Accupro 12185364 Ball End Mill 0.2344in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185364 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hardened material applications. With a 0.2344-inch mill diameter and a 4-flute spiral geometry, it delivers smooth cutting action and efficient chip evacuation in both roughing and finishing passes. The 40-degree helix angle reduces cutting forces and improves surface finish at the workpiece. Built as a double-end tool, it extends usable tool life before replacement is needed. This end mill is suited for CNC machining centers and manual mills operated by machinists and tooling professionals in production and job shop environments.

This end mill is well suited for contouring, slotting, and profile milling in tight-tolerance work. The 0.5-inch length of cut and 0.25-inch shank diameter make it appropriate for moderate-depth passes in ferrous and non-ferrous materials. The stub-length classification keeps the tool rigid and minimizes deflection during aggressive cuts. Right-hand cutting and right-hand flute direction match standard CNC spindle rotation without modification. The 2.5-inch overall length allows straightforward toolholder engagement with standard ER or end mill holders.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• Ball end geometry for contour milling, profiling, and 3D surface work
• 4-flute spiral design promotes efficient chip evacuation and smooth finish
• 40-degree helix angle reduces cutting forces and improves surface quality
• Double-end configuration extends tool service life before replacement
• Uncoated finish suitable for use with cutting fluid or dry in appropriate materials

Compatibility

Designed as an OEM-style solid carbide ball end mill compatible with standard 0.25-inch bore end mill holders, ER collet chucks, and similar toolholding systems used on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder torque requirements and runout inspection procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the toolholder to the minimum engagement depth recommended by the holder manufacturer. Inspect the cutting edges for chips or damage before each use and verify runout with a dial indicator after installation.
