Accupro 14883983 Ball End Mill 0.085 in 3 Flute Carbide

Product Description

The ACCUPRO 14883983 is a miniature solid carbide ball end mill designed for precision milling operations requiring tight tolerances and fine detail work. With a 0.0850-inch mill diameter and a 0.1270-inch length of cut, this tool is engineered for small-feature contouring, slotting, and profiling in hardened and difficult-to-machine materials. The micrograin carbide construction provides the rigidity and wear resistance needed for consistent performance in demanding CNC milling applications. It is installed and used by machinists and tooling professionals working in job shops, aerospace, medical device, and mold-and-die environments.

This end mill fits standard 1/8-inch collet or chuck setups and is suited for CNC machining centers performing finish and semi-finish passes on small components. The extended reach neck design, with a 0.7000-inch neck length and 2-1/2-inch overall length, allows access to recessed features and deep cavities where standard-reach tooling cannot reach. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces in fine-feature work. Its bright/uncoated finish makes it a practical choice for non-ferrous metals, plastics, and graphite electrodes.

Key Features

• 0.0850-inch ball diameter with +0.0000/-0.0010 inch mill diameter tolerance for precise dimensional control
• Micrograin solid carbide construction for superior hardness and edge retention
• 3-flute geometry with 30-degree right-hand spiral for efficient chip removal
• Extended reach design with 0.7000-inch neck length for deep-cavity access
• Single-end, right-hand cutting configuration compatible with standard CNC setups
• Bright/uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed for use in 1/8-inch collet chucks and compatible toolholders on CNC milling machines. Part of the ACCUPRO Miniature series of solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully powered down and at a complete stop before changing tooling. Secure the shank to the specified collet or chuck torque per the machine tool manufacturer guidelines, observing the shank diameter tolerance of -0.0001/-0.0003 inch for proper fit. Do not exceed the recommended depth of cut or feed rate for the workpiece material, as carbide tooling is brittle and susceptible to breakage under excessive lateral load.
