Harvey Tool 50309-C3 Square End Mill 9/64 in 4 Flute Altin

Product Description

The HARVEY TOOL 50309-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 9/64 inch (0.1406 inch) cutting diameter and a 7/32 inch (0.2200 inch) length of cut, this tool handles slotting, profiling, and finishing passes in tight spaces. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. An AlTiN coating extends tool life in abrasive and high-temperature applications. The single-end, right-hand cutting configuration is standard for CNC vertical and horizontal machining centers. Machinists and tool-and-die professionals use this style of end mill for close-tolerance work in ferrous and non-ferrous materials.

This end mill fits applications where small-diameter tooling is required, including mold and die work, aerospace components, and precision mechanical parts. The 3/16 inch shank diameter suits standard collet chucks and end mill holders found on most CNC machining centers and manual knee mills. The 2 inch overall length keeps the tool rigid at this diameter, minimizing deflection during full-depth cuts. It is appropriate for job shops and production environments where consistent, repeatable results are required on small features and fine detail work.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating improves heat resistance and extends tool life in abrasive materials
• 4-flute design provides a balance of chip clearance and surface finish quality
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Center-cutting capable, allowing plunge entry into the workpiece
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill suitable for standard 3/16 inch collet chucks and end mill holders on CNC machining centers and compatible milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the collet or tool holder and torque the drawbar or collet nut to the machine manufacturer's specification. Inspect the cutting edges for chips or damage before each use, and verify runout with a dial indicator when tight tolerances are required.
