Accupro 12182218 Square End Mill 3/8 Inch 3 Flute Carbide

Product Description

The ACCUPRO 12182218 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 3/8-inch cutting diameter, a 1-1/8-inch length of cut, and a 3-inch overall length, making it well-suited for long-reach slotting, profiling, and peripheral milling operations. The TiCN coating provides increased surface hardness and lubricity compared to uncoated carbide, extending tool life in abrasive materials. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Micrograin carbide construction supports tight tolerances and consistent edge integrity across the tool life.

This end mill is used in CNC machining centers and manual milling machines for applications including slot milling, side milling, and contour profiling. The long series configuration provides additional reach for deeper pockets and stepped features. The centercutting geometry allows plunge entry, giving operators flexibility in toolpath strategy without requiring a separate drill operation. It is appropriate for job shops, production machining, and toolroom work where a reliable general-purpose end mill with extended reach is needed.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN finish for improved wear resistance on abrasive and hard materials
• 40-degree spiral helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut and right-hand flute configuration
• Long series length type with 1-1/8 inches of usable cut length

Compatibility

Designed as a general-purpose OEM-style square end mill compatible with standard 3/8-inch collet chucks, end mill holders, and shrink-fit tooling systems used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the shank to the full recommended grip depth in the tool holder and verify runout with a dial indicator before beginning a cut. Follow the machine tool manufacturer guidelines and applicable shop safety protocols when setting feeds, speeds, and depth of cut.
