Accupro 12184904 Ball End Mill 0.375 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12184904 is a solid carbide ball end mill designed for precision milling operations in metal cutting and machining applications. With a 0.375 inch diameter and a 1.75 inch length of cut, this tool handles profiling, contouring, and 3D surface milling where a radiused tip is required. The four-flute, right-hand spiral design at a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin solid carbide construction provides rigidity and wear resistance suited to demanding cutting conditions. The uncoated finish makes this tool straightforward to regrind when needed. Overall length is 4 inches, placing it in the extra-long category for extended reach applications.

This ball end mill is used in vertical machining centers and CNC milling operations where deep cavities, core and cavity work, or contoured surfaces require a long-reach tool. The extra-long 4 inch overall length with a 1.75 inch length of cut allows access to features that standard-length end mills cannot reach. The 3/8 inch shank diameter fits standard collets and end mill holders common in production and job shop environments. Machinists and CNC operators in aerospace, mold and die, and general metalworking will find this tool applicable to a wide range of profiling and finishing passes.

Key Features

• 0.375 inch ball end diameter for radiused profiling and 3D contouring
• Micrograin solid carbide construction for hardness and wear resistance
• 4-flute, right-hand spiral design at 40-degree helix for efficient chip removal
• 1.75 inch length of cut with 4 inch overall length for extended reach
• Single-end configuration with uncoated finish for easy reconditioning
• Mill diameter tolerance of +0.000 to -0.002 inches for consistent fitment

Compatibility

Designed as a direct-fit replacement or production ball end mill for standard 3/8 inch collets and end mill holders used in CNC vertical machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before installing or removing the tool. Seat the shank fully into the collet or tool holder to the recommended engagement depth and torque the retention hardware per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
