Accupro 12182384 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The ACCUPRO 12182384 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and consistent chip evacuation. Built from micrograin solid carbide with a TiCN (Titanium Carbonitride) coating, this tool delivers improved wear resistance and surface finish performance in ferrous and non-ferrous materials. It features a 1/8 inch cutting diameter, a 0.015 inch corner radius, and four right-hand spiral flutes with a 40-degree helix angle. The single-end, centercutting design allows plunge entry and versatile toolpath options. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.

This end mill is suited for finish milling, profiling, and contouring operations where a small but defined corner radius is required to reduce stress concentration in part geometry. With a 1/2 inch length of cut and 1-1/2 inch overall length, it is well matched to shallow-to-moderate depth passes on parts requiring tight dimensional tolerances. The 1/8 inch shank diameter fits standard collet toolholding systems common on CNC machining centers and manual mills. The TiCN coating extends tool life when cutting steels, stainless, and hardened alloys compared to uncoated carbide.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention in demanding cuts
• TiCN coating provides enhanced hardness and reduced built-up edge on ferrous materials
• 0.015 inch corner radius reduces edge chipping and improves part surface finish at corners
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use corner radius end mill for standard 1/8 inch collet or toolholding systems on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1/8 inch shank fully into a clean, properly sized collet and torque the collet nut to the toolholder manufacturer's specification. Verify runout at the cutting end before beginning the operation to protect both the tool and the workpiece.
