Accupro 32252678 Ball End Mill 3/16 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 32252678 is a single-end ball end mill designed for precision milling operations in metal and hard-material applications. Built from solid carbide, it delivers the rigidity and wear resistance required for high-speed cutting in ferrous and non-ferrous materials. The tool measures 3/16 inches (0.1875 inches) in diameter with a 0.1740-inch length of cut and a 2-inch overall length. An AlTiCrN coating provides thermal resistance and extended tool life in demanding machining environments. With four flutes and a variable index design, this end mill is suited for machinists and toolroom professionals running CNC or manual milling equipment.

This end mill is appropriate for finish and semi-finish milling of contoured surfaces, slots, and 3D profiles where a ball-nose geometry is required. Its compact 3/16-inch diameter makes it well-suited for detail work, die and mold machining, and tight-tolerance features in steel, stainless, and hardened alloys. The 0.6250-inch neck length allows reach into deeper pockets without sacrificing rigidity. It is sold as a single-end tool, meaning the cutting geometry is on one end only.

Key Features

• Solid carbide construction for maximum rigidity and wear resistance
• AlTiCrN coating for high-temperature performance and extended tool life
• 4-flute design improves surface finish and material removal rate
• Variable index flute spacing reduces chatter and vibration during cutting
• 0.6250-inch neck length enables reach into deep pockets and cavities
• Single-end configuration with 3/16-inch shank for standard collet compatibility

Compatibility

Designed as a direct-fit replacement for standard 3/16-inch shank ball end mill applications in CNC machining centers and manual mills using ER or similar collet systems that accept a 0.1875-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a clean, properly sized collet or end mill holder to seat the shank securely and minimize runout. Follow the machine manufacturer and tooling manufacturer guidelines for recommended speeds and feeds based on workpiece material.
