Promax 119-00814 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The PROMAX 119-00814 is a solid carbide corner radius end mill designed for roughing and finishing operations in a single tool. Built from micrograin solid carbide and coated with AlTiN for heat resistance, it handles hard and abrasive materials at elevated cutting speeds. The 1/8 inch diameter cutter carries a 0.01 inch corner radius and three flutes arranged in a right-hand, 40-degree helix for efficient chip evacuation and smooth surface finishes. A straight cylindrical shank at 1/8 inch diameter provides positive tool holding in standard collets or end mill holders. Machinists and CNC operators working in job shops, mold and die, and aerospace applications rely on this geometry for tight-tolerance work in a compact diameter range.

This end mill suits applications where both stock removal and finish quality are required without a tool change. The corner radius geometry reduces chipping at the cutting edge compared to a sharp corner, extending tool life in ferrous and non-ferrous materials. With a 1/2 inch length of cut and 1-1/2 inch overall length, it is well suited for shallow-to-moderate depth pockets, slots, and profile passes on CNC machining centers and manual mills with appropriate spindle speed and feed control.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating provides high-temperature resistance and extended tool life at aggressive feeds and speeds
• 0.01 inch corner radius reduces edge chipping and improves surface finish at floor-to-wall transitions
• 40-degree right-hand helix promotes efficient chip evacuation during both roughing and finishing passes
• Single-end, center-cutting design allows plunge entry and full-slot cutting
• Straight cylindrical shank fits standard ER collets and end mill holders

Compatibility

Designed as a Series 119 replacement or direct-select solid carbide corner radius end mill for use in CNC machining centers and manual mills accepting a 1/8 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank to the full recommended collet engagement depth before tightening to manufacturer torque specifications for the holder type in use. Verify runout at the tool tip with a dial indicator before beginning a production cut. Power down and lock out the spindle before changing tooling per applicable machine safety procedures.
