Harvey Tool 893912 Corner Radius End Mill 3/16 in 3 Flute

Product Description

The HARVEY TOOL 893912 is a solid carbide corner radius end mill designed for high-performance material removal in aluminum alloys, steel, stainless steel, cast iron, and composite materials. Built with a variable helix geometry, this single-end tool measures 3/16 inch (0.1875 inch) in diameter with a 0.03 inch corner radius and a 0.285 inch length of cut. The 3-flute configuration supports both roughing and finishing operations, making it a versatile choice for machinists working on precision components. It is right-hand cutting with right-hand flute direction and runs uncoated for applications where coating is not required.

This end mill is suited for milling aluminum alloys and is also rated for use in steel, stainless steel, cast iron, wood, and composite workpiece materials. The short flute length and straight cylindrical shank make it appropriate for close-tolerance work in CNC machining centers. It is recommended for use with high-precision toolholders. The variable helix design helps reduce chatter and improve surface finish across a range of cutting conditions. Machinists in aerospace, mold, and general metalworking shops will find this tool applicable to slotting, profiling, and contour milling tasks.

Key Features

• Variable helix geometry reduces vibration and chatter during cutting
• 0.03 inch corner radius protects the cutting edge and improves corner strength
• 3-flute solid carbide construction supports both roughing and finishing passes
• Center-cutting capable, allowing plunge entry into the workpiece
• Uncoated bright finish suitable for aluminum and non-ferrous applications
• Straight cylindrical shank with h6 tolerance for secure toolholder grip

Compatibility

Designed for use in the HARVEY TOOL Variable Helix End Mills for Aluminum Alloys - Corner Radius series. Recommended for use with high-precision toolholders. Rated for primary workpiece material codes P, M, K, N, and O, covering steel, stainless steel, cast iron, non-ferrous metals, and non-ISO materials.

Installation Notes

Installation should be performed by a qualified machinist following standard CNC tooling procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a high-precision toolholder to maintain runout control and maximize tool life. Verify that feed rates and speeds are appropriate for the workpiece material before beginning a cut.
