Kennametal 4046385 Corner Radius End Mill 10mm 5 Flute Carbide

Product Description

The KENNAMETAL 4046385 is a solid carbide corner radius end mill engineered for demanding metal removal in steel, stainless steel, cast iron, and hard materials. It features a 10 mm cutting diameter, a 22 mm length of cut, and a 0.51 mm corner radius that protects the cutting edge and reduces chipping at the tool nose. The five-flute geometry with a high helix style supports both roughing and finishing passes in a single tool, making it a practical choice for machinists and tooling setups where tool changes need to be minimized. An AlTiN PVD coating provides thermal resistance and wear protection at elevated cutting temperatures.

This end mill belongs to the KENNAMETAL UCDE series and is designed for use in CNC milling centers handling steel, stainless steel, cast iron, and hard workpiece materials (ISO material groups P, M, K, and H). The single-end, right-hand cutting configuration with a Weldon flat shank suits standard side-lock toolholders. The long length type and 72 mm overall length make it appropriate for applications requiring extended reach into pockets or along deep walls. It is compatible with ER single angle standard collets.

Key Features

• Solid carbide submicron-grade construction for toughness in hard and abrasive materials
• AlTiN PVD coating for high-temperature wear resistance and extended tool life
• Five-flute design supports both roughing and finishing in a single pass
• 0.51 mm corner radius reduces edge chipping and stress concentration at the tool nose
• Weldon flat shank for positive engagement in side-lock and collet toolholders
• Right-hand flute direction and cutting direction for standard CNC spindle use

Compatibility

Designed for use with ER single angle standard collets and Weldon flat side-lock toolholders. Suitable for machining steel, stainless steel, cast iron, and hard materials across ISO material groups P, M, K, and H. Part of the KENNAMETAL UCDE series.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool turret is locked out before changing tooling. Seat the Weldon flat securely against the setscrew in the toolholder to prevent axial pullout under cutting loads. Verify runout with a dial indicator after clamping before engaging the workpiece.
