Accupro 14881862 Ball End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14881862 is a solid carbide ball end mill designed for precision milling in tight geometries and complex contoured surfaces. Built on a miniature series platform, it features a 1/4 inch mill diameter, 3/8 inch length of cut, and a 4 inch overall length with a 1/4 inch shank diameter. The 30-degree helix angle and three-flute spiral configuration promote efficient chip evacuation and smooth cutting action. An AlTiN coating increases surface hardness and thermal resistance, extending tool life in abrasive and hard materials. The micrograin carbide substrate adds toughness and edge retention. This tool is installed by machinists and CNC tooling professionals in production and job shop environments.

This ball end mill is suited for finish milling, profiling, and 3D contouring operations on ferrous and non-ferrous materials including hardened steels, stainless, and cast iron. The extended reach neck geometry and 2 millimeter neck length allow access to recessed features and deep pockets where standard tools cannot reach. Single-end construction keeps setup simple and consistent. It is appropriate for vertical machining centers, CNC routers, and manual mills with appropriate collet or end mill holder tooling.

Key Features

• Solid micrograin carbide construction for edge retention in demanding cuts
• AlTiN coating provides thermal resistance and reduces tool wear in hard and abrasive materials
• Three-flute spiral design promotes chip flow and surface finish quality
• 30-degree helix angle balances cutting efficiency and lateral load
• Extended reach geometry with 2 millimeter neck length for deep or recessed features
• Chipbreaker geometry included to manage chip size in long-running cuts

Compatibility

Designed as an OEM-style miniature series ball end mill compatible with standard 1/4 inch collets and end mill holders used in CNC vertical machining centers and manual milling machines.

Installation Notes

Installation should be performed by qualified machinists or CNC tooling personnel. Confirm collet or holder bore matches the 1/4 inch shank diameter and that runout is within acceptable tolerance before running. Power down and lock out the spindle before loading or removing the tool. Do not exceed the tool manufacturer's recommended depth of cut or feed rate for the material being machined.
