Accupro 12463685 Ball End Mill 0.0550 in 2 Flute Carbide

Product Description

The ACCUPRO 12463685 is a miniature solid carbide ball end mill designed for high-precision milling in tight geometries and fine-detail work. The cutting diameter measures 0.0550 inches with a length of cut of 0.1650 inches, making it suited for small-radius contour milling, slotting, and 3D profiling passes. The 2-flute geometry and 30-degree right-hand spiral helix promote efficient chip evacuation at elevated spindle speeds. Micrograin carbide construction provides rigidity and edge retention in hardened and abrasive workpiece materials. This end mill ships in a bright, uncoated finish and is configured as a single-end tool.

This miniature ball end mill is used in CNC machining centers and manual mills where small-diameter, high-precision cutting is required. Typical applications include die and mold work, medical component machining, aerospace detail parts, and intricate fixturing. The 1/8-inch shank diameter fits standard collets and tool holders common to benchtop and full-size vertical machining centers. The 1.5-inch overall length keeps overhang minimal, supporting rigidity during fine finishing passes in shallow-to-moderate cavity depths.

Key Features

• 0.0550-inch ball nose cutting diameter for fine-detail and contour work
• Micrograin solid carbide construction for edge retention in hard and abrasive materials
• 2-flute, 30-degree right-hand helix for efficient chip flow at high RPM
• Bright/uncoated finish suitable for a wide range of workpiece materials
• Single-end configuration with 1/8-inch shank for compatibility with standard collets
• Tight diameter tolerance of +0.0000 / -0.0010 inches for repeatable fitment

Compatibility

Designed as an OEM-style miniature ball end mill for use in standard 1/8-inch collet or tool holder systems on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and de-energized before changing tooling. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut per the tool holder manufacturer specification. At 0.0550-inch diameter, this tool is susceptible to breakage from excessive feed rate, runout, or improper clamping — verify TIR before production runs.
