Accupro 12183532 Corner Radius End Mill 3/8 in 4 Flute Ticn

Product Description

The ACCUPRO 12183532 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 3/8 inch diameter, a 1 inch length of cut, and a 0.01 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. The TiCN coating provides enhanced hardness and wear resistance compared to uncoated carbide. With 4 right-hand spiral flutes and a 40-degree helix angle, this single-end, centercutting tool handles both plunging and contouring. It is installed and operated by machinists and tool-and-die professionals running CNC machining centers or manual mills.

This end mill is suited for finish milling, profiling, and slotting operations where a small corner radius is required to strengthen the tool corner and produce consistent edge geometry. The long-length configuration and 4 inch overall length make it appropriate for applications requiring extended reach into pockets or along vertical walls. It is a common choice in job shops, toolrooms, and production machining environments working with steel, stainless steel, cast iron, and similar materials where TiCN coating performance is beneficial.

Key Features

• 3/8 inch mill diameter with micrograin solid carbide construction for rigidity and edge retention
• 0.01 inch corner radius reduces chipping at the cutting edge and improves surface finish
• TiCN coating provides increased wear resistance and hardness for extended tool life
• 4 right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Single-end configuration with 3/8 inch shank diameter for standard collet and toolholder compatibility

Compatibility

Designed as an OEM-style replacement and standard fitment for CNC machining centers and manual mills accepting a 3/8 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and the tool is secured with adequate collet or toolholder engagement along the shank before operation. Verify runout with a dial indicator after installation to confirm proper seating. Follow the machine tool manufacturer and cutting tool supplier recommendations for speeds, feeds, and depth of cut for the workpiece material.
