Accupro 12184938 Ball End Mill 0.375 in 4 Flute Ticn Carbide

Product Description

The ACCUPRO 12184938 is a solid carbide ball end mill designed for high-performance milling of ferrous and non-ferrous materials. With a 0.375-inch mill diameter, 1-inch length of cut, and a 40-degree helix angle, this tool is built for aggressive material removal and excellent surface finishes. The TiCN coating increases surface hardness and reduces friction, extending tool life in demanding applications. Micrograin carbide construction provides the toughness and rigidity needed for long-reach and high-speed operations. This is a single-end, right-hand cutting tool installed by machinists and tooling technicians in CNC and manual milling operations.

This ball end mill is suited for profiling, contouring, slotting, and 3D surface milling in ferrous metals, alloy steels, and similar materials. The long overall length of 4 inches makes it appropriate for deep-cavity and extended-reach applications where standard-length tools cannot reach. The 4-flute spiral configuration improves chip evacuation and surface finish quality in both roughing and finishing passes. Typical installations include CNC machining centers and manual knee mills in production and job-shop environments.

Key Features

• 0.375-inch mill diameter with 1-inch length of cut for precise material engagement
• TiCN coating for improved hardness, wear resistance, and reduced built-up edge
• Micrograin solid carbide construction for rigidity and extended tool life
• 40-degree helix angle promotes smooth cutting action and efficient chip flow
• 4-flute spiral design supports higher feed rates and improved surface finish
• Long series at 4 inches OAL enables extended-reach milling in deep cavities

Compatibility

Designed as an OEM-style replacement or direct-fit tooling solution for standard 3/8-inch collet or end mill holder systems used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the milling machine spindle is fully powered down and at rest before changing tooling. Secure the shank in a properly sized collet or end mill holder and tighten to the tool holder manufacturer's specified procedure. Verify runout with a dial indicator before beginning a cut to confirm proper seating.
