Harvey Tool 933309-C6 Corner Radius End Mill 0.1406 in 5 Fl

Product Description

The HARVEY TOOL 933309-C6 is a solid carbide corner radius end mill designed for high-performance cutting in hardened steels, stainless steel, cast iron, and hard alloys up to 55 Rc. It measures 0.1406 inches in diameter with a 2.5-inch overall length and a 0.25-inch length of cut. The five-flute, single-end configuration features a variable helix and a 0.0050-inch corner radius for edge strength and chip control. An AlTiN Nano PVD coating provides thermal resistance and surface hardness for sustained cutting in demanding materials. This tool is suited for machining operations requiring both roughing and finishing capability in a single pass.

This end mill is engineered for use in hardened steel applications up to 55 Rc, making it appropriate for die and mold work, toolroom operations, and precision part machining in steel and stainless steel. The 0.25-inch straight-cylindrical shank fits standard collet chucks and high-precision toolholders. Its close pitch and right-hand cutting direction support stable, controlled material removal in tight-tolerance work. Machinists and CNC operators working in production shops and toolrooms will find this part suited to small-diameter finishing and semi-finishing passes in hardened materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in hardened materials
• AlTiN Nano PVD coating for thermal protection and extended tool life in ferrous materials
• Variable helix flute geometry reduces chatter and improves surface finish
• 0.0050-inch corner radius protects cutting edge and reduces stress concentration
• Centercutting design allows plunge entry in addition to peripheral cuts
• Rated for steels up to 55 Rc, including cast iron, stainless steel, and hard alloys

Compatibility

Designed for use with high-precision toolholders. Rated for primary workpiece materials including steel, stainless steel, cast iron, and hard alloys. Belongs to the Harvey Tool End Mills for Hardened Steels - Corner Radius series for steels up to 55 Rc.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and the spindle fully stopped. Use a high-precision collet or shrink-fit toolholder to ensure runout is minimized at this diameter. Verify shank seating depth and clamping torque per the toolholder manufacturer's specifications before operation. Follow your facility's lockout/tagout procedures before any tool change on CNC or manual milling equipment.
