Accupro 72035199 Ball End Mill 5/16 Inch 6 Flute Carbide

Product Description

The ACCUPRO 72035199 is a solid carbide ball end mill designed for high-performance milling in demanding materials. Built with six flutes and a variable helix geometry of 36 and 40 degrees, it delivers reduced chatter and improved surface finish in tight-tolerance work. The AlTiN+ coating provides elevated heat resistance and wear protection, making it well suited for aggressive cuts at higher spindle speeds. At 0.3125 inches in diameter with a 0.7500-inch length of cut, this tool handles profiling, contouring, and finishing passes in ferrous and high-temperature alloy workpieces. Licensed machinists and CNC operators are the primary end users.

This end mill is optimized for machining high-temperature alloys, classified under workpiece material code S. The variable index and variable helix design work together to suppress harmonic vibration during long finishing passes. The single-end configuration and straight shank fit standard collet and end mill holders used on vertical machining centers and multi-axis CNC platforms. It is part of the ACCUPRO HS series, offered in fractional inch sizing.

Key Features

• AlTiN+ coating for high heat and wear resistance in hard materials
• Variable helix (36 and 40 degrees) and variable index for vibration damping
• Six-flute helical design for improved chip evacuation and surface finish
• Centercutting geometry allows plunge entry into the workpiece
• Solid carbide construction for rigidity and dimensional stability
• Right-hand cut and right-hand flute, single-end configuration

Compatibility

Designed for use in standard straight-shank collet chucks and end mill holders on CNC vertical machining centers and multi-axis mills. Primary workpiece material is high-temperature alloy (material code S). No specific machine model compatibility was provided by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the straight shank fully into the collet or holder to the recommended gauge-line depth before torquing the retention mechanism. Verify runout with a dial indicator after clamping, as excessive runout will accelerate edge wear on carbide tooling.
