Accupro 12184972 Ball End Mill 0.375 in 4 Flute Carbide Altin

Product Description

The ACCUPRO 12184972 is a solid carbide ball end mill designed for high-performance milling in demanding machining environments. With a 0.375 inch cutting diameter and a 3 inch length of cut, this extra-long single-end mill is built for deep cavity work, profiling, and contouring operations where reach and rigidity both matter. The 4-flute, right-hand spiral configuration combined with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. The AlTiN coating adds hardness and thermal resistance, making this tool well-suited for dry or near-dry cutting in ferrous and hardened materials. Micrograin carbide construction provides consistent edge retention across extended production runs.

This end mill is a practical choice for mold and die work, aerospace components, and general precision machining where a full 3 inch depth of cut is required. The extra-long 6 inch overall length provides clearance for deep pockets and complex geometries on multi-axis CNC machining centers. Right-hand cutting direction is standard for conventional VMC and HMC spindle configurations. The 0.375 inch shank diameter fits standard ER and side-lock toolholders commonly used in production shops.

Key Features

• Solid micrograin carbide construction for superior edge retention and rigidity
• AlTiN coating provides thermal resistance and extended tool life in ferrous materials
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Extra-long 6 inch OAL with 3 inch LOC for deep cavity and pocket milling
• 4-flute right-hand spiral geometry for balance between chip clearance and finish quality
• Single-end design with 0.375 inch ball nose for profiling and 3D contouring

Compatibility

Designed for use in CNC machining centers with standard 0.375 inch ER collet chucks, shrink-fit holders, or side-lock toolholders. Suited for right-hand spindle rotation applications requiring an extra-long reach ball end mill.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the toolholder to the recommended gauge line to minimize runout and prevent pull-out under cutting loads. Verify tool runout with a dial indicator before beginning production cuts, particularly given the extra-long reach of this tool.
