Harvey Tool 53647-C6 Corner Radius End Mill 0.047in 3 Flute

Product Description

The HARVEY TOOL 53647-C6 is a solid carbide corner radius end mill engineered for demanding material removal in steel, stainless steel, cast iron, and hard alloys. It features a 0.047 inch mill diameter with a 0.005 inch corner radius, three flutes, and a variable helix geometry that reduces harmonics and chatter during aggressive cuts. The AlTiN PVD coating provides high-temperature oxidation resistance, making this tool well suited to dry or near-dry machining of difficult alloys. At 2.5 inches overall length with a 0.75 inch length of cut, it balances reach and rigidity for precision finish and roughing operations.

This end mill is designed for use in CNC machining centers working with high-temperature alloys, hardened steels, stainless steel, and cast iron. The single-end, right-hand cut configuration with a straight cylindrical shank fits standard collet and high-precision toolholder setups. The long flute length designation makes it appropriate for applications requiring depth without sacrificing rigidity in the cut zone. Machinists and tooling technicians in production and job-shop environments will find this tool relevant for finishing and semi-roughing passes on hard material components.

Key Features

• Variable helix geometry reduces chatter and harmonics in hard and high-temp alloy cuts
• AlTiN PVD coating delivers heat resistance for dry or minimal-coolant machining
• 0.005 inch corner radius with tolerance of plus or minus 0.0010 inch for controlled edge geometry
• Center-cutting design allows plunge entry as well as peripheral milling
• Right-hand flute direction and right-hand cutting orientation for standard CNC spindle use
• Solid carbide construction provides stiffness and wear resistance in hard materials

Compatibility

Designed for use with high-precision toolholders. Suitable for machining steel, stainless steel, cast iron, and hard alloys. Straight cylindrical shank with h6 shank diameter tolerance fits standard collet chucks and shrink-fit toolholders accepting a 0.125 inch shank.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the shank fully in the toolholder to the recommended gauge length and torque the collet or retention device per the toolholder manufacturer specification. Verify runout at the tool tip with a dial indicator before beginning the cut cycle, as excessive runout accelerates edge wear on small-diameter end mills.
