Kennametal 5351817 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The KENNAMETAL 5351817 is a solid carbide corner radius end mill designed for high-performance milling in demanding ferrous and exotic materials. It features a 1/2 inch diameter cutting edge, a 0.015 inch corner radius, and six flutes in a close-pitch, right-hand spiral configuration. The AlTiN PVD coating provides thermal resistance and oxidation protection, extending tool life in dry or semi-dry cutting conditions. With a 1-1/4 inch length of cut and 3 inch overall length, this end mill is suited for finishing operations where edge integrity and surface finish are critical. It is installed in standard straight-shank end mill toolholders and is specified for CNC machining centers.

This end mill is engineered for finishing applications in steel, stainless steel, superalloys, and hard materials. The UJDE series geometry combines a high helix angle with centercutting capability, making it effective for side milling, slotting, and ramping in tough-to-machine workpieces. Shops running aerospace, die-mold, and precision machining work will recognize this as a tooling-room and production floor staple for tight-tolerance finishing cuts.

Key Features

• AlTiN PVD coating for high-heat resistance in ferrous and hard-material milling
• Six-flute, close-pitch design for improved surface finish and feed rate capability
• 0.015 inch corner radius reduces stress concentration and extends tool life at cutting edges
• Centercutting geometry allows plunge entry and ramp milling
• Right-hand cut, right-hand flute spiral for standard CNC spindle compatibility
• Submicron carbide grade for increased hardness and wear resistance in hard materials

Compatibility

Designed for use with standard end mill toolholders accepting a 1/2 inch straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, superalloys and titanium, and hard materials (material codes P, M, S, H).

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Spindle and machine power must be off and locked out before changing tooling. Seat the shank fully in the toolholder and torque set screws or collet nuts per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut; excessive runout accelerates edge wear on carbide tooling.
