Harvey Tool 12775-C3 Square End Mill 0.075 in 3 Flute Carbide

Product Description

The HARVEY TOOL 12775-C3 is a solid carbide square end mill designed for precision milling in demanding machining applications. With a 0.075-inch cutting diameter, 3-flute spiral configuration, and a 30-degree helix angle, this tool delivers clean, accurate cuts in ferrous and non-ferrous materials. The AlTiN coating improves heat resistance and extends tool life in high-speed cutting environments. The micrograin carbide substrate provides edge retention where standard carbide falls short. This tool is installed and operated by machinists, CNC operators, and toolroom technicians working with vertical and horizontal milling machines or machining centers.

This end mill is suited for slot milling, profiling, and plunge cutting in applications requiring a small-diameter, long-reach tool. The 0.5-inch length of cut paired with a 2.5-inch overall length makes it a practical choice for accessing deeper features or pockets in workpieces where clearance is limited. The centercutting geometry allows direct plunge entry without a pre-drilled hole. Right-hand cut and right-hand flute direction conform to standard spindle rotation for most CNC and manual milling setups.

Key Features

• 0.075-inch cutting diameter with micrograin solid carbide construction for edge stability at small diameters
• AlTiN finish provides oxidation resistance and thermal hardness for extended tool life in abrasive materials
• 3-flute, 30-degree spiral helix balances chip evacuation with cutting edge strength
• Centercutting design enables direct plunge milling without pilot drilling
• Long-reach configuration with 0.5-inch LOC and 2.5-inch OAL for deep-pocket and restricted-clearance work
• Right-hand cut, right-hand flute — compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style precision cutting tool for use in CNC machining centers, vertical mills, and manual milling machines that accept a 0.125-inch shank diameter collet or tool holder.

Installation Notes

This end mill is installed by qualified machinists or CNC operators using an appropriate collet or tool holder sized for a 0.125-inch shank. Ensure the spindle and tool holder are clean and free of debris before seating the tool, and verify runout with a dial indicator prior to production cuts. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material and coating type. Always power down and lock out the machine before changing tooling.
