Harvey Tool 45285 Corner Radius End Mill 0.085 in Solid Carbide

Product Description

The HARVEY TOOL 45285 is a solid carbide corner radius end mill designed for precision milling in demanding applications. It features an 0.0850-inch cutting diameter with a 0.0100-inch corner radius, delivering controlled edge geometry that reduces stress concentration at the cutting corner and extends tool life. The 2-flute, single-end configuration supports both roughing and finishing passes. With a 30-degree helix angle and bright/uncoated finish, this miniature end mill suits tight-tolerance work in steel, stainless steel, cast iron, and non-ferrous metals. It belongs to the Harvey Tool Miniature End Mills - Corner Radius - Stub and Standard series and is installed by machinists and CNC operators in precision machining environments.

This end mill is suited for use in CNC milling centers and manual mills where small-diameter, close-tolerance work is required. The 2-inch length of cut accommodates deeper pocket and slot operations within its miniature form factor. Compatible primary workpiece materials include steel, stainless steel, cast iron, aluminum, wood, and composites. The straight cylindrical shank fits standard 1/8-inch toolholders. Centercutting capability allows direct plunge entry where the application permits.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 0.0100-inch corner radius with a tolerance of plus or minus 0.0010 inches for consistent edge geometry
• Centercutting design allows direct plunge milling without pre-drilling
• Right-hand cut and right-hand flute spiral with 30-degree helix angle for efficient chip evacuation
• Bright/uncoated finish compatible with a wide range of workpiece materials and cutting fluids
• Single-end, coarse pitch configuration suited for both roughing and finishing operations

Compatibility

Designed for use with standard 1/8-inch straight cylindrical toolholders. Primary workpiece material compatibility includes steel, stainless steel, cast iron, aluminum, wood, and composite materials per manufacturer specifications.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool changer or quill is locked before installing or removing the end mill. Seat the shank fully in the toolholder and torque the set screw or collet to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut, as miniature-diameter tools are sensitive to even minor concentricity errors.
