece
• Bright uncoated finish suitable for dry cutting or water-soluble coolant applications

Compatibility

Designed as a standard 1/2 inch shank square end mill compatible with ER collet chucks, end mill holders, and similar toolholding systems used on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the minimum recommended insertion depth for your holder and torque the retention mechanism per the holder manufacturer specifications. Verify runout with a dial indicator before beginning any production cut.
