Harvey Tool 855320 Corner Radius End Mill 11/64 in 4 Flute

Product Description

The HARVEY TOOL 855320 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous materials. It carries an 11/64 inch (0.1719 inch) cutting diameter, a 0.50 mm (0.0200 inch) corner radius, and a 4-flute right-hand spiral configuration. The stub-and-standard miniature series geometry makes it well suited to tight-tolerance finishing and light roughing passes in small-feature applications. It is centercutting, allowing direct plunge entry, and runs uncoated for broad material compatibility. Machinists and toolroom operators working in CNC machining centers and manual mills select this tool for detail work where corner protection and dimensional accuracy are critical.

This end mill fits into miniature and small-part machining operations typical in mold and die work, medical device manufacturing, aerospace component machining, and general precision shop work. Its 3/16 inch straight-cylindrical shank seats into standard toolholders and collet chucks used across most CNC milling platforms. The 33/64 inch length of cut provides adequate flute engagement for common shallow-pocket and profile operations without excessive tool deflection.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 0.50 mm corner radius protects cutting edges and produces controlled corner breaks on finished parts
• Centercutting design allows direct plunge and ramp entry without pilot drilling
• 4-flute right-hand spiral provides smooth chip evacuation and improved surface finish
• Bright/uncoated finish compatible with a wide range of workpiece materials including aluminum, steel, stainless steel, cast iron, and composites
• Straight-cylindrical 3/16 inch shank fits standard collet chucks and toolholders

Compatibility

Designed for use with standard collet chucks and toolholders accepting a 3/16 inch straight-cylindrical shank. Suitable for milling steel, stainless steel, cast iron, aluminum, non-ferrous metals, wood, and composite workpiece materials.

Installation Notes

Installation and operation of this end mill should be performed by qualified machinists familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is powered down before loading or changing tooling. Seat the shank fully into the toolholder and torque the collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
