Accupro 39155486 Ball End Mill 3/16 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 39155486 is a single-end ball end mill designed for precision milling operations in metal cutting and machining applications. Built from solid carbide and finished with an AlTiCrN coating, it delivers hardness and heat resistance suited to high-speed cutting in ferrous and non-ferrous materials. The tool measures 3/16 inches in diameter with a 2-inch overall length and a 0.1600-inch length of cut. Four flutes with a variable index geometry reduce chatter and improve surface finish in finish-milling passes. Machinists and CNC operators working in job shops, tool rooms, and production environments install this end mill for contour milling, profiling, and slotting in tight-tolerance work.

This ball end mill is suited for use in CNC machining centers and manual mills where small-diameter, close-tolerance cuts are required. The 3/16-inch shank diameter allows direct chucking in standard collet systems. The AlTiCrN coating extends tool life when cutting hardened steels, stainless alloys, and similar difficult materials at elevated cutting speeds. The single-end configuration makes it a straightforward drop-in for worn or broken tooling in existing setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-material cutting
• AlTiCrN coating provides heat resistance and extends tool life at high cutting speeds
• Variable index flute geometry reduces vibration and improves surface finish
• 4-flute design for efficient chip evacuation and finish-quality passes
• 0.1250-inch neck length supports reach into shallow pockets and contours
• Single-end configuration for straightforward collet or chuck installation

Compatibility

Designed as a solid carbide ball end mill replacement compatible with standard 3/16-inch collet and end mill holder systems used in CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before changing tooling. Seat the shank fully and evenly in the collet or tool holder and torque the retention mechanism to the machine or holder manufacturer specification. Inspect the tool for runout after installation before beginning the cut.
