Accupro 14788669 Ball End Mill 0.313 in 3 Flute Carbide

Product Description

The ACCUPRO 14788669 is a solid carbide ball end mill designed for precision milling operations in metal cutting and finishing applications. With a 0.313 inch mill diameter and a 1 inch length of cut, this 3-flute tool delivers smooth material removal and accurate contour work. The AlTiN+ coating provides thermal resistance and extended tool life when cutting hardened steels, stainless, and other demanding materials. The cylindrical shank is sized at 0.313 inches, matching the mill diameter for direct tool holder clamping. At 4 inches overall length, the tool balances reach and rigidity for most standard milling setups.

This ball end mill is suited for CNC machining centers and manual knee mills handling profiling, slotting, and 3D contouring work. The medium flute type and 3-flute geometry support chip evacuation in both roughing and finishing passes on ferrous and non-ferrous workpieces. It is commonly used in job shops, tool rooms, and production environments where consistent surface finish and dimensional accuracy are required.

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide ball end mill compatible with standard cylindrical tool holders accepting a 0.313 inch shank diameter.

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 an e-stop or powered-down state before changing tooling. Seat the shank fully into the tool holder and torque the set screw or collet nut per the tool holder manufacturer specification. Verify runout with a dial indicator before commencing a cut to protect both the tool and the workpiece.
