Harvey Tool 33230-C3 Square End Mill 0.0300 in 3 Flute Carbide

Product Description

The HARVEY TOOL 33230-C3 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.0300-inch cutting diameter and a 0.045-inch length of cut, this micro end mill is built for fine detail work where rigidity and accuracy are critical. The AlTiN coating improves heat resistance and tool life in ferrous and hard materials. A 30-degree helix angle promotes efficient chip evacuation while reducing cutting forces. Three flutes provide a balance of chip clearance and surface finish quality. This tool is installed and operated by machinists and tooling professionals on CNC machining centers and manual mills.

The 33230-C3 is suited for micro-milling operations in mold making, medical device manufacturing, aerospace components, and precision instrument production. The extended reach design, with a 0.156-inch reach length and a 0.125-inch shank diameter, allows access to features in recessed or hard-to-reach geometries. It is appropriate for use in materials including hardened steels, stainless steels, and non-ferrous alloys where the AlTiN coating provides a thermal and wear barrier.

Key Features

• 0.0300-inch cutting diameter for micro and fine-detail milling
• AlTiN coating for elevated heat resistance and extended tool life
• 30-degree helix angle for efficient chip evacuation and reduced cutting forces
• 3-flute geometry balances chip clearance with surface finish quality
• Extended reach design with 0.156-inch reach length for recessed feature access
• Center-cutting capable, allowing plunge entry
• Right-hand cut, right-hand flute configuration for standard CNC spindle operation

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for use in CNC machining centers and manual mills accepting a 0.125-inch shank diameter collet or toolholder.

Installation Notes

This end mill is installed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or toolholder rated for the 0.125-inch shank to maintain concentricity and prevent runout. At micro diameters, even small amounts of runout can cause premature breakage, so verify toolholder condition and collet cleanliness before installation.
