Iscar 5622186 Corner Radius End Mill 1/2 in 3 Flute Carbide

Product Description

The ISCAR 5622186 is a solid carbide corner radius end mill designed for precision milling of non-ferrous metals. It features a 1/2-inch diameter cutting head with a 0.008-inch corner radius, a 1-inch length of cut, and a 3-flute helical geometry that supports both roughing and finishing operations in a single tool. The uncoated fine-grain carbide construction provides sharp edge retention on aluminum, brass, copper, and similar materials. At 3.5 inches overall length with a 1/2-inch straight cylindrical shank, this end mill fits standard toolholders and suits CNC machining centers where tight tolerances and surface finish quality are required.

This end mill is suited for production and job-shop environments running non-ferrous workpieces on vertical or horizontal machining centers. The corner radius geometry reduces stress concentration at the cutting edge, extending tool life on high-speed passes. The single-end, centercutting design allows plunge entry as well as conventional and climb milling. It belongs to the ISCAR ECAI-B-3 series and is classified for use with standard toolholders. The coarse pitch and high helix angle promote efficient chip evacuation in aluminum and other gummy non-ferrous alloys.

Key Features

• 0.008-inch corner radius reduces edge chipping and stress concentration on non-ferrous workpieces
• 3-flute helical geometry supports both roughing and finishing in one pass
• Fine-grain solid carbide construction maintains sharp cutting edges at elevated speeds
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Uncoated bright finish optimized for non-ferrous materials where coatings may cause built-up edge

Compatibility

Designed for use with standard toolholders accepting a 1/2-inch straight cylindrical shank. Intended for non-ferrous metal applications per ISCAR material classification code N. Part of the ISCAR ECAI-B-3 series of solid carbide end mills.

Installation Notes

Installation is performed by machinists or CNC setup technicians using an appropriate collet chuck or end mill holder rated for the 1/2-inch shank diameter. Ensure the toolholder bore and shank surfaces are clean and free of chips before seating. Verify runout with a dial indicator before commencing cuts, as excessive runout will accelerate wear on a 3-flute geometry. Consult machine tool manufacturer documentation and applicable shop safety procedures before spindle operation.
