Iscar 5680944 Corner Radius End Mill 1/2 in 5 Flute Carbide

Product Description

The ISCAR 5680944 is a solid carbide corner radius end mill designed for high-performance milling operations in ferrous and non-ferrous materials. With a 1/2 inch cutting diameter and a 0.1 inch corner radius, it produces smooth, radiused edges while reducing stress concentrations at corners. The 5-flute variable-pitch geometry paired with a 38-degree helix angle promotes chip evacuation and surface finish quality. AlTiN coating adds thermal hardness and oxidation resistance, making this tool well-suited for dry or high-speed cutting environments. Machinists and CNC operators install this end mill for finishing and semi-finishing passes where corner integrity matters.

This end mill is suited for use in CNC machining centers handling profiling, slotting, and contouring operations. The 1-1/4 inch length of cut accommodates moderate-depth passes, while the 3 inch overall length and 1/2 inch shank diameter fit standard ER and side-lock toolholders. The centercutting design allows plunge entry directly into the workpiece. Variable pitch reduces harmonic chatter, which is especially useful on long-run production cycles or when machining harder alloys.

Key Features

• 0.1 inch corner radius reduces stress risers and improves part longevity
• 5-flute variable-pitch design minimizes chatter and supports higher feed rates
• 38-degree right-hand helix promotes chip flow and surface finish
• AlTiN coating provides thermal resistance for dry and high-speed cutting
• Centercutting geometry enables direct plunge entry
• Right-hand cutting and flute direction for standard spindle operation

Compatibility

Designed as a direct-fit replacement for 1/2 inch shank end mill holders used in CNC machining centers and manual mills accepting standard straight-shank tooling.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set screw torque meets the toolholder manufacturer's specification. Inspect the cutting edges and coating for damage before each use; do not run a chipped or worn tool at rated parameters.
