Kennametal 4048741 Corner Radius End Mill 1 in 5 Flute Altin

Product Description

The KENNAMETAL 4048741 is a solid carbide corner radius end mill from the UCDE series, designed for high-performance material removal in demanding machining environments. Built with a 1-inch diameter and a 0.03-inch corner radius, this single-end tool produces a controlled edge geometry that reduces stress concentrations in finished workpieces. The AlTiN PVD coating provides excellent heat resistance and hardness, making it well-suited for dry or semi-dry cutting conditions. With 5 flutes in a high-helix spiral configuration and a Weldon flat shank, this end mill is engineered for both roughing and finishing operations in steel, stainless steel, cast iron, and other hard materials. A licensed machinist or CNC operator is the typical installer.

This end mill is intended for use in CNC machining centers handling ferrous and hard alloy workpieces, including steel, stainless steel, cast iron, and hard materials classified under material codes P, M, K, and H. The extended reach design, with a 3.25-inch reach length, makes it applicable where standard-reach tools cannot access deeper pockets or shoulders. The long flute length of 1.75 inches supports full-depth slotting and profiling passes in those materials. Compatible toolholding systems include EM-CV Form AD and EM IN-HSK Form A holders.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating rated for high-temperature cutting in ferrous and hard alloy applications
• 5-flute, high-helix spiral geometry supports both roughing and finishing in a single tool
• 0.03-inch corner radius reduces chipping and extends edge life at workpiece corners
• Extended reach of 3.25 inches with a 0.94-inch neck diameter for deep-pocket accessibility
• Weldon flat shank for positive drive and secure retention in compatible toolholders
• Right-hand cut, right-hand flute direction; single-end configuration

Compatibility

Designed for use with EM-CV Form AD and EM IN-HSK Form A toolholding systems. Intended for machining steel, stainless steel, cast iron, and hard materials (material codes P, M, K, H).

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the spindle before mounting or removing the end mill. Seat the Weldon flat against the setscrew in the toolholder and torque the setscrew per the toolholder manufacturer specification. Verify runout at the tool tip with a dial indicator before initiating a cut, and confirm that cutting parameters match the material grade and coating requirements for this tool.
