Accupro 12183373 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The ACCUPRO 12183373 is a solid carbide corner radius end mill designed for precision milling operations in metal-cutting applications. It features a 3/4-inch mill diameter with a 0.01-inch corner radius that reduces stress concentrations at part corners and extends tool life in demanding cuts. The 3-inch length of cut and 6-inch overall length make this an extra-long reach tool suited for deep-pocket and step milling work. A TiCN coating provides enhanced hardness and lubricity compared to uncoated carbide, improving performance in ferrous and non-ferrous materials. This tool is installed and run by machinists and CNC operators in production and job-shop environments.

This end mill is well suited for milling operations requiring corner radii on steel, stainless steel, cast iron, and similar materials. The extra-long flute length accommodates deep-pocket work where standard-length tools cannot reach. The single-end, centercutting design allows both plunge and peripheral cutting. Right-hand flute direction and right-hand cutting rotation are standard for conventional CNC machining center setups. Micrograin carbide substrate supports sharp, stable cutting edges at elevated speeds and feeds.

Key Features

• 0.01-inch corner radius reduces edge chipping and stress risers on workpiece corners
• TiCN coating improves wear resistance and surface lubricity for longer tool life
• Extra-long 3-inch length of cut enables deep-pocket and step milling
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate maintains edge integrity at high cutting parameters
• Right-hand spiral flutes with 40-degree helix promote efficient chip evacuation

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 3/4-inch straight shank end mill.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into a collet or end mill holder to the recommended grip depth and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts.
