Accupro 12184508 Ball End Mill 0.4375 in 3 Flute Carbide

Product Description

The ACCUPRO 12184508 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.4375-inch (7/16-inch) mill diameter and a 1-inch length of cut, this single-end tool generates accurate contoured surfaces, pockets, and 3D profiles. The 3-flute geometry with a 40-degree right-hand spiral helix balances chip evacuation with surface finish quality. Micrograin carbide construction provides hardness and wear resistance suited to demanding CNC machining environments. This tool ships uncoated and is ready for use or post-purchase coating application based on shop requirements.

This ball end mill is suited for CNC machining centers and manual mills where contour milling, die-and-mold work, or finish profiling is required. The 0.4375-inch shank diameter matches the mill diameter for direct collet chuck mounting. The 4-inch overall length provides adequate reach for standard workholding setups without excessive overhang. Machinists working in job shops, tool rooms, and production environments will find this geometry appropriate for medium-depth cavity work and finishing passes on curved surfaces.

Key Features

• 0.4375-inch (7/16-inch) ball nose diameter for accurate radius profiling
• 3-flute design balances chip clearance and rigidity for finish milling
• 40-degree right-hand helix promotes smooth cutting action and chip flow
• Micrograin solid carbide construction for extended tool life in hard materials
• Single-end, uncoated — compatible with post-coat processing or use as-is
• 4-inch overall length with matched 7/16-inch shank for direct collet mounting

Compatibility

Designed as a direct-mount replacement or new tooling option for CNC machining centers and manual mills accepting a 7/16-inch collet or end mill holder. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and locked out before tool changes. Seat the shank fully into a properly sized collet or end mill holder and torque the retention nut to the toolholder manufacturer's specification. Confirm runout with a dial indicator before beginning the first cut to protect both the tool and the workpiece.
