Accupro 12185328 Ball End Mill 0.0469 in 4 Flute Carbide

Product Description

The ACCUPRO 12185328 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. At 0.0469 inches (3/64 inches) in diameter with a 0.0938 inches (3/32 inches) length of cut, this tool is built for tight-tolerance work in confined geometries, slots, and contoured surfaces. The 4-flute configuration supports efficient chip evacuation while maintaining surface finish quality. A 40-degree helix angle improves cutting performance across a range of workpiece materials. This is a double-end tool, providing two usable cutting ends and extending overall service life. It is used by CNC machinists, tool and die makers, and precision machining professionals.

This end mill is suited for milling operations requiring small-diameter tooling in ferrous and non-ferrous materials. The stub length profile and 1/8 inch shank diameter make it compatible with standard collets and tool holders used in CNC machining centers and manual mills. The uncoated solid carbide construction performs well in applications where coating is not required or where re-sharpening is anticipated. Typical applications include mold and die work, aerospace component machining, and general precision part production.

Key Features

• 0.0469 inch (3/64 inch) ball nose diameter for small-feature and contour milling
• 4-flute design balances chip clearance and surface finish performance
• 40-degree helix angle for improved cutting efficiency
• Double-end configuration extends usable tool life
• Solid carbide construction provides rigidity and wear resistance
• Stub length profile (0.0938 inches LOC) minimizes deflection in tight setups

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 1/8 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 powered down before changing tooling. Seat the 1/8 inch shank fully in the collet or tool holder and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator before initiating a cutting program, as excessive runout at this diameter will accelerate tool wear and compromise surface finish.
