Accupro 14881868 Ball End Mill 3/16 in 3 Flute Altin Carbide

Product Description

The ACCUPRO 14881868 is a solid carbide ball end mill designed for precision milling in demanding metalworking applications. It features a 3/16-inch diameter with a 9/32-inch length of cut and a 3-flute spiral geometry for improved chip evacuation and surface finish. The tool is coated with AlTiN (aluminum titanium nitride) for extended tool life in high-heat cutting environments such as hardened steels, stainless steel, and titanium alloys. With a micrograin carbide substrate and 30-degree helix angle, this end mill delivers stable cutting performance in tight-tolerance work. It is part of the ACCUPRO Miniature series and is installed by machinists and tool-and-die professionals.

This end mill is suited for CNC milling centers and manual mills requiring small-diameter, high-precision cutting. The extended reach design with a 1-1/2-inch neck length allows access to deeper pockets and complex contours without tool interference. The single-end configuration and right-hand cut with right-hand flute direction make it a standard fit for conventional CNC spindle setups. It is commonly used in mold and die work, aerospace component machining, and medical device manufacturing where fine detail and tight tolerances are required.

Key Features

• 3/16-inch ball end diameter with 9/32-inch length of cut for precise contouring
• AlTiN coating provides heat and wear resistance in hard material milling
• 3-flute spiral design with chipbreaker for efficient chip removal and improved finish
• Micrograin solid carbide substrate for rigidity and edge retention
• 30-degree helix angle balances cutting forces and surface quality
• Extended reach with 1-1/2-inch neck length for deep-pocket and complex-geometry access

Compatibility

Designed as an OEM-style replacement and standard-fit cutting tool for CNC machining centers and manual milling machines accepting a 3/16-inch shank diameter collet or tool holder.

Installation Notes

Installation is performed by machinists using an appropriate collet or end mill holder sized for a 3/16-inch shank. Ensure the spindle is fully powered down and locked before changing tooling. Verify runout with a dial indicator after seating the tool to confirm proper alignment before cutting. Follow your machine tool manufacturer guidelines for feed rate and spindle speed based on workpiece material.
