Accupro 14883972 Ball End Mill 0.04 in 3 Flute Carbide

Product Description

The ACCUPRO 14883972 is a miniature solid carbide ball end mill designed for precision milling in tight geometries and small-feature applications. Built from micrograin carbide, it delivers the hardness and edge retention required for demanding cuts in ferrous and non-ferrous materials. The 0.04-inch diameter cutting edge is paired with a 3-flute spiral geometry and a 30-degree helix angle, providing efficient chip evacuation and smooth surface finishes. With an overall length of 2.5 inches and a 0.8-inch neck length, this tool provides extended reach into deep pockets and contoured profiles. It ships uncoated in a bright finish and is configured as a single-end tool with right-hand cut and right-hand flute direction.

This ball end mill is suited for die and mold work, prototype machining, and fine-detail contour milling where small-radius features are required. The miniature series designation places it in applications involving micro-machining on CNC vertical mills and machining centers. The 1/8-inch shank diameter fits standard miniature collet systems and tool holders used in high-speed spindle setups. It is typically installed and used by machinists and toolroom technicians working on precision components in aerospace, medical device, and mold-making environments.

Key Features

• 0.04-inch ball end diameter for fine-detail and small-radius milling
• Micrograin solid carbide construction for edge hardness and wear resistance
• 3-flute spiral geometry with 30-degree helix for efficient chip evacuation
• 0.8-inch neck length provides extended reach into deep features and pockets
• Right-hand cut and right-hand flute direction for standard CNC spindle use
• Bright uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as an OEM-style miniature ball end mill for use in standard 1/8-inch collet tool holders and high-speed CNC machining center spindles.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and the tool holder is clean and free of debris before seating the shank. Use a properly sized collet or tool holder rated for the 1/8-inch shank diameter and verify runout with a dial indicator before initiating cuts. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material.
