Accupro 12184650 Ball End Mill 0.375 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12184650 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and hardened material applications. With a 0.375-inch diameter and a 4-flute spiral configuration, it delivers smooth cutting action and efficient chip evacuation. The TiCN coating increases surface hardness and wear resistance, extending tool life in demanding cuts. The 40-degree helix angle reduces cutting forces and improves surface finish quality. This tool is intended for use by machinists and CNC operators working in job shops, aerospace, tooling, and general manufacturing environments.

This end mill fits standard 3/8-inch tool holders and collet chucks. With a 0.875-inch length of cut and a 2.5-inch overall length, it suits short to medium reach milling passes. The single-end configuration and right-hand cutting direction are consistent with standard CNC vertical machining center setups. Micrograin carbide construction supports use in harder workpiece materials where high-speed steel tooling would wear prematurely. It is suited for slot milling, profile milling, and contour finishing passes where a ball-nose geometry is required.

Key Features

• 0.375-inch ball nose diameter for contour and 3D profile milling
• 4-flute spiral design for efficient chip evacuation and improved surface finish
• TiCN coating for increased wear resistance and extended tool life
• 40-degree helix angle reduces cutting forces on the workpiece
• Micrograin solid carbide construction supports use in hardened and abrasive materials
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit tool for standard 3/8-inch collet chucks and end mill holders used in CNC vertical machining centers and manual mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the control is in an idle or e-stop state before inserting or removing tooling. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Inspect the tool shank and collet bore for chips or debris before seating to avoid runout.
