Kennametal 4048712 Corner Radius End Mill 1/4 in 5 Flute

Product Description

The KENNAMETAL 4048712 is a solid carbide corner radius end mill designed for high-performance milling in demanding materials including steel, stainless steel, cast iron, and hard materials. Built to the UCDE series specification, it features a 1/4 inch diameter, a 3/4 inch length of cut, and a 0.015 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in roughing and finishing passes. The AlTiN PVD coating provides thermal resistance and hardness retention at elevated cutting temperatures. With 5 flutes and a high helix style, this end mill is suited for machinists and tooling professionals running production cuts on CNC machining centers.

This end mill applies to precision milling operations on ferrous and hard materials in both roughing and finishing contexts. The straight cylindrical shank and single-end configuration make it compatible with standard collet and hydraulic toolholding setups. It is specifically noted for use with HC 20M through HC 32M hydraulic sleeves metric with inch bores and the HC-CV Form AD holder system. Typical applications include profiling, contouring, and slot milling in steel and stainless components where corner integrity and surface finish are critical.

Key Features

• 0.015 inch corner radius reduces edge chipping and improves corner strength in hardened and abrasive workpieces
• AlTiN PVD coating delivers high thermal stability and wear resistance for extended tool life in ferrous materials
• 5-flute geometry increases chip load capacity and improves surface finish in finishing passes
• High helix style promotes efficient chip evacuation and reduces cutting forces
• Submicron carbide grade provides consistent edge integrity across roughing and finishing operations
• Single-end, right-hand cut with straight cylindrical shank for direct collet or hydraulic chuck mounting

Compatibility

Designed for use with HC 20M through HC 32M hydraulic sleeves metric with inch bores and the HC-CV Form AD holder system. Suitable for machining steel, stainless steel, cast iron, and hard materials classified under material codes P, M, K, and H.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine in a locked-out state per applicable machine safety procedures. The straight cylindrical shank requires a clean, properly sized collet or hydraulic chuck bore to achieve accurate runout. Inspect the bore and holder for chips or contamination before seating the tool. Verify clamping torque and tool projection against the toolholder manufacturer specifications before beginning a cut.
