Kennametal 4071914 Corner Radius End Mill 0.5in 4 Flute Altin

Product Description

The KENNAMETAL 4071914 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. It features a 0.5 inch diameter, a 0.015 inch corner radius, and four right-hand spiral flutes with a high helix geometry. The AlTiN PVD coating provides thermal resistance and wear protection at elevated cutting speeds. The extended reach design and 1.25 inch length of cut make it well suited for profiling, slotting, and semi-finish to finish passes on harder workpiece materials. Single-end configuration with a Weldon flat shank ensures positive drive and secure tool holding in compatible holders.

This end mill is built for roughing and finishing operations on steel, stainless steel, cast iron, and hard materials. The HPHV series targets shops running modern CNC machining centers where tool life and surface finish consistency are priorities. The centercutting capability allows plunge entry, giving operators flexibility in toolpath strategies. It is a long-length tool, making it appropriate for deeper cavity work or applications requiring extended reach beyond standard flute geometries.

Key Features

• AlTiN PVD coating for thermal and abrasion resistance in hard and ferrous materials
• High helix flute geometry in the HPHV series for improved chip evacuation and surface finish
• 0.015 inch corner radius reduces stress concentration and extends tool life at cutting edges
• Centercutting design permits plunge and ramping entry cuts
• Weldon flat shank provides positive drive and reduces pullout risk under heavy loads
• Extended reach construction suits deep cavity and long-reach applications

Compatibility

Compatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems per manufacturer data. Designed for use in CNC machining centers running steel, stainless steel, cast iron, and hard material workpieces.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the Weldon flat securely against the setscrew in the holder and verify runout with a dial indicator before cutting. Follow the machine tool manufacturer torque specifications for the toolholder setscrew and consult the KENNAMETAL speeds-and-feeds documentation for this series before first use.
