Accupro 12184351 Ball End Mill 0.25in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12184351 is a solid carbide ball end mill designed for precision milling operations in metal fabrication and machining environments. Built from micrograin solid carbide and coated with AlTiN, it delivers strong heat resistance and extended tool life at elevated cutting speeds. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With a 0.25-inch mill diameter and 3-flute geometry, this single-end tool is sized for detail work, contour milling, and profile passes in ferrous and non-ferrous materials. It is installed and operated by machinists and toolroom professionals working with CNC machining centers and manual mills.

This end mill suits applications in die and mold work, aerospace component machining, and general metalworking where tight tolerances and surface finish quality are priorities. The 0.75-inch length of cut supports moderate-depth passes, while the 2.5-inch overall length keeps overhang manageable for rigidity. The right-hand cutting and right-hand flute direction are standard for conventional CNC setups. The AlTiN coating makes this tool a practical choice for dry or near-dry cutting in hardened steels and high-temperature alloys.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention
• AlTiN coating provides heat resistance for high-speed and dry machining
• 3-flute spiral geometry balances chip clearance with surface finish quality
• 40-degree helix angle promotes smooth cutting and efficient chip evacuation
• Single-end ball profile for contour, profile, and 3D surface milling
• Right-hand cut and right-hand flute for standard CNC compatibility

Compatibility

Designed as a standard 0.25-inch shank ball end mill compatible with CNC machining centers and manual milling machines equipped with collets or end mill holders accepting a 0.25-inch shank diameter.

Installation Notes

This tool is installed and operated by qualified machinists. Secure the shank fully in a collet or end mill holder to the manufacturer-specified engagement depth before operation. Verify spindle runout is within acceptable limits before cutting to protect tool life and part accuracy. Follow applicable shop safety standards and machine manufacturer guidelines when setting speeds and feeds for the workpiece material.
