Accupro 32308538 Ball End Mill 3/16 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 32308538 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 3/16 inch (0.1875 inch) mill diameter and a 4-flute configuration, this single-end tool delivers efficient chip evacuation and smooth finish cuts in ferrous and non-ferrous materials. The AlTiCrN coating provides high heat resistance and extended tool life in demanding cutting environments. The 0.1600 inch length of cut and 1.75 inch neck length make this tool well suited for reaching into tight pockets and contoured profiles. Licensed machinists and CNC operators are the primary users.

This ball end mill is intended for use in CNC machining centers and manual milling machines where a small-diameter, fine-finish tool is required. The 3-inch overall length and 3/16 inch shank diameter make it compatible with standard collet chucks and end mill holders commonly found in production and job-shop environments. It is suited for milling complex contours, cavity work, and finishing passes in hardened or abrasive materials where the AlTiCrN coating provides an advantage over standard TiN or TiAlN finishes. This is a single-end tool and is not reversible.

Key Features

• 0.1875 inch (3/16 inch) ball nose diameter for fine contour and cavity milling
• 4-flute geometry with variable index for reduced chatter and improved surface finish
• AlTiCrN coating for high-temperature wear resistance in hard and abrasive materials
• Solid carbide construction provides rigidity and dimensional stability over high-speed tool paths
• 1.75 inch neck length allows access to deep pockets without interference
• Single-end design with 3-inch overall length fits standard collet and end mill holder setups

Compatibility

Designed as a direct-fit replacement or standard addition for CNC machining centers and manual mills using 3/16 inch collet chucks or end mill holders. No specific OEM model compatibility is stated by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder and torque the retention mechanism per the machine tool manufacturer specifications. Confirm runout with a dial indicator before beginning a production run to avoid premature tool wear or part rejection.
