Accupro 12184386 Ball End Mill 7/16 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12184386 is a single-end ball end mill designed for precision milling operations in metal and hard-material applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for demanding profiling, contouring, and finishing cuts. The tool measures 0.4375 inches in diameter with a 1-inch length of cut and a 2.75-inch overall length. A TiCN coating reduces friction and heat buildup at the cutting edge, extending tool life in ferrous and non-ferrous materials. The 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. Machinists, tool-and-die professionals, and CNC operators typically select this end mill for high-accuracy work.

This end mill is suited for CNC machining centers and manual mills where ball-nose geometry is required for 3D contouring, radius profiling, and cavity work. The right-hand cutting direction and right-hand spiral flute configuration make it compatible with standard spindle setups. The 7/16-inch shank diameter fits common collet and end mill holder systems used in both production shops and toolroom environments. It is a single-end tool intended for direct chuck or collet mounting without adapters in most setups.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• TiCN coating reduces cutting friction and extends tool life in ferrous and non-ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes
• 3-flute geometry balances chip clearance with cutting edge strength
• Ball-nose profile enables 3D contouring, radius milling, and cavity profiling
• Right-hand cut and right-hand spiral for standard spindle compatibility

Compatibility

Designed as an OEM-style solid carbide ball end mill compatible with standard 7/16-inch collets and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the spindle fully powered down and locked before tool changes. Seat the 7/16-inch shank fully into the collet or end mill holder and torque the retention system according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or coating damage before each use. Follow applicable shop safety protocols and machine tool operating procedures during setup.
