Harvey Tool 956908-C3 Square End Mill 0.125in 4 Flute Carbide

Product Description

The HARVEY TOOL 956908-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.125 inch cutting diameter, 0.375 inch length of cut, and a 4-flute geometry with a 30-degree helix angle, this tool delivers smooth chip evacuation and stable cutting performance in ferrous and non-ferrous materials. The AlTiN coating provides elevated heat resistance and extended tool life at higher cutting speeds. Right-hand cut and right-hand flute orientation are standard. This end mill is selected and installed by machinists and CNC programmers running production or prototype milling operations.

This end mill is suited for slot milling, profiling, and finishing passes in tight-tolerance applications. The 0.125 inch shank diameter matches the cutting diameter, and the 0.625 inch reach length and 1.5 inch overall length make it appropriate for shallow-to-moderate depth features. Extended reach geometry allows access to recessed walls or pocketed areas without sacrificing rigidity at this diameter. Compatible with standard 1/8 inch collet systems on CNC vertical machining centers and high-speed spindles.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for high-temperature performance and extended tool life
• 30-degree helix angle promotes efficient chip evacuation
• 4-flute design balances material removal rate with surface finish quality
• Center-cutting capable - suitable for plunge entry
• Extended reach geometry for access to recessed features

Compatibility

Designed for use with standard 1/8 inch collet chucks and ER-style collet systems on CNC machining centers. Verify spindle collet size and runout specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before tool changes. Use a properly sized collet and torque the collet nut according to the toolholder manufacturer specifications. Confirm tool runout with a dial indicator after clamping, particularly at this diameter, as runout sensitivity is high in small-diameter end mills.
