Accupro 14797478 Ball End Mill 1/16 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14797478 is a miniature solid carbide ball end mill designed for precision milling in tight geometries and small-feature work. With a 1/16 inch (0.0625 inch) cutting diameter and a 3-flute spiral configuration, it delivers smooth chip evacuation and a quality surface finish in hardened and abrasive materials. The micrograin carbide substrate provides rigidity and edge retention that high-speed steel cannot match at this scale. A 30-degree right-hand helix angle balances cutting efficiency with tool stability. This end mill is used by machining professionals operating CNC mills and manual mills where small-diameter, fine-detail cutting is required.

This miniature ball end mill is suited for die and mold work, engraving, contouring, and 3D profiling operations in materials where small radii and tight tolerances are critical. Its long-length classification and 0.3120 inch length of cut make it appropriate for reaching into slots, pockets, and contoured surfaces where a standard-length tool cannot reach. It is a single-end tool sold individually, intended for professional machining environments requiring consistent dimensional accuracy on small features.

Key Features

• 0.0625 inch (1/16 inch) ball nose diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control
• 3-flute spiral flute geometry promotes efficient chip removal and improved finish quality
• Micrograin solid carbide construction for superior hardness and wear resistance compared to HSS
• 30-degree right-hand helix angle for balanced cutting forces in small-diameter applications
• Long-length series with 0.3120 inch LOC allows access to deeper features and contoured pockets
• Bright/uncoated finish suitable for non-ferrous metals, plastics, and general-purpose machining

Compatibility

Designed as an OEM-style miniature ball end mill for use in standard 1/8 inch collets or end mill holders on CNC machining centers and manual mills requiring small-diameter tooling.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Secure the 1/8 inch shank in a properly sized collet or end mill holder and torque to the machine manufacturer's specification. Inspect the cutting edges under magnification before use, as small-diameter carbide tools are brittle and susceptible to edge chipping if mishandled. Do not exceed recommended speeds and feeds for the workpiece material and tool diameter.
