Harvey Tool 941150 Corner Radius End Mill 1/4 in 4 Fl

Product Description

The HARVEY TOOL 941150 is a solid carbide corner radius end mill designed for precision milling in a wide range of metalworking and machining applications. With a 1/4-inch mill diameter, a 0.05-inch corner radius, and 4 helical flutes in a right-hand cutting direction, this tool delivers both roughing and finishing capability in a single-end, stub-length configuration. The overall length is 2.5 inches with a 3/8-inch length of cut. The bright, uncoated finish suits shops that prefer re-coating or are running compatible cutting fluids directly. A licensed machinist or CNC tooling technician is the typical installer for this class of cutting tool.

This end mill fits standard toolholders accepting a 1/4-inch straight cylindrical shank and is suited for milling steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials. The stub-length design improves rigidity and reduces deflection in tight-clearance or high-precision setups. It is well-suited for production environments running vertical machining centers, CNC routers, or manual mills where a corner radius profile is required to reduce stress concentrations in milled pockets and slots.

Key Features

• 0.05-inch corner radius with tolerance of plus or minus 0.001 inch for consistent edge geometry
• Solid carbide construction for rigidity and wear resistance across ferrous and non-ferrous materials
• 4 helical flutes with right-hand cutting direction support efficient chip evacuation
• Center-cutting design allows direct plunge entry without pre-drilling
• Stub-length configuration minimizes overhang and deflection in precision applications
• Uncoated bright finish compatible with re-coating or standard cutting fluid use

Compatibility

Designed for use with standard toolholders accepting a 1/4-inch straight cylindrical shank. Compatible with CNC machining centers, manual mills, and CNC routers equipped for that shank size.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully powered down and locked out before inserting or removing the tool from the toolholder. Verify runout with a dial indicator before beginning a production run. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.
