Kennametal 3755915 Corner Radius End Mill 0.5in 3 Flute

Product Description

The KENNAMETAL 3755915 is a solid carbide corner radius end mill designed for high-performance material removal in non-ferrous metal applications. Built to the ABDE series standard, it features a 0.5-inch mill diameter, a 0.12-inch corner radius, and three right-hand spiral flutes with a high helix angle of 45 degrees. The bright, uncoated finish makes it well-suited for aluminum, copper, brass, and similar non-ferrous workpiece materials where coating adhesion or heat-related edge buildup can be a concern. Licensed machinists and CNC programmers specify this tool for roughing operations that demand consistent corner geometry and extended reach capability.

This end mill is configured as a single-end, centercutting tool with a straight cylindrical shank measuring 0.5 inches in diameter. The 0.625-inch length of cut, 6-inch overall length, and 3.375-inch reach length support deep-cavity and extended-reach setups on vertical machining centers and CNC mills. It is primarily applied in production and job-shop environments working non-ferrous stock where coarse pitch fluting improves chip evacuation and reduces cutting forces during aggressive roughing passes.

Key Features

• 0.12-inch corner radius protects the tool edge and improves surface finish at part corners
• Three-flute, high-helix spiral design promotes efficient chip evacuation in non-ferrous materials
• Submicron solid carbide grade provides rigidity and wear resistance without a coating
• Centercutting geometry allows plunge entry cuts
• Extended reach of 3.375 inches suits deep-pocket and cavity machining setups
• Right-hand cutting and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed for use with standard end mill toolholders. Intended for primary use in non-ferrous metal applications as identified by material code N. No specific compatible machine models were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Secure the 0.5-inch straight shank in a properly sized end mill holder or collet chuck, ensuring adequate shank engagement per the toolholder manufacturer guidelines. Verify spindle speed and feed rate are set for non-ferrous material and the selected depth of cut before engaging the workpiece. Never exceed the tool's rated length of cut or reach without engineering review of the setup.
