Harvey Tool 33709 Square End Mill 9/64 in 4 Flute Carbide

Product Description

The HARVEY TOOL 33709 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 9/64 inch (0.1406 inch) cutting diameter and four flutes, this end mill delivers clean, accurate cuts in ferrous and non-ferrous materials. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Its bright, uncoated finish makes it well-suited for use with aluminum, brass, and other non-ferrous materials where coating adhesion is not required. Licensed machinists and CNC operators typically select this tool for finish milling, slotting, and profiling passes where tight dimensional tolerances are critical.

This end mill is built for use in CNC machining centers, vertical mills, and manual milling machines where a small-diameter, long-reach cutting tool is needed. The 1-1/8 inch length of cut and 3/16 inch shank diameter make it practical for milling in confined pockets and narrow slots. Its centercutting geometry allows plunge entry directly into the workpiece, adding flexibility to the toolpath strategy. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• 9/64 inch (0.1406 inch) cutting diameter with 1-1/8 inch length of cut
• 4-flute design for improved surface finish and material removal balance
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry into the workpiece
• Bright, uncoated finish suited for non-ferrous and non-abrasive materials
• Right-hand cut, right-hand flute with fixed helix — no variable geometry

Compatibility

Designed as a standard solid carbide square end mill for use in CNC machining centers and manual milling machines that accept a 3/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and locked out before installing or removing any cutting tool. Use a properly sized collet or end mill holder rated for a 3/16 inch shank; verify runout with a dial indicator before production cutting. Follow the tool manufacturer and machine tool builder recommendations for feeds, speeds, and depth of cut to avoid tool breakage.
