Harvey Tool 33225 Square End Mill 0.025 in 3 Flute Carbide

Product Description

The HARVEY TOOL 33225 is a solid carbide square end mill designed for precision milling of tight-tolerance features in a wide range of materials. With a 0.025-inch cutting diameter and a 0.038-inch length of cut, this tool is purpose-built for micro-milling applications where control and edge integrity are critical. The 3-flute geometry with a 30-degree helix angle balances chip evacuation and cutting efficiency at small diameters. The bright uncoated finish suits applications where coating adhesion or thermal interaction must be avoided. Machinist and toolroom professionals working with CNC mills rely on this end mill for fine-detail slotting, profiling, and contouring work.

This end mill is suited to micro-scale machining operations in production shops, toolrooms, and prototype environments. The 0.125-inch shank diameter fits standard collet systems, and the 2.5-inch overall length provides adequate reach without sacrificing rigidity. The extended reach design with a 0.125-inch reach length allows access to features in recessed or stepped workpiece geometry. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle configurations. The centercutting capability allows plunge entry without a pre-drilled start hole.

Key Features

• 0.025-inch cutting diameter for micro-milling and fine-detail work
• 3-flute geometry with 30-degree helix for efficient chip evacuation at small scale
• Solid carbide construction for rigidity and edge retention
• Centercutting design allows direct plunge entry
• Bright uncoated finish suitable for non-ferrous metals, plastics, and other materials sensitive to coatings
• Extended reach with 0.125-inch reach length for recessed feature access

Compatibility

Designed for use in CNC machining centers and manual mills with standard collet systems accepting a 0.125-inch shank diameter.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in a safe, locked-out state. Use a precision collet sized to 0.125 inches for secure clamping and minimal runout. At this diameter, runout tolerance is critical — verify collet and spindle concentricity before cutting. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the specific workpiece material.
