Walter-prototyp 8415059 Corner Radius End Mill 1/2 in 5 Flute

Product Description

The WALTER-PROTOTYP 8415059 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining applications. Built to a 1/2 inch diameter with a 0.0300 inch corner radius and five flutes, it balances cutting efficiency with edge strength across roughing and finishing passes. The TiAlN/THL dual coating, designated WJ30TF, provides thermal resistance and extended tool life under elevated cutting temperatures. With a 1 inch length of cut and 3 inch overall length, this single-end mill is suited for CNC machining centers where consistent dimensional accuracy is required. It is installed and operated by machinists and tooling professionals working in precision metalworking environments.

This end mill is engineered for primary use in steel (material code P) and extends to cast iron (K), stainless steel (M), and superalloys and titanium (S). The right-hand flute direction and right-hand cutting geometry make it compatible with standard CNC spindle configurations. The straight cylindrical shank with h6 tolerance provides consistent tool holding in collet chucks and hydraulic holders. It carries no chipbreaker geometry, making it appropriate for applications requiring clean surface finishes alongside aggressive material removal. This tool belongs to the MA230.A-5-R-C series and is cataloged under manufacturer number MA230.12.7A5S076C-WJ30TF.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard metal cutting
• TiAlN/THL (WJ30TF) coating for high-temperature performance and extended tool life
• Five-flute design supports both roughing and finishing in a single tool
• 0.0300 inch corner radius reduces stress concentration and improves edge durability
• 38 degree helix angle promotes efficient chip evacuation in deep cuts
• Straight cylindrical shank with h6 tolerance for precise tool holding

Compatibility

Designed for use in CNC machining centers with standard 1/2 inch collet or hydraulic tool holders. Primary workpiece material is steel; secondary materials include cast iron, stainless steel, superalloys, and titanium as specified by the manufacturer for this series.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling setup procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or unloading the tool. Seat the shank fully into the holder and torque the collet nut to the holder manufacturer's specification. Verify runout with a dial indicator before engaging the workpiece, as excessive runout accelerates carbide edge wear.
