Accupro 12185340 Ball End Mill 0.125 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185340 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.125-inch mill diameter, 4-flute geometry, and a 40-degree helix angle, this end mill delivers smooth chip evacuation and consistent surface finishes in tight-tolerance applications. It is configured as a double-end tool, effectively extending usable tool life. The stub-length profile and right-hand cutting and flute direction make it well suited for CNC machining centers and manual mills where rigidity and dimensional accuracy are critical. Machinists and tool-and-die professionals are the primary installers and users of this tooling.

This end mill is appropriate for finishing and semi-finishing passes in mold-making, die work, contour milling, and slot milling applications. The 0.25-inch length of cut suits shallow-depth profiling and detail work. The 0.125-inch shank diameter is a standard collet size compatible with ER-style and precision collet toolholding systems commonly found in production and job-shop environments. The 1.5-inch overall length supports use in standard toolholding without requiring extended-reach configurations.

Key Features

• 0.125-inch mill diameter with matching 0.125-inch shank for direct collet mounting
• 4-flute spiral configuration for improved surface finish and feed rate capability
• 40-degree right-hand helix angle promotes efficient chip evacuation
• Double-end design provides two usable cutting ends per tool
• Solid carbide construction delivers hardness and wear resistance in demanding cuts
• Uncoated finish suitable for applications where coating is not required or where regrinding is anticipated

Compatibility

Designed as an OEM-style replacement and standard production tool for CNC machining centers and manual mills using 0.125-inch collet or toolholding systems.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC or manual milling equipment. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify collet size and runout tolerance before securing the shank. Do not exceed the rated depth of cut or feed rate for the workpiece material and machine rigidity.
