Accupro 12184641 Ball End Mill 0.3438 in 4 Flute Carbide Ticn

Product Description

The ACCUPRO 12184641 is a single-end ball end mill designed for precision milling operations in metal and hard-material applications. Built from micrograin solid carbide, it offers the rigidity and edge retention needed for demanding cuts. The cutting diameter measures 0.3438 inches with a 0.875-inch length of cut, making it well suited for profiling, contouring, and finishing work in confined areas. A TiCN coating reduces friction and heat buildup at the cutting edge, extending tool life in ferrous and non-ferrous materials. With a 40-degree helix angle and four flutes, it delivers smooth chip evacuation and a consistent surface finish.

This end mill is used in CNC machining centers and manual milling machines for operations including 3D profiling, slotting, and finish passes on molds, dies, and precision components. The 3/8-inch shank diameter fits standard collet chucks and end mill holders commonly found in both vertical and horizontal machining setups. The 2.5-inch overall length keeps deflection low during close-tolerance work. It is typically installed by machinists and CNC operators in job shop, toolroom, and production environments.

Key Features

• Micrograin solid carbide construction for high rigidity and long edge life
• TiCN coating reduces friction and extends tool life in ferrous and non-ferrous materials
• 4-flute spiral design with right-hand cut and right-hand flute direction for efficient chip removal
• 40-degree helix angle promotes smooth cutting action and improved surface finish
• Ball end geometry supports 3D contouring, profiling, and radius floor finishing
• Single-end design with 0.3438-inch cutting diameter and 0.875-inch length of cut

Compatibility

Designed for use in standard 3/8-inch collet chucks and end mill holders on CNC machining centers and manual knee mills; verify spindle taper and holder bore before installation.

Installation Notes

Installation is performed by machinists or CNC operators. Power down and lock out the machine spindle before inserting or removing the tool from the holder. Seat the shank to the full recommended insertion depth in the collet or end mill holder and torque the retention hardware per the toolholder manufacturer specification. Inspect the cutting edges and coating for chips or wear before each use; a damaged edge should not be run at full feed rates.
