Harvey Tool 949112 Corner Radius End Mill 0.187 in 3 Flute

Product Description

The HARVEY TOOL 949112 is a solid carbide corner radius end mill built for precision milling in tight-tolerance applications. It carries a 0.187 inch (3/16 inch) mill diameter, a 0.06 inch corner radius with a tolerance of plus or minus 0.001 inch, and three right-hand helical flutes at a 30-degree helix angle. The 3-inch overall length and extended long-reach geometry make it well suited for deep-pocket work where standard-length tools cannot reach. Rated for both roughing and finishing passes, this single-end, center-cutting tool is used by machinists and CNC operators working in job shops, toolrooms, and production environments.

This end mill is designed for milling steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials. The stub flute configuration with a 9/32 inch length of cut limits deflection while the extended reach of 1 inch provides clearance in deep slots and stepped pockets. The straight cylindrical shank at 3/16 inch diameter mounts directly into standard end mill holders or collet chucks. The bright uncoated carbide finish makes it a general-purpose choice where a specific coating is not required by the application.

Key Features

• 0.06 inch corner radius with a tight tolerance of plus or minus 0.001 inch for consistent blending of floors and walls
• Solid carbide construction for rigidity and wear resistance across ferrous and non-ferrous materials
• Extended long-reach geometry with 1 inch reach length for deep-pocket and hard-to-access features
• Center-cutting capability allows plunge entry without a pre-drilled pilot hole
• 3-flute, right-hand helical design supports both roughing and finishing in a single tool
• Stub flute length minimizes deflection during extended-reach cuts

Compatibility

Designed for use with standard end mill toolholders and collet chucks accepting a 3/16 inch straight cylindrical shank. Suited for CNC machining centers and manual mills running steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite workpieces.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention mechanism to the toolholder specification before running. Verify runout with a dial indicator after mounting, particularly given the small diameter, to avoid premature tool failure at extended reach.
