Accupro 12183675 Corner Radius End Mill 5/16 in 4 Flute Ticn

Product Description

The ACCUPRO 12183675 is a solid carbide corner radius end mill designed for precision milling of ferrous and hard materials. It features a 5/16-inch diameter, a 0.045-inch corner radius, and a TiCN (Titanium Carbonitride) coating that extends tool life by reducing friction and resisting wear. With four flutes and a right-hand spiral flute direction, this end mill delivers efficient chip evacuation and smooth surface finishes. The extra-long 6-inch overall length and 1-1/2-inch length of cut make it well-suited for deep-pocket and extended-reach milling applications. It is centercutting capable, allowing direct plunge entry into workpiece material.

This end mill is intended for use on CNC machining centers and manual mills in job shop, production, and toolroom environments. The TiCN coating and micrograin carbide substrate make it particularly effective when cutting alloy steels, stainless steels, and other demanding materials. The single-end configuration and 40-degree helix angle contribute to stable cutting performance in deep-cavity and contour milling operations where reach is a primary concern.

Key Features

• 5/16-inch mill diameter with micrograin solid carbide construction for rigidity and wear resistance
• 0.045-inch corner radius reduces stress concentrations and extends tool life in corner milling
• TiCN coating provides enhanced hardness and lubricity compared to uncoated carbide
• 4-flute, right-hand spiral design for efficient chip removal and smooth finish
• Centercutting geometry allows direct plunge milling without pre-drilling
• Extra-long 6-inch OAL with 1-1/2-inch LOC supports deep-pocket and extended-reach operations

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool compatible with standard 5/16-inch collets, end mill holders, and shrink-fit tooling systems on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and machine is in a safe state before loading or unloading the tool. Seat the 5/16-inch shank fully into the holder and torque the retention mechanism according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning cuts, particularly given the extra-long reach of this tool.
