Accupro 36421899 Ball End Mill 3/16 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 36421899 is a solid carbide ball end mill designed for high-performance milling in demanding shop environments. Built with four flutes and a variable index geometry, it delivers improved chip evacuation and reduced chatter during cutting operations. The AlTiCrN coating provides high-heat and wear resistance, making it well suited for hardened steels, stainless alloys, and other difficult-to-machine materials. At 3/16 inches in diameter with a 0.174-inch length of cut, this is a small-diameter tool built for detail work and tight-tolerance finishing passes. Machinists and tool-and-die professionals rely on this style of end mill for contour milling, profiling, and 3D surface work on CNC machining centers.

This end mill is appropriate for use in both production and prototype machining environments. Its single-end configuration and 3/16-inch shank diameter make it compatible with standard collet chucks and end mill holders sized for that shank. The 0.25-inch neck length provides clearance for shallow pocket and contour work without excessive tool deflection. The 2-inch overall length keeps the tool rigid at this diameter, which is critical when maintaining surface finish and dimensional accuracy on finish passes.

Key Features

• AlTiCrN coating for elevated heat and wear resistance in hard and abrasive materials
• 4-flute design promotes smooth finish and efficient material removal
• Variable index flute spacing reduces harmonic vibration and chatter
• Solid carbide construction for rigidity and dimensional stability
• Single-end configuration for use in standard end mill holders and collet chucks
• 0.25-inch neck length provides clearance for contour and profiling operations

Compatibility

Designed for use in CNC machining centers and manual mills equipped with collet chucks or end mill holders accepting a 3/16-inch shank diameter.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in a safe, locked-out state. Seat the shank fully and evenly in the collet or holder and torque the retention nut per the toolholder manufacturer specification. Inspect the cutting edges and coating for damage before each use. Small-diameter carbide end mills are brittle and should not be used to take interrupted cuts or side loads beyond the tool's rated depth of cut.
