Accupro 12177109 Ball End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12177109 is a solid carbide ball end mill designed for precision milling in metalworking and machining applications. With a 1/8 inch mill diameter and 4-flute spiral geometry, this single-end tool delivers clean material removal and smooth finishing passes. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. An AlTiN coating provides heat resistance and extended tool life when cutting hardened steels, stainless, and other demanding alloys. The micrograin carbide substrate adds rigidity and wear resistance. This tool is sized for benchtop CNC mills, vertical machining centers, and high-speed die and mold work where tight tolerances are required.

This end mill is suited for profiling, slotting, and 3D contouring on ferrous and non-ferrous materials. The ball nose profile allows full-radius cuts on complex curved surfaces, making it a common choice for mold cavities, die work, and contoured part features. The 1/8 inch shank matches standard ER collets and precision tool holders on CNC machining centers. Right-hand cutting direction and right-hand flute spiral are standard for conventional CNC spindle operation.

Key Features

• 1/8 inch mill diameter with matching 1/8 inch shank for direct collet fitment
• 4-flute spiral geometry for improved surface finish and feed rate capability
• 40-degree helix angle for efficient chip evacuation and reduced cutting forces
• AlTiN coating for heat resistance and extended tool life on hard and abrasive materials
• Micrograin solid carbide substrate for rigidity and wear resistance
• Single-end, right-hand cut configuration standard for CNC vertical mills

Compatibility

Designed for use in standard 1/8 inch ER collet chucks and precision tool holders on CNC vertical machining centers and benchtop mills. Suitable for ferrous metals, hardened steels, stainless steel, and similar alloys where AlTiN coating performance is required.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet to the recommended grip length before torquing the collet nut. Verify spindle runout within tool holder tolerance before beginning a cut. Always power down and lock out the spindle before changing tooling.
