Accupro 12184367 Ball End Mill 0.3438 in 3 Flute Carbide

Product Description

The ACCUPRO 12184367 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.3438-inch (11/32-inch) cutting diameter and a 0.875-inch length of cut, this single-end tool delivers accurate contoured and profiled cuts in a compact form factor. The 3-flute geometry paired with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Constructed from micrograin solid carbide, the tool offers rigidity and wear resistance suited to demanding milling work. The uncoated finish makes it well suited for non-ferrous metals and general-purpose machining where coating is not required.

This ball end mill is used in CNC machining centers and manual milling machines for 3D contouring, slotting, profiling, and finishing passes in dies, molds, and precision components. The right-hand cutting and right-hand spiral flute direction are standard for conventional CNC spindle setups. At 2.5 inches overall length with a 3/8-inch straight shank, this tool fits standard collet and end mill holders used in typical shop environments. It is appropriate for residential machine shops, toolrooms, and production floors handling precision metalwork.

Compatibility

Designed as a replacement-style solid carbide ball end mill for use in standard CNC machining centers and manual mills accepting a 3/8-inch straight shank with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Always power down and lock out the spindle before changing tooling. Ensure the shank is clean and fully seated in the collet or tool holder to the recommended engagement depth before tightening. Do not exceed the tool manufacturer recommended feeds and speeds for the workpiece material and machine setup.
