Accupro 14788678 Ball End Mill 0.031 in 4 Flute Carbide

Product Description

The ACCUPRO 14788678 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles. With a 0.031-inch mill diameter and a 4-flute configuration, this tool delivers fine detail cutting in hardened steels, stainless, and high-temp alloys. The AlTiN+ coating provides elevated heat resistance and extended tool life under demanding cutting conditions. The medium flute type balances chip evacuation with surface finish quality. At 1.5 inches overall length with a 0.125-inch cylindrical shank, this end mill fits standard collet toolholding systems used in CNC machining centers and manual mills.

This end mill is suited for finishing passes on complex contours, die and mold work, and tight-tolerance profiling operations in job shop and production machining environments. The 0.094-inch length of cut makes it appropriate for shallow-to-moderate depth passes where rigidity and accuracy are critical. The solid carbide construction supports higher spindle speeds and feeds compared to HSS alternatives, making it a practical choice for machinists running ferrous and non-ferrous materials requiring a fine ball-nose profile.

Key Features

• 0.031-inch ball nose diameter for fine detail and contour milling
• 4-flute design supports improved surface finish and feed rate capability
• AlTiN+ coating resists heat and wear in hardened and abrasive materials
• Solid carbide construction for rigidity and dimensional stability
• Medium flute type balances chip flow and cutting edge strength
• Cylindrical shank fits standard collet and toolholder systems

Compatibility

Designed as a standard cylindrical-shank ball end mill compatible with CNC machining centers, knee mills, and other equipment accepting a 0.125-inch collet or toolholder.

Installation Notes

Installation is performed by qualified machinists using an appropriate collet or end mill holder torqued to the toolholder manufacturer's specification. Verify runout with a dial indicator before production use, as concentricity is critical at this diameter. Ensure the spindle and toolholder are clean and free of debris before seating the shank. Follow the cutting tool manufacturer's recommended speeds and feeds for the workpiece material.
