Accupro 41346321 Ball End Mill 5/32 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 41346321 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 5/32 inch (0.1563 inch decimal) mill diameter and a 4-flute geometry, this tool delivers smooth cutting action and efficient chip evacuation in ferrous and non-ferrous materials. The AlTiCrN coating provides high heat resistance and extended tool life under demanding cutting conditions. A variable index flute spacing reduces harmonic vibration during the cut, improving surface finish quality. This is a single-end tool with a 3/16 inch shank diameter, suited for use in CNC machining centers and manual mills.

This ball end mill is used in applications requiring contoured surfaces, 3D profiling, slotting, and finishing passes in ferrous alloys, stainless steels, and hardened materials. The AlTiCrN coating makes it particularly well suited for high-speed dry or near-dry machining environments. Machinists and CNC operators in job shops, tool rooms, and production facilities will find this tool appropriate for tight-tolerance finishing work where a small-diameter ball nose profile is required.

Key Features

• 5/32 inch (0.1563 inch) ball nose diameter for small-feature contouring
• 4-flute design promotes efficient chip removal and improved surface finish
• AlTiCrN coating for high-temperature resistance and extended tool life
• Variable index flute spacing reduces chatter and vibration during cutting
• Solid carbide construction provides rigidity and wear resistance
• Single-end configuration with 3/16 inch straight shank for secure tool holder retention

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide ball end mill compatible with standard CNC machining centers and manual mills accepting a 3/16 inch shank diameter tool holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing tooling. Seat the 3/16 inch shank fully and evenly in a precision collet or end mill holder and torque the retention mechanism according to the tool holder manufacturer specifications. Verify runout at the tool tip before beginning the cut to protect both the workpiece and the tool.
