Accupro 12184820 Ball End Mill 13/32 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12184820 is a solid carbide ball end mill designed for precision milling operations in metal fabrication and machining. It features a 13/32 inch (0.4063 inch) cutting diameter, a 5/8 inch length of cut, and a 4-flute spiral configuration with a 40-degree helix angle. The micrograin carbide construction delivers the hardness and edge retention required for contouring, profiling, and 3D surface work in ferrous and non-ferrous materials. This is a single-end, right-hand cutting tool with a bright uncoated finish, suited for machinists and tool-and-die professionals running standard and CNC milling equipment.

This ball end mill is appropriate for stub-length milling applications where rigidity and minimal tool deflection are priorities. The 7/16 inch shank diameter is compatible with standard ER collet chucks and end mill holders. The uncoated bright finish makes it a cost-effective choice for general-purpose milling in aluminum, mild steel, and similar materials where high-temperature coatings are not required. It is well suited to production shops and job shops performing contour milling, die work, and finish passes on machining centers.

Key Features

• Solid micrograin carbide construction for improved wear resistance and edge integrity
• 40-degree right-hand helix promotes efficient chip evacuation during milling
• 4-flute spiral design balances surface finish quality with material removal rate
• Ball end geometry enables contouring, radii, and 3D profiling cuts
• Stub length provides added rigidity and reduced deflection in tight setups
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fitment

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC and manual milling machines accepting a 7/16 inch shank diameter end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the collet or holder to prevent pullout under cutting loads. Verify runout with a dial indicator before beginning production cuts.
