Accupro 12184223 Ball End Mill 0.375in 2 Flute Carbide

Product Description

The ACCUPRO 12184223 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hard-material machining environments. With a 0.375-inch mill diameter and a 1.125-inch length of cut, this single-end tool generates smooth, contoured surfaces in both roughing and finishing passes. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Micrograin carbide construction provides the rigidity and edge retention needed for demanding CNC and manual milling applications. The uncoated finish suits shops that apply their own coatings or work in materials where uncoated tooling is preferred.

This end mill fits standard 3/8-inch toolholders and is classified as a long-length tool with a 3-inch overall length. It is appropriate for vertical machining centers, knee mills, and CNC routers performing profile milling, slotting, and 3D contouring work. Right-hand cut and right-hand flute direction are standard for conventional milling setups. The long-length designation provides extended reach for deeper cavities or workpiece features that shorter-reach tooling cannot access.

Key Features

• Solid micrograin carbide construction for high rigidity and extended edge life
• 0.375-inch mill diameter with a tolerance of +0.000 to -0.002 inches
• 1.125-inch length of cut for deep profiling and contouring passes
• 40-degree helix angle promotes chip flow and reduces heat buildup
• Spiral flute, right-hand cut and flute direction for standard milling setups
• Long-length overall at 3 inches with 3/8-inch shank for extended reach applications
• Uncoated finish — compatible with a wide range of workpiece materials

Compatibility

Designed as an OEM-style replacement and standard-fit ball end mill for 3/8-inch ID collets, end mill holders, and shrink-fit toolholders used on CNC machining centers and conventional knee mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle and machine are powered off and locked out before changing tooling. Seat the shank fully into the toolholder to the recommended engagement depth and verify runout with a dial indicator before running production cuts. Follow machine manufacturer torque specifications for collet nuts and retention knobs.
