Accupro 12465429 Ball End Mill 0.016 in 2 Flute Carbide

Product Description

The ACCUPRO 12465429 is a miniature solid carbide ball end mill designed for precision milling operations requiring a very small cutting diameter. With a 0.016-inch mill diameter and a 0.024-inch length of cut, this single-end tool is built for fine detail work in tight geometries. The micrograin carbide construction provides the rigidity and edge retention needed for accurate results in demanding applications. A 30-degree right-hand helix promotes efficient chip evacuation and stable cutting action. This tool is intended for use by machinists and tooling professionals working with CNC mills or manual machines requiring high-precision small-diameter end mills.

This end mill suits applications where fine-feature milling is required in materials that demand sharp, rigid tooling. The stub length classification and miniature series designation make it well suited for shallow-pocket work, engraving, and contour milling in confined areas. The bright uncoated finish is appropriate for a range of base materials where coating is not required. It is commonly used in mold and die work, medical component machining, and precision aerospace part manufacturing where tight tolerances and small feature sizes are critical.

Key Features

• 0.016-inch mill diameter with a mill diameter tolerance of +0.0000 to -0.0010 inches for tight dimensional control
• Micrograin solid carbide construction for superior edge retention and rigidity at miniature scales
• 30-degree right-hand spiral helix for effective chip evacuation during cutting
• 2-flute geometry optimized for small-diameter, fine-detail milling passes
• Stub length classification with 0.024-inch length of cut for stability in shallow-feature work
• Bright uncoated finish suitable for applications where coating is not required

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC and manual milling machines accepting a 1/8-inch shank diameter in applications requiring miniature series ball end mills.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Ensure the machine spindle is fully powered down and at rest before inserting or removing the end mill from the tool holder. Verify the 1/8-inch shank seats fully and is clamped securely to minimize runout, which is critical at this diameter. Do not exceed recommended speeds and feeds for 0.016-inch carbide tooling, as micro-diameter end mills are sensitive to deflection and breakage.
