Accupro 12465802 Ball End Mill 0.0350 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12465802 is a miniature solid carbide ball end mill designed for precision milling operations in tight geometries and small-feature work. At 0.0350 inches in diameter with a 0.0520-inch length of cut and four flutes, it delivers fine surface finishes and accurate contour profiles in hardened steels, stainless alloys, and non-ferrous materials. The AlTiN coating provides high heat resistance and extended tool life in demanding cutting conditions. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This tool is installed and operated by machinists and CNC programmers working in tool-and-die, mold-making, medical device, and aerospace precision machining environments.

The 12465802 fits applications requiring miniature ball end milling, including finishing of small radii, blending of complex 3D surfaces, and profiling of intricate mold cavities. The single-end configuration, 1/8-inch shank diameter, and 1-1/2-inch overall length make it compatible with standard ER collet systems and small-diameter tool holders commonly used on vertical machining centers and high-speed CNC mills. Micrograin carbide grade ensures rigidity and edge retention in fine-pitch cuts.

Key Features

• 0.0350-inch ball diameter for small-radius and fine-feature milling
• AlTiN coating for high-temperature resistance and extended tool life
• 4-flute spiral geometry with 30-degree right-hand helix for efficient chip removal
• Micrograin solid carbide substrate for edge sharpness and rigidity
• 1/8-inch shank diameter fits standard ER collets and small-bore tool holders
• Single-end, right-hand cut configuration for standard CNC spindle use

Compatibility

Designed as a miniature series solid carbide ball end mill for use in standard ER collet holders and tool holders accepting a 1/8-inch shank diameter on CNC vertical machining centers and high-speed milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet holder. Use a properly sized ER collet matched to the 1/8-inch shank and torque the collet nut to the tool holder manufacturer specification. Due to the miniature diameter, verify runout with a dial indicator before initiating cuts, as excessive runout will cause premature tool breakage.
