Accupro 12181697 Square End Mill 1/2 in 2 Flute Carbide Altin

Product Description

The ACCUPRO 12181697 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.5000-inch mill diameter, a 5/8-inch length of cut, and a 2-flute spiral geometry, this tool delivers efficient chip evacuation and clean edge profiles in slotting, profiling, and plunge-cutting applications. The 40-degree helix angle reduces cutting forces and improves surface finish in ferrous and non-ferrous materials. AlTiN coating provides thermal and oxidation resistance, extending tool life in dry or semi-dry high-speed cutting conditions. The micrograin carbide substrate adds toughness at the cutting edge. Installed and used by machinists and CNC operators in production and job-shop settings.

This end mill is suited for milling operations on ferrous metals, stainless steel, high-temperature alloys, and similar materials where heat generation is a concern. The centercutting design allows direct plunge entry into a workpiece without a pre-drilled starting hole. The right-hand cut and right-hand flute configuration are standard for conventional CNC milling center setups. The stub length classification keeps the tool rigid and reduces deflection during aggressive cuts. Overall length is 2.5 inches with a 0.5000-inch shank diameter for direct collet or end-mill-holder mounting.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN coating for high-heat resistance in dry and semi-dry cutting
• 40-degree helix angle reduces cutting forces and improves surface finish
• Centercutting geometry allows direct plunge entry
• 2-flute design promotes chip clearance in slotting and profiling
• Mill diameter tolerance of +0.000 / -0.002 inches for precise fit and consistent results

Compatibility

Designed as a standard shank solid carbide square end mill compatible with 1/2-inch collets, end-mill holders, and hydraulic tool holders used on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the holder to the recommended grip depth before torquing the retention mechanism. Inspect collet or holder for runout before production use, as excessive runout accelerates edge wear on carbide tooling.
