Accupro 12185344 Ball End Mill 0.1406in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185344 is a double-end ball end mill designed for precision milling operations in metalworking and machining applications. Built from solid carbide with a TiCN (titanium carbonitride) coating, it delivers extended tool life and wear resistance in ferrous and non-ferrous materials. The 0.1406-inch (9/64-inch) cutting diameter and 4-flute spiral geometry support efficient chip evacuation and smooth surface finishes in tight-tolerance work. At 2 inches overall length with a 0.3125-inch length of cut, this stub-length tool provides rigidity in setups where deflection must be minimized. The 40-degree helix angle balances cutting force and material removal rate across a range of workpiece materials.

This end mill is suited for CNC machining centers and manual mills performing profiling, contouring, slotting, and finish passes in die and mold work, aerospace components, and precision part manufacturing. The double-end configuration provides two usable cutting ends, extending the service interval before replacement. Right-hand cut and right-hand flute direction make it compatible with standard spindle setups. Machinists working with hardened steels, stainless, cast iron, and high-temp alloys will find the TiCN coating particularly effective at reducing built-up edge and heat-related wear.

Key Features

• Solid carbide construction for rigidity and heat resistance in demanding cuts
• TiCN coating improves hardness and reduces friction at the cutting edge
• 4-flute spiral design supports efficient chip flow and fine surface finish
• 40-degree helix angle balances cutting forces across a range of materials
• Double-end design provides two cutting ends per tool
• Stub length of cut (0.3125 inches) maximizes rigidity and reduces deflection

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill for standard CNC and manual milling setups accepting a 3/16-inch shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and at rest before changing tooling. Secure the 3/16-inch shank in a collet or end mill holder rated for the shank diameter, verified to appropriate runout tolerance for the application. Follow shop-standard speeds and feeds for the workpiece material and coating type; do not exceed the tool's rated cutting diameter or depth of cut without engineering review.
