Harvey Tool 823100-C3 Square End Mill 0.1in 3 Flute

Product Description

The HARVEY TOOL 823100-C3 is a solid carbide square end mill designed for precision milling operations in demanding shop environments. With a 0.1 inch cutting diameter and a 0.15 inch length of cut, this tool is built for finishing and light profiling passes where tight tolerances are required. The AlTiN coating increases surface hardness and heat resistance, making it well-suited for dry cutting and elevated-temperature applications. Three flutes provide a balance between chip evacuation and wall finish quality. This tool is used by machinists and tool-and-die professionals working with ferrous and hardened materials.

This end mill is appropriate for CNC milling centers and manual knee mills handling small-feature work in steel, stainless steel, titanium, and high-temperature alloys. The 30-degree helix angle promotes smooth cutting action and reduces chatter on shallow pockets and contour passes. With a 0.125 inch shank diameter and 1.5 inch overall length, it fits standard collets and end mill holders used in both production and prototype environments. Right-hand cutting and right-hand flute direction are standard for conventional milling setups.

Key Features

• 0.1 inch cutting diameter for fine-feature and small-bore milling
• AlTiN coating for improved heat resistance and extended tool life in ferrous materials
• 3 flutes for efficient chip evacuation and quality wall finish
• 30-degree helix angle reduces cutting forces and chatter
• Center-cutting geometry allows direct plunge entry
• Solid carbide construction for rigidity and wear resistance

Compatibility

Designed as an OEM-style replacement-grade solid carbide square end mill suitable for standard 1/8 inch collets and end mill holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Use a calibrated collet or end mill holder torqued per the holder manufacturer specification and confirm runout with a dial indicator before cutting. Follow applicable shop safety standards and machine tool manufacturer guidelines for tool clamping procedures.
