Accupro 14881827 Ball End Mill 0.025 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14881827 is a miniature single-end ball end mill designed for precision milling in tight geometries and fine-detail work. Built from micrograin solid carbide, it holds a 0.025-inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for consistent, repeatable results. The AlTiN coating improves heat resistance and tool life in ferrous and hardened materials. With a 3-flute spiral configuration and a 30-degree helix angle, this end mill balances chip evacuation with surface finish quality. Machinists and toolroom technicians running CNC mills or precision manual mills are the primary users of this tool.

This end mill is suited for contouring, slotting, and profiling operations where a small-diameter ball nose profile is required. The extended reach geometry, with a 0.25-inch neck length and 0.125-inch length of cut, allows access to features in pockets and cavities that standard-reach tools cannot reach. The 1/8-inch shank diameter fits standard collets and tool holders common on CNC machining centers and micro-milling setups. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle rotation.

Key Features

• 0.025-inch ball nose cutting diameter with tight tolerance: +0.0000 / -0.0010 inches
• Micrograin solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat resistance and extended tool life
• 3-flute spiral design with 30-degree helix angle for efficient chip removal and improved finish
• Extended reach with 0.25-inch neck length for deep-pocket and cavity access
• Single-end configuration, right-hand cut, right-hand flute direction

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC machining centers and micro-milling applications that accept a 1/8-inch shank diameter via standard collet or tool holder systems.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the 1/8-inch shank in a properly sized collet or end mill holder and verify runout before operation. Do not exceed the tool manufacturer's recommended speeds and feeds for the material being cut. Inspect the cutting edges and coating condition before each use, as micrograin carbide at this diameter is brittle and susceptible to chipping if mishandled or dropped.
