Accupro 12184364 Ball End Mill 0.3281 in 3 Flute Carbide

Product Description

The ACCUPRO 12184364 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and engineered material applications. Featuring a 0.3281-inch (21/64) cutting diameter and three flutes, this single-end tool delivers efficient chip evacuation and smooth finish cuts in contoured and profiled surfaces. The 40-degree helix angle promotes aggressive cutting action while reducing chatter. Micrograin carbide construction provides the hardness and wear resistance required for demanding cuts in ferrous and non-ferrous materials. This tool is used by machinists and tool-and-die professionals working on CNC machining centers and manual mills.

This ball end mill is well suited for 3D profiling, slotting, and contour milling in production and job-shop environments. The 0.875-inch length of cut allows access into moderate-depth pockets and curved surfaces. With a 3/8-inch shank diameter and 2.5-inch overall length, it fits standard ER and side-lock collet systems commonly found on vertical machining centers. The uncoated finish makes it a reliable choice for use with cutting fluids on aluminum, steel, and similar materials where coating adhesion is not required.

Key Features

• 0.3281-inch (21/64) ball nose cutting diameter for accurate radius profiling
• Three-flute spiral geometry with 40-degree right-hand helix for efficient chip flow
• Micrograin solid carbide construction for hardness and extended tool life
• 0.875-inch length of cut supports moderate-depth pocket and contour work
• Single-end design with 3/8-inch shank for broad collet compatibility
• Uncoated finish compatible with flood and mist coolant strategies

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC vertical machining centers and manual mills accepting a 3/8-inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling procedures. Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before inserting or removing the tool. Use a calibrated torque wrench and appropriate collet nut wrench when seating the shank in an ER collet chuck to achieve proper clamping force. Confirm runout with a dial indicator before beginning production cuts.
