Accupro 33728841 Ball End Mill 5/32 in 4 Flute Carbide

Product Description

The ACCUPRO 33728841 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. It features a 5/32 inch (0.1563 inch decimal) mill diameter with a 0.1330 inch length of cut and a 3/16 inch (0.1875 inch decimal) shank diameter. The four-flute geometry supports efficient chip evacuation and surface finish quality. An AlTiCrN coating improves heat and wear resistance, extending tool life in demanding cutting conditions. With a 2 inch overall length and a 0.3750 inch neck length, this single-end mill suits CNC machining centers and manual mills where small-diameter cutting tools are required.

This end mill is suited for shops machining hardened steels, stainless steels, and other tough alloys where coating performance is critical. The variable index flute spacing reduces chatter and vibration during cuts, making it appropriate for finishing passes and contour work. It is typically installed and operated by machinists and CNC programmers in job shops, tool rooms, and production machining environments. Its single-end configuration means the tool is replaced when worn rather than indexed.

Key Features

• 5/32 inch ball nose diameter for small-radius contouring and detail work
• AlTiCrN coating for elevated heat resistance and extended tool life in hard materials
• 4-flute design balances material removal rate with chip clearance
• Variable index flute spacing reduces harmonic vibration during cutting
• Solid carbide construction provides rigidity and dimensional stability
• Single-end, 2 inch overall length fits standard small-diameter toolholders

Compatibility

Designed as a direct-fit replacement or new-install solid carbide ball end mill for CNC machining centers and manual milling machines accepting a 3/16 inch shank diameter collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool. Seat the shank fully and evenly in a clean, properly sized collet or end mill holder and torque the retention nut per the toolholder manufacturer specification. Inspect the cutting edges and coating for chips or damage before each use.
