Accupro 12177183 Ball End Mill 0.75 in 4 Flute Carbide

Product Description

The ACCUPRO 12177183 is a solid carbide ball end mill designed for precision milling operations in metal, alloy, and composite materials. It features a 0.75 inch cutting diameter, 4 spiral flutes, and a 40-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The micrograin carbide construction delivers hardness and edge retention well beyond high-speed steel tooling. At 6 inches overall length with a 4.5 inch reach, this is a long-reach configuration suited for deep-cavity and contour milling work. It is installed and operated by machinists and tooling professionals in CNC machining centers and manual milling applications.

This ball end mill is used in applications requiring a full-radius cutting profile, including 3D contouring, die and mold work, and curved surface finishing. The long-reach geometry with a 1.5 inch length of cut and 4.5 inch reach length allows access to deep pockets and stepped features without tool interference. The right-hand cut and right-hand flute direction are standard for conventional CNC spindle rotation. This is a single-end tool with no chipbreaker and no variable helix or variable index features, making it straightforward to apply in standard toolpath programming.

Key Features

• 0.75 inch ball end cutting diameter for full-radius profiling and contour work
• 4 spiral flutes with 40-degree helix angle for efficient chip flow and reduced cutting forces
• Micrograin solid carbide construction for hardness and edge retention
• Long-reach configuration: 6 inches overall length, 4.5 inch reach length
• 1.5 inch length of cut suitable for moderate depth-of-cut passes in deep cavities
• Uncoated finish on micrograin carbide substrate — compatible with standard cutting fluids and coolant strategies

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 0.75 inch straight shank, with right-hand spindle rotation.

Installation Notes

Installation requires a collet chuck, end mill holder, or hydraulic toolholder sized for a 0.75 inch shank diameter. Ensure the spindle and toolholding system are fully de-energized and locked out before changing tooling. Verify runout with a dial indicator after seating the tool to confirm proper engagement and minimize premature edge wear. Follow the machine tool manufacturer and cutting tool manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
