Accupro 12184520 Ball End Mill 0.75in 3 Flute Carbide

Product Description

The ACCUPRO 12184520 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hardened material applications. With a 0.75-inch diameter and a 2-inch length of cut, this tool generates contoured, three-dimensional profiles and curved surfaces with consistent accuracy. The three-flute, right-hand spiral configuration at a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. The micrograin carbide construction delivers the hardness and thermal resistance required for demanding cutting conditions. This is a single-end, long-length tool with a 6-inch overall length and an uncoated finish, suited for machinists and toolroom professionals working on CNC machining centers and manual mills.

This ball end mill is intended for use in machine shops, tool and die operations, and production environments where contour milling, slot milling, and 3D profiling are required. The long-length configuration allows access to deeper cavities and workpiece features that standard-length end mills cannot reach. The 0.75-inch shank diameter matches the cutter diameter for direct chuck or collet mounting with minimal runout. Micrograin carbide grade makes this tool suitable for ferrous and non-ferrous materials in both roughing and finishing passes where tool life and dimensional accuracy are priorities.

Key Features

• 0.75-inch ball nose diameter for contoured and 3D surface milling
• 2-inch length of cut with 6-inch overall length for deep-reach applications
• 3-flute right-hand spiral design at 40-degree helix for efficient chip evacuation
• Micrograin solid carbide construction for hardness, wear resistance, and edge retention
• Uncoated finish suitable for a range of base materials without coating-related heat concerns
• Single-end configuration with matched 0.75-inch shank diameter for direct collet mounting

Compatibility

Designed as a direct-mount replacement or new-installation ball end mill for CNC machining centers and manual milling machines equipped with standard ER, CAT, BT, or straight-bore collet systems accepting a 0.75-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully powered down and locked out before tool changes. The shank should be inserted to the full recommended grip depth in the collet or chuck to minimize runout and tool pullout risk. Verify runout with a dial indicator before beginning the cut. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the specific workpiece material to avoid premature tool wear or breakage.
