Harvey Tool 33308-C3 Square End Mill 0.125 in 3 Flute Altin

Product Description

The HARVEY TOOL 33308-C3 is a solid carbide square end mill designed for precision milling in demanding machining applications. It features a 0.125-inch (1/8 inch) cutting diameter, a 0.1875-inch (3/16 inch) length of cut, and a 30-degree helix angle. The three-flute geometry balances chip evacuation with cutting efficiency, making it well suited for finishing passes and slotting in harder materials. An AlTiN coating provides elevated heat resistance and surface hardness, extending tool life in high-temperature cutting conditions. The centercutting design allows plunge entry, adding versatility to the tool's application range.

This end mill is intended for use in CNC machining centers and manual mills where tight tolerances and fine surface finishes are required. The extended reach configuration, with a 0.625-inch reach length and 2.5-inch overall length on a 0.125-inch shank, accommodates work in deeper pockets or recessed features. Right-hand cut and right-hand flute geometry match standard spindle rotation on most vertical and horizontal machining centers. It is typically installed and used by machinists, toolmakers, and CNC operators working in job shops, production facilities, or maintenance environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hardened and abrasive materials
• AlTiN coating for improved heat resistance and extended tool life at elevated cutting speeds
• 3-flute design balances chip clearance and surface finish quality
• 30-degree helix angle promotes smooth cutting action and reduced chatter
• Centercutting capability allows direct plunge entry without a pre-drilled pilot hole
• Extended reach with 0.625-inch reach length for access to deeper features

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for use in standard 1/8-inch collets and tool holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Use a calibrated torque wrench and the appropriate collet or end mill holder rated for 0.125-inch shank tooling. Verify runout with a dial indicator after tool installation before beginning any cutting operation.
