Accupro 12183094 Corner Radius End Mill 1/2 in 4 Flute Ticn

Product Description

The ACCUPRO 12183094 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), it delivers hardness and wear resistance suited for ferrous and non-ferrous materials. The 0.0600 inch corner radius reduces stress concentration at the cutting edge, extending tool life in demanding applications. With a 1/2 inch mill diameter, 2 inch length of cut, and a 4-flute right-hand spiral configuration, this tool balances chip evacuation with surface finish quality. It is installed and operated by machinists and CNC programmers in production and job shop settings.

This end mill fits standard 1/2 inch toolholders and collet chucks on vertical machining centers, CNC mills, and manual knee mills. The long-length design with a 4 inch overall length suits deeper shoulder milling, slotting, and profiling passes where additional reach is required. Its center-cutting capability allows plunge entry without a pre-drilled pilot hole, giving it flexibility across a range of toolpath strategies in both roughing and finishing operations.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention in hard materials
• TiCN coating provides elevated surface hardness and reduced friction at the cutting edge
• 0.0600 inch corner radius reduces chipping and extends tool life versus sharp-corner geometry
• 4-flute right-hand spiral design balances material removal rate with finish quality
• Center-cutting end allows direct plunge entry without a pilot hole
• 40 degree helix angle improves chip flow and reduces cutting forces on the workpiece

Compatibility

Designed for use in standard 1/2 inch bore toolholders, collet chucks, and shrink-fit holders on CNC and manual milling machines. Suitable for right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following shop-standard tool-change procedures. Ensure the spindle is fully stopped and locked out before seating or removing the tool from the holder. Verify runout with a dial indicator after clamping to confirm proper seating. Follow tool manufacturer recommended surface footage and feed-per-tooth parameters for the workpiece material and coating type before beginning a cut.
