Accupro 12182145 Corner Radius End Mill 3/4 in 3 Flute

Product Description

The ACCUPRO 12182145 is a solid carbide corner radius end mill designed for high-performance milling operations in metal fabrication, tool and die, and precision machining environments. It features a 3/4 inch diameter with a 0.045 inch corner radius that reduces stress concentrations at part edges and extends tool life in demanding cuts. The 1-1/2 inch length of cut and AlTiN coating make it well suited for elevated-temperature applications in hardened steels and aerospace alloys. Machinists and tool room operators select this end mill for finish and semi-finish passes where edge integrity matters.

This end mill fits CNC machining centers and manual mills with a 3/4 inch collet or end mill holder. The single-end, centercutting design supports plunge entry as well as conventional and climb milling passes. It is appropriate for applications in ferrous metals, stainless steel, titanium, and high-temp alloys where an AlTiN coating provides thermal protection and extended edge life at higher surface footage. The right-hand spiral flute geometry promotes chip evacuation in slotting and profiling operations.

Key Features

• 0.045 inch corner radius reduces edge chipping and workpiece stress risers
• AlTiN coating provides oxidation resistance and hardness at elevated cutting temperatures
• 3-flute micrograin solid carbide construction for rigidity and wear resistance
• Centercutting geometry allows direct plunge entry without pre-drilling
• 40-degree helix angle promotes aggressive chip flow and smooth surface finish
• Right-hand cut and right-hand spiral for use on standard CNC and manual milling setups

Compatibility

Designed for use in standard 3/4 inch end mill holders, collet chucks, and shrink-fit tooling systems on CNC machining centers and manual knee mills requiring a single-end corner radius end mill.

Installation Notes

Installation and tool changes should be performed with the machine in a full stop, zero-energy state per shop lockout/tagout procedures. Seat the shank fully in the holder and torque the retention mechanism to the toolholder specification before engaging the spindle. Inspect the cutting edges and corner radius for chips or wear before each run. Verify runout at the tool tip after installation to maintain dimensional accuracy and maximize tool life.
