Promax 119-03214 Corner Radius End Mill 1/2 in 3 Flute Altin

Product Description

The PROMAX 119-03214 is a solid carbide corner radius end mill engineered for combined roughing and finishing operations in a single pass. Built to Series 119 standards, it features a 1/2 inch diameter, three flutes, and a 0.02 inch corner radius on a corner radius end geometry. The AlTiN coating provides heat resistance and extended tool life in ferrous and hardened materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool is intended for use by machinists and tool-and-die professionals in CNC milling applications where surface finish and dimensional accuracy both matter.

This end mill is suited for use in vertical and horizontal CNC machining centers handling steel, stainless steel, cast iron, and similar ferrous alloys. The corner radius geometry reduces stress concentration at the cutting edge, making it a reliable choice for pocket milling, profiling, and contour work where a sharp corner would risk chipping. The single-end, right-hand cutting configuration is standard for most CNC milling setups. Micrograin carbide construction supports use at elevated surface speeds.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for thermal protection and extended tool life in ferrous materials
• 0.02 inch corner radius reduces edge chipping and improves surface finish
• 40-degree right-hand helix for efficient chip evacuation
• Center-cutting capable - supports plunge and ramp entry
• Straight-cylindrical shank with tight shank diameter tolerance for secure toolholder grip

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC milling machines accepting a 1/2 inch straight-cylindrical shank end mill, including ER, side-lock, and shrink-fit toolholders sized for 1/2 inch shanks.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Verify toolholder bore cleanliness and proper pullout force before beginning a cut. Do not exceed the toolholder manufacturer's recommended overhang length for the selected holder type.
