Accupro 12184679 Ball End Mill 0.4844 in 4 Flute Carbide

Product Description

The ACCUPRO 12184679 is a single-end ball end mill designed for precision milling of contoured surfaces, 3D profiles, and radius features in metalworking applications. Manufactured from micrograin solid carbide, it delivers the rigidity and edge retention required for demanding cuts in steel, cast iron, and similar materials. The tool measures 0.4844 inches in diameter with a 1-inch length of cut, a 1/2-inch shank diameter, and a 3-inch overall length. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is well suited for CNC machining centers and manual mills operated by machinists and toolroom professionals.

This ball end mill is intended for finishing and semi-finishing operations on complex 3D surfaces in job shops, production machining environments, and toolroom settings. The ball nose geometry generates consistent radii on contoured workpieces, making it a common choice for die and mold work, aerospace components, and general precision parts. The uncoated micrograin carbide construction performs well in both dry and flood-cooled cutting conditions.

Key Features

• Solid micrograin carbide construction for high edge retention and wear resistance
• 40-degree right-hand helix promotes efficient chip flow and reduces chatter
• 4-flute design balances material removal rate with surface finish quality
• Ball nose geometry generates accurate radii on 3D contoured surfaces
• Single-end configuration with a true 0.4844-inch diameter and tight tolerance control
• Uncoated finish suitable for a wide range of ferrous and non-ferrous materials

Compatibility

Designed as a standard shank ball end mill for use in CNC machining centers and manual knee mills accepting a 1/2-inch collet or end mill holder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and locked before inserting or removing the tool. Seat the shank fully in a clean, properly sized collet or end mill holder and torque the retention nut to the tool holder manufacturer's specification. Inspect the cutting edges for chips or damage before each use, as carbide tools are brittle and should not be forced into interrupted cuts beyond their rated capacity.
