Accupro 12184811 Ball End Mill 0.375 in 4 Flute Carbide

Product Description

The ACCUPRO 12184811 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. With a 0.375-inch mill diameter and a 0.625-inch length of cut, this tool handles contoured surfaces, radius milling, and 3D profile work in a single-end configuration. The 4-flute geometry and 40-degree helix angle promote efficient chip evacuation while maintaining surface finish quality. Constructed from micrograin solid carbide, the tool holds tight tolerances and resists wear under demanding cutting conditions. The uncoated finish makes it well suited for applications where coating compatibility with the workpiece material is a concern.

This end mill is intended for use in CNC machining centers and manual milling machines operating in job shop, tool-and-die, and production environments. The stub-length profile provides rigidity and reduces deflection during aggressive side milling or profiling passes. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling setups. Machinists working in aerospace, mold making, and general precision machining will find the micrograin carbide construction suitable for hardened and abrasive materials.

Key Features

• 0.375-inch mill diameter with a tight tolerance of +0.000 to -0.002 inches
• 0.625-inch length of cut and 2.0-inch overall length in a stub-length profile
• 4-flute spiral flute design with a 40-degree helix for improved chip flow
• Micrograin solid carbide construction for extended tool life and edge retention
• Uncoated finish suitable for a broad range of ferrous and non-ferrous workpiece materials
• Single-end, right-hand cut configuration with no chipbreaker for smooth finishing passes

Compatibility

Designed as a standard shank replacement ball end mill for CNC milling machines and manual mills accepting a 0.375-inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist familiar with end mill holder torque procedures and runout verification. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Confirm collet size matches the 0.375-inch shank diameter and verify shank engagement depth meets the tool holder manufacturer specifications. Check runout at setup to confirm the tool seats correctly before beginning a cut.
