Accupro 12183169 Corner Radius End Mill 1in 4 Flute Carbide

Product Description

The ACCUPRO 12183169 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 1-inch diameter, a 3-inch length of cut, and a 0.01-inch corner radius that reduces stress concentration at the cutting edge and extends tool life in roughing and finishing passes. The TiCN coating improves surface hardness and wear resistance, making it well suited for ferrous and non-ferrous materials. With 4 right-hand spiral flutes and a 40-degree helix angle, this single-end, centercutting tool handles slot milling, profiling, and plunging. It is installed and operated by machinists and CNC programmers in production shop environments.

This end mill is configured for extra-long reach applications where standard-length tools cannot access deep pockets or tall workpiece features. The 6-inch overall length and 1-inch shank diameter make it compatible with standard CAT, BT, or collet-style toolholders used on vertical and horizontal machining centers. The micrograin carbide substrate supports tight tolerances and consistent edge geometry across high-volume runs in steel, stainless, cast iron, and similar materials.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating for increased surface hardness and reduced tool wear
• 0.01-inch corner radius reduces chipping and extends cutter life at corners
• 4 right-hand spiral flutes with 40-degree helix for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Extra-long configuration (6-inch OAL) for deep-pocket and extended-reach operations

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC machining centers and manual mills accepting a 1-inch shank diameter toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following standard toolholder torque and runout verification procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm shank seating depth and runout with a dial indicator before beginning a cut. Follow the toolholder manufacturer's clamping specifications to avoid shank damage or pullout under load.
