Accupro 14788668 Ball End Mill 0.25 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14788668 is a solid carbide ball end mill designed for precision milling in metalworking and machining applications. With a 0.25 inch cutting diameter and a 1 inch length of cut, this tool handles contouring, profiling, and finishing operations on hardened and abrasive materials. The AlTiN+ coating provides high-temperature resistance and reduces friction at the cutting edge, extending tool life in demanding cuts. Three medium flutes deliver a balance of chip clearance and cutting edge strength. A cylindrical shank measures 0.25 inches in diameter for secure tool-holder engagement. Licensed machinists and CNC operators are the primary users of this end mill.

This ball end mill is suited for use on CNC machining centers and manual mills handling ferrous and non-ferrous metals, hardened steels, and cast iron. It is a strong fit for die and mold work, contour milling, and complex 3D surface finishing where a consistent ball-nose radius is required. The 4 inch overall length provides adequate reach for most standard cavity and profiling work without excessive overhang. No extended reach version, so setups should plan for direct chuck or collet holding with minimal stick-out to reduce vibration.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed applications
• AlTiN+ coating enhances heat resistance and tool life on hardened and abrasive workpieces
• 3-flute medium flute geometry balances chip evacuation with edge strength
• 0.25 inch cutting diameter with 1 inch length of cut for precise profiling and contouring
• Cylindrical shank at 0.25 inches diameter for standard ER collet or end mill holder compatibility
• 4 inch overall length suits most standard machining center setups

Compatibility

Designed as an OEM-style solid carbide ball end mill suitable for CNC machining centers and manual mills accepting a 0.25 inch cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank fully into the collet or end mill holder and tighten to the tool-holder manufacturer's specified torque procedure. Minimize tool stick-out to reduce vibration and deflection, which is critical with small-diameter carbide end mills to prevent breakage.
