Harvey Tool 941110-C3 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The HARVEY TOOL 941110-C3 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous materials. It features a 1/4 inch mill diameter, a 0.01 inch corner radius, and four helical flutes ground for both roughing and finishing operations. The AlTiN PVD coating improves heat resistance and tool life in steel, stainless steel, cast iron, and non-ferrous metals. With a 3/8 inch length of cut and a 2-1/2 inch overall length, this is a short-reach, stub-geometry tool suited for rigid setups in CNC machining centers. It is installed by machinists and CNC operators working in precision metalworking environments.

This end mill belongs to the Harvey Tool Miniature End Mills - Corner Radius - Stub and Standard series. It is suited for light-to-moderate material removal in steel, stainless steel, cast iron, and non-ferrous and composite materials. The stub length geometry reduces deflection and improves stability in tight clearance applications. The 1/4 inch straight cylindrical shank fits standard toolholders used in CNC milling operations across job shops, aerospace, and general machining environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN PVD coating for improved heat resistance and extended tool life
• 0.01 inch corner radius reduces stress concentrations and extends part life at machined edges
• Four right-hand helical flutes support both roughing and finishing in a single tool
• Center-cutting capable for plunge entry without a pre-drilled hole
• Stub length geometry minimizes deflection in rigid, close-tolerance setups

Compatibility

Designed for use with standard straight-bore toolholders accepting a 1/4 inch cylindrical shank. Compatible with CNC milling machines running right-hand cutting direction. Suitable for workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and composites.

Installation Notes

Installation is performed by a machinist or CNC operator. The machine spindle must be fully stopped and the toolholder released before changing cutting tools. Confirm the toolholder bore is clean and free of chips before seating the shank to maintain runout tolerances. Do not exceed the tool manufacturer's recommended feeds and speeds for the specified workpiece material and coating type.
