Accupro 12182255 Square End Mill 1/2 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12182255 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 3-inch length of cut, and a 6-inch overall length, this extra-long end mill reaches deep into workpieces where standard-length tools cannot. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Finished with AlTiN coating, it handles elevated cutting temperatures common in high-speed ferrous and exotic alloy machining. This tool is installed and operated by machinists and CNC programmers working in job shops, aerospace, and general manufacturing.

This end mill is suited for slotting, profiling, and peripheral milling on ferrous metals, hardened steels, stainless, and similar materials where AlTiN coating provides thermal resistance. The extra-long length type makes it appropriate for deep-cavity milling, long-reach applications, and setups where toolholder clearance demands additional reach. Centercutting geometry allows plunge entry, expanding its application flexibility on machining centers and CNC mills.

Key Features

• Solid carbide micrograin substrate for rigidity and wear resistance in hard materials
• AlTiN finish provides heat and oxidation resistance at elevated cutting speeds
• 40-degree helix spiral flute promotes aggressive chip evacuation and reduced cutting force
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute configuration for standard CNC spindle use
• Extra-long length type with 3-inch length of cut for deep-reach milling applications

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill compatible with standard 1/2 inch collet or end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Secure the 0.5000 inch shank in a properly sized collet, shrink-fit holder, or end mill holder rated for the spindle speed and cutting forces of the application. Verify runout at the tool tip before production cutting. Follow machine tool manufacturer guidelines and applicable shop safety procedures when handling carbide tooling.
