Accupro 12184753 Ball End Mill 0.1719 in 4 Flute Carbide

Product Description

The ACCUPRO 12184753 is a single-end ball end mill designed for precise contour milling, profiling, and 3D surface work in machining applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for hardened materials and high-speed cuts. The 0.1719-inch diameter cutting edge is paired with an AlTiN coating that improves heat resistance and extends tool life in ferrous and abrasive materials. With a 40-degree helix angle and four spiral flutes, this end mill provides efficient chip evacuation and a smooth surface finish. Machinists and CNC operators in tool shops, job shops, and production environments are the primary users.

This stub-length ball end mill is suited for close-tolerance finish passes, die and mold work, and pocket profiling where a small-diameter tool is required. The 3/8-inch length of cut and 3/16-inch shank diameter make it a fit for tight-clearance operations. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling centers. Its compact stub-length geometry reduces deflection during light finishing passes on ferrous alloys, stainless, and similar materials where AlTiN coating performance is most effective.

Key Features

• Micrograin solid carbide construction for hardness and wear resistance
• AlTiN coating improves thermal resistance and extends tool life in ferrous materials
• 40-degree helix angle promotes smooth cutting action and efficient chip flow
• Four spiral flutes for improved finish quality on contoured surfaces
• Stub-length geometry reduces deflection in precision finishing operations
• Single-end design with right-hand cut and right-hand flute direction

Compatibility

Designed for use in standard CNC milling machines and machining centers that accept a 3/16-inch shank diameter. Suitable for right-hand spindle rotation applications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine fully powered down and in a locked-out state per applicable safety procedures. Ensure the collet or tool holder is clean and rated for the 3/16-inch shank diameter before securing. Do not exceed the manufacturer-recommended speeds and feeds for the workpiece material and coating type. Verify runout after installation to protect edge integrity on this small-diameter tool.
