Accupro 14881983 Ball End Mill 1/8 in 3 Flute Carbide

Product Description

The ACCUPRO 14881983 is a single-end ball end mill designed for precision milling in tight geometries and contoured surfaces. Built from micrograin solid carbide, it delivers the hardness and edge retention required for demanding cutting applications. The 1/8 inch diameter cutting face paired with a 3/16 inch length of cut makes this tool well suited for miniature-scale work where dimensional accuracy is critical. Three right-hand spiral flutes at a 30-degree helix angle promote efficient chip evacuation while maintaining smooth cutting action. The bright, uncoated finish makes it straightforward to inspect for wear. This tool is installed by machinists and CNC operators working with precision components.

This end mill belongs to the Miniature Series and is intended for small-diameter milling operations where tight tolerances and fine surface finishes are required. The extended reach design, combined with a 4 inch overall length and 2.25 mm neck length, allows access to recessed features and deep pockets without sacrificing rigidity. It is typically run in vertical machining centers, CNC milling machines, and high-speed spindle setups. Applications include die and mold work, prototype machining, medical component manufacturing, and aerospace part finishing where small-radius contours are common.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• 3-flute, right-hand spiral geometry at 30-degree helix for efficient chip removal
• Ball end profile for contouring, slotting, and 3D surface milling
• Extended reach design with 2.25 mm neck length for deep-pocket access
• Bright/uncoated finish suitable for a wide range of workpiece materials
• Mill diameter tolerance of +0.0000/-0.0010 inches for tight fitment in precision setups

Compatibility

Designed as an OEM-style miniature ball end mill compatible with standard 1/8 inch collets and toolholders used in CNC vertical machining centers and high-speed milling spindles.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and the tool changer is in a safe state before inserting or removing the end mill. Use a properly sized collet or shrink-fit holder matched to the 1/8 inch shank diameter to minimize runout. Verify shank engagement depth meets the toolholder manufacturer's minimum recommendation before beginning any cutting operation.
