Harvey Tool 936905 Corner Radius End Mill 3mm 4 Flute

Product Description

The HARVEY TOOL 936905 is a miniature corner radius end mill designed for precision milling in tight tolerances. Built from solid carbide with a bright uncoated finish, it features a 3 mm (0.1180 inches) cutting diameter, a 0.0100-inch corner radius, and four right-hand spiral flutes. The stub-length geometry provides rigidity in compact setups. With a 30-degree helix and centercutting capability, this tool handles both roughing and finishing passes in a single operation. It is sized for use in CNC machining centers and toolholders accepting a 0.1250-inch straight cylindrical shank.

This end mill is suited for precision work on steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials. The stub standard length makes it appropriate for shallow-pocket milling, contour work, and detail passes where tool overhang must be minimized. It is commonly used in job shops, tool rooms, and production machining environments where miniature component work demands consistent edge geometry and tight dimensional control. Single-end configuration keeps the tool compact and easy to index in standard toolholders.

Key Features

• 3 mm (0.1180 inches) mill diameter with 0.0100-inch corner radius for controlled edge blending
• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 4-flute right-hand spiral design supports both roughing and finishing in a single pass
• Centercutting geometry allows plunge entry without a pre-drilled hole
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Bright uncoated finish suitable for aluminum, composites, and general-purpose steel milling

Compatibility

Designed for use with standard toolholders accepting a 0.1250-inch straight cylindrical shank. Compatible with CNC machining centers running steel, stainless steel, cast iron, aluminum, non-ferrous metals, wood, and composite workpiece materials per ISO material codes P, M, K, N, and O.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the shank fully in the toolholder collet and torque to the toolholder specification before use. Inspect the corner radius and cutting edges for chips or wear before each use, particularly in high-cycle production runs.
