Accupro 12184226 Ball End Mill 0.4375 in 2 Flute Carbide

Product Description

The ACCUPRO 12184226 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. With a 0.4375-inch (7/16-inch) cutting diameter and a 2-inch length of cut, this single-end tool delivers consistent performance on contoured surfaces, slots, and 3D profiling work. The micrograin carbide construction provides hardness and wear resistance suited to demanding cutting conditions. At 40 degrees helix and a right-hand flute direction, chip evacuation is efficient during high-speed passes. This tool is installed and operated by machinists and CNC programmers working on milling machines and machining centers.

This end mill is well suited to long-reach applications where a standard-length tool cannot access deep cavities or pockets. The 2-inch length of cut combined with a 4-inch overall length makes it a long-length tool appropriate for die and mold work, aerospace component machining, and precision part manufacturing. The uncoated finish makes it compatible with a broad range of workpiece materials where coated tooling is not required or preferred.

Key Features

• 0.4375-inch (7/16-inch) ball nose diameter for accurate radius profiling
• Solid micrograin carbide construction for hardness and extended tool life
• 2-inch length of cut for deep pocket and cavity access
• 40-degree helix angle promotes efficient chip evacuation
• Right-hand cutting direction, single-end configuration
• Uncoated finish suitable for a wide range of milling applications

Compatibility

Designed as an OEM-style replacement or direct-use ball end mill for standard milling machine and CNC machining center spindles accepting a 7/16-inch shank diameter.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the spindle and tool holder are fully de-energized and at rest before inserting or removing the end mill. Seat the 7/16-inch shank fully into the collet or end mill holder and torque the retaining nut to the tool holder specification. Verify runout with a dial indicator before beginning a cut to confirm proper seating and avoid premature tool wear.
