Accupro 12184066 Ball End Mill 0.039 in 2 Flute Carbide

Product Description

The ACCUPRO 12184066 is a solid carbide ball end mill designed for precision milling of complex contours, curved surfaces, and 3D profiles in ferrous and non-ferrous materials. With a 0.039 inch (1.00 mm) mill diameter and a 40-degree helix angle, this stub-length tool delivers accurate material removal in tight geometries. The AlTiN coating provides thermal resistance and extended tool life when cutting harder workpiece materials. It is a single-end, right-hand cutting tool intended for use on CNC machining centers and milling machines by machinists and tool-and-die professionals.

This end mill is suited for small-feature finish milling and die work requiring fine detail. The 0.0787 inch (2.00 mm) length of cut, 3.00 mm shank diameter, and 38.00 mm overall length make it appropriate for applications where stub reach and rigidity are priorities. It is a common choice in mold making, aerospace component finishing, and precision part production where minimal deflection is critical.

Key Features

• 0.039 inch (1.00 mm) ball nose diameter for fine-detail contour milling
• Micrograin solid carbide construction for hardness and wear resistance
• AlTiN coating for elevated heat resistance in hard-material applications
• 40-degree helix angle promotes smooth chip evacuation and surface finish
• Stub-length design reduces deflection in high-precision cuts
• Right-hand cut, right-hand spiral flute geometry for standard CNC spindle use

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for CNC machining centers accepting a 3.00 mm round shank. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and powered down before inserting or removing the tool from the holder. Use a collet or tool holder rated for the 3.00 mm shank diameter and confirm runout is within acceptable tolerance for the application before starting a cut. At this diameter, excessive side load or interrupted cuts can result in tool breakage.
