Accupro 12184792 Ball End Mill 19/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12184792 is a single-end ball end mill designed for precision contouring, profiling, and 3D machining operations in ferrous and non-ferrous materials. Built from micrograin solid carbide, it offers the rigidity and wear resistance needed for high-speed cutting applications. The 19/64-inch (0.2969 inch) cutting diameter pairs with a 1/2-inch length of cut and a 40-degree helix angle that promotes aggressive chip evacuation and reduces chatter. An AlTiN coating adds thermal and oxidation resistance, extending tool life in dry or semi-dry cutting conditions. Machinists and CNC operators in job shops, tool rooms, and production environments will find this end mill suited to demanding finishing and semi-finishing passes.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where a ball-nose profile is required for curved surface work, die and mold contouring, or slotting with a radiused floor. The right-hand cutting and right-hand spiral flute geometry is standard for conventional spindle setups. The stub-length classification means the tool prioritizes rigidity over reach, making it well-suited for shallow-to-medium depth features where deflection control is critical.

Key Features

• Micrograin solid carbide construction for high hardness and edge retention
• AlTiN coating provides oxidation resistance and extended tool life in dry cutting
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• 4-flute configuration balances material removal rate with surface finish quality
• Stub-length body maximizes rigidity and minimizes deflection in the cut
• Single-end ball nose profile for 3D contouring, profiling, and radiused floor features

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5/16-inch straight shank end mill holder, collet chuck, or shrink-fit toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and locked out before tool changes. Secure the 5/16-inch shank to the appropriate holding system to the depth recommended by the toolholder manufacturer, ensuring adequate grip length to prevent pullout under load. Inspect the collet or end mill holder for wear or contamination before seating the tool. Always verify runout with a dial indicator after tool installation and before initiating a cutting program.
