Accupro 14881877 Ball End Mill 1/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14881877 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles. Built in the Miniature Series, it features a 1/8 inch diameter cutting head with a 3/16 inch length of cut and a 2-1/2 inch overall length. The three-flute geometry paired with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action in tight-tolerance applications. An AlTiN coating provides thermal resistance and wear protection, extending tool life during high-speed operations. This end mill is used by machinists and tooling professionals across job shops, production facilities, and tool rooms.

This tool is suited for milling ferrous and hardened materials where heat resistance and edge retention are critical. The extended reach design, with a 5/8 inch neck length, allows access to deep pockets and recessed features without interference. The single-end configuration and right-hand cutting direction make it a standard fit for conventional CNC vertical machining centers and manual knee mills running right-hand spindle rotation. The micrograin carbide grade supports use in demanding cut conditions at elevated surface speeds.

Key Features

• 1/8 inch mill diameter with a 3/16 inch length of cut for precise miniature milling
• AlTiN coating for elevated heat resistance and extended tool life
• 3-flute spiral flute design with chipbreaker for efficient chip removal
• 30-degree helix angle for smooth cutting action and reduced vibration
• 5/8 inch neck length provides extended reach into deep pockets
• Micrograin solid carbide substrate for edge sharpness and wear resistance

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and milling machines accepting a 1/8 inch shank diameter end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify the collet or tool holder is rated for the 1/8 inch shank diameter and that runout is within acceptable tolerance before beginning a cut. Follow the machine tool manufacturer guidelines for speed and feed parameters appropriate to the workpiece material.
