Accupro 12185342 Ball End Mill 0.125in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185342 is a double-end ball end mill designed for precision milling operations in metal and alloy workpieces. Built from solid carbide, it delivers the rigidity and wear resistance required for demanding cutting environments. The 0.125-inch diameter cutting profile and 4-flute geometry work together to produce smooth surface finishes in contoured and 3D profiling applications. An AlTiN coating provides high heat resistance and extended tool life, particularly when cutting hardened steels, stainless, and high-temperature alloys. The double-end configuration maximizes value by providing two usable cutting ends per tool.

This end mill is suited for CNC machining centers and vertical mills used in tool-and-die, mold making, aerospace component work, and precision job-shop environments. The stub length classification and 0.25-inch length of cut make it appropriate for shallow-depth profiling, slot milling, and finish passes where rigidity and minimal deflection are priorities. The right-hand cut and right-hand spiral flute direction are standard for conventional CNC spindle configurations.

Key Features

• Solid carbide construction for maximum rigidity and tool life in hard materials
• AlTiN coating for elevated heat resistance and reduced friction during high-speed cutting
• 4-flute design balances chip evacuation with surface finish quality
• Double-end configuration provides two cutting ends per tool
• 40-degree helix angle promotes smooth cutting action and improved finish
• Right-hand cut and right-hand flute spiral compatible with standard CNC spindle direction

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard CNC machining centers and manual mills accepting a 0.125-inch shank diameter collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or end mill holder rated for the 0.125-inch shank diameter to prevent runout and tool pullout. Follow machine tool manufacturer guidelines for speed, feed, and depth-of-cut recommendations when setting up cutting parameters.
