Harvey Tool 51662 Corner Radius End Mill 0.062 in 4 Flute

Product Description

The HARVEY TOOL 51662 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous materials. With a 0.0620-inch diameter and a 0.50 mm (0.0200-inch) corner radius, this miniature tool is built for tight-tolerance profiling and finishing passes where edge integrity matters. The 4-flute, right-hand spiral configuration supports both roughing and finishing operations in a single tool. At 0.01 pounds, the 51662 is a compact, single-end, centercutting tool suited for CNC machinists and toolroom operators working in miniature-scale applications.

This end mill is intended for use in steel, stainless steel, cast iron, aluminum, non-ferrous metals, composites, and wood. Its stub and standard miniature profile makes it well suited for small-feature machining on vertical machining centers and CNC mills. The bright uncoated finish means it can be run as-is or used where specific coatings are not required or may interfere with workpiece material. Typical applications include slot milling, profiling, and corner radius blending on precision components in aerospace, medical, and general machining environments.

Key Features

• 0.0620-inch mill diameter with corner radius tolerance of plus or minus 0.0010 inch
• 0.50 mm (0.0200-inch) corner radius for consistent edge blending and reduced stress concentration
• 4-flute solid carbide construction supports roughing and finishing in a single pass
• Centercutting geometry allows plunge entry into workpiece material
• Right-hand cut, right-hand spiral flute direction for standard CNC spindle compatibility
• Bright uncoated finish suitable for a broad range of workpiece materials including aluminum and composites
• No coolant-through — designed for external coolant or dry machining setups

Compatibility

Designed for use with standard toolholders accepting a 0.1250-inch straight cylindrical shank. Part of the HARVEY TOOL Miniature End Mills Corner Radius Stub and Standard series.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Secure the 0.1250-inch shank in a compatible collet or end mill holder and verify runout before cutting. Confirm spindle speed and feed rate are appropriate for the workpiece material and tool diameter before engaging the cut. Do not exceed the 0.1860-inch length of cut; overextension beyond this depth risks deflection and tool breakage at this miniature diameter.
