Accupro 12184136 Ball End Mill 0.2813 in 2 Flute Carbide

Product Description

The ACCUPRO 12184136 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.2813-inch mill diameter and a 2-flute, single-end configuration, this tool delivers accurate contour milling, profiling, and finishing cuts. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides hardness and wear resistance suited for demanding shop environments. The uncoated finish makes this end mill well-suited for applications where coolant is used and coating buildup is a concern. Licensed machinists and CNC operators install this type of tooling in vertical machining centers and manual knee mills.

This stub-length ball end mill is suited for general-purpose contouring, slotting, and finishing in tight-clearance setups where a shorter reach reduces deflection. The 0.5-inch length of cut and 2.0-inch overall length make it practical for shallow-pocket work and curved-surface finishing. It is used in job shops, production machine shops, tooling rooms, and maintenance environments working with steel, aluminum, brass, and similar machinable materials. Right-hand cutting and right-hand flute direction are standard for conventional CNC mill spindle rotation.

Key Features

• 0.2813-inch (9/32 inch) ball nose diameter for contour and radius milling
• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle promotes chip flow and reduces cutting forces
• 2-flute, single-end design balances chip clearance with surface finish capability
• Uncoated finish suitable for use with cutting fluids on a wide range of materials
• Stub length reduces tool deflection in shallow-pocket applications

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC vertical machining centers and manual mills using a 5/16-inch tool holder or collet. No specific compatible machine models were stated in the product data.

Installation Notes

Installation requires a 5/16-inch precision collet, end mill holder, or shrink-fit holder. Verify runout with a dial indicator after seating the tool before beginning a cut. Always stop the spindle and confirm the tool is fully secured before adjusting reach or re-tightening the holder. Follow your machine tool manufacturer guidelines and shop safety protocols when handling carbide tooling.
