Harvey Tool 53710-C6 Corner Radius End Mill 4 Flute Altin

Product Description

The HARVEY TOOL 53710-C6 is a solid carbide corner radius end mill engineered for high-temperature alloy machining and general precision milling in steel, stainless steel, cast iron, and hard materials. It carries a 0.0150 inch corner radius, a 5/32 inch (0.1562 inch) mill diameter, and a 3/4 inch length of cut. The AlTiN PVD coating provides thermal resistance and oxidation protection during aggressive cuts. A variable helix geometry reduces harmonic vibration, improving surface finish and tool life in difficult materials. Machinists and toolroom operators working with tight tolerances will find the 4-flute, right-hand spiral configuration effective for both roughing and finishing passes in a single setup.

This end mill is suited for CNC milling operations in job shops, aerospace, medical device, and precision manufacturing environments where high-temp alloys, hardened steels, and stainless grades are common workpiece materials. The centercutting design allows plunge entry, adding flexibility to slotting and pocket-milling operations. With a 3/16 inch straight-cylindrical shank, it seats in standard high-precision toolholders. The long-length classification and 3 inch overall length extend reach for deeper features without requiring a custom extension. Installation is straightforward in any collet or hydraulic chuck rated for the 3/16 inch shank diameter.

Key Features

• Variable helix geometry reduces chatter and vibration in high-temp alloy cuts
• AlTiN PVD coating provides oxidation and heat resistance at elevated cutting temperatures
• Centercutting design enables direct plunge entry for slot and pocket milling
• 4-flute, right-hand spiral supports both roughing and finishing material removal
• 0.0150 inch corner radius with a tight tolerance of plus or minus 0.0010 inch protects corners and reduces stress concentration
• Solid carbide construction maintains rigidity and edge integrity in hard and abrasive workpiece materials

Compatibility

Designed for use with high-precision toolholders in CNC milling applications. Primary workpiece materials include steel, stainless steel, cast iron, and hard alloys. Part of the Harvey Tool Variable Helix End Mills for High Temp Alloys - Corner Radius and Material Specific End Mills series.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Seat the 3/16 inch straight-cylindrical shank fully into a high-precision collet or hydraulic chuck before torquing the toolholder to the spindle manufacturer's specification. Ensure the machine spindle is at a complete stop and the CNC controller is in an E-stop or locked-out state before changing tooling. Do not exceed the toolholder's rated runout tolerance, as excessive runout will accelerate wear on a small-diameter end mill of this type.
