Kennametal 5351896 Corner Radius End Mill 0.75in 6 Flute Altin

Product Description

The KENNAMETAL 5351896 is a solid carbide corner radius end mill designed for high-performance milling in demanding materials including steel, stainless steel, superalloys, titanium, and hard materials. It features a 0.75 inch mill diameter, a 0.12 inch corner radius, and 6 flutes in a right-hand spiral configuration with a close pitch. The AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and extended tool life in high-heat cutting environments. Intended for finishing operations, this single-end, centercutting tool is suited for machinists and tool-room operators working in CNC machining centers and high-precision milling applications.

This end mill is built for finishing passes in ferrous and exotic alloy workpieces. Its short-length geometry and high helix style promote chip evacuation and surface finish quality. The Safe-Lock shank design provides pull-out resistance in high-torque milling operations. It is compatible with hydraulic chuck toolholders and is well suited for aerospace, die-mold, and precision manufacturing environments where tight tolerances and material hardness demand a submicron carbide grade with a durable PVD coating.

Key Features

• 6-flute, right-hand spiral geometry optimized for finishing in hard and exotic alloys
• AlTiN PVD coating for thermal resistance and extended tool life in high-heat cuts
• 0.12 inch corner radius reduces stress concentration and improves surface finish
• Safe-Lock shank design resists pull-out in high-torque hydraulic chuck setups
• Centercutting design allows plunge entry without a pre-drilled hole
• Submicron carbide grade for improved hardness and edge retention in P, M, S, and H material groups

Compatibility

Designed for use with HC 1/2 through HC 1-1/4 Hydraulic Sleeves (inch bore), HC 20M through HC 32M Hydraulic Sleeves (metric sleeve with inch bore), HC-HSK Form A holders, and Hydraulic Chuck Standard Line Inch KM63XMZ toolholders. Rated for steel, stainless steel, superalloys, titanium, and hard material workpiece applications (ISO material codes P, M, S, H).

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and clamping specifications. Ensure the machine spindle is fully powered down and the tool changer is in a safe state before mounting or removing the end mill. Use the correct hydraulic chuck or Safe-Lock compatible holder to prevent axial pull-out under cutting loads. Inspect the cutting edges and corner radius for chipping before each use, particularly after cuts in hard or abrasive materials.
