Accupro 12184577 Ball End Mill 0.1378 in 4 Flute Carbide

Product Description

The ACCUPRO 12184577 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.1378-inch (3.50 mm) mill diameter and a 0.4724-inch (12.00 mm) length of cut, this tool handles contour milling, slotting, and 3D profiling in tight geometries. The 4-flute, single-end configuration with a 40-degree right-hand helix delivers efficient chip evacuation and smooth surface finishes. The micrograin carbide substrate provides the hardness and wear resistance needed for consistent performance in ferrous and non-ferrous materials. This tool ships uncoated and is ready for direct use or can accept aftermarket coatings based on application requirements.

This ball end mill is suited for CNC machining centers and manual mills where small-diameter finishing and semi-finishing passes are required. The 4.00 mm shank diameter fits standard collets and tool holders commonly found in production and job shop environments. With a 50.00 mm overall length and a regular length designation, it fits applications where reach requirements do not exceed standard tooling envelopes. Machinists and tool-and-die professionals working on mold cavities, die components, and precision part profiles will find this tool well-matched to their requirements.

Key Features

• 0.1378-inch (3.50 mm) ball nose diameter for precise contouring and profiling
• 4-flute spiral geometry with 40-degree right-hand helix for efficient chip removal
• Solid micrograin carbide construction for hardness and edge retention
• Single-end design with 0.4724-inch (12.00 mm) length of cut
• 4.00 mm shank diameter compatible with standard collet systems
• Uncoated finish suitable for direct use or post-coating treatment

Compatibility

Designed for use in CNC machining centers and milling machines equipped with collet or end mill holders accepting a 4.00 mm shank diameter. Suitable for right-hand spindle rotation applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and at a complete stop before inserting or removing the tool from the holder. Verify collet size matches the 4.00 mm shank diameter and that the tool is seated to proper engagement depth per the toolholder manufacturer guidelines. Inspect the cutting edges for chips or damage before each use.
