Accupro 14788715 Ball End Mill 0.25 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788715 is a 4-flute solid carbide ball end mill designed for high-performance milling in ferrous and non-ferrous materials. It carries an AlTiN+ coating that increases surface hardness and heat resistance, extending tool life in demanding cutting conditions. The mill diameter is 0.25 inches with a matching 0.25-inch cylindrical shank, a 1.5-inch length of cut, and a 6-inch overall length. Solid carbide construction provides rigidity and wear resistance well beyond that of high-speed steel tooling. This end mill is installed and run by machinists and CNC operators in job shop and production environments.

This ball end mill is suited for profiling, contouring, and finishing operations where a full-radius cutting edge is required. The medium flute geometry balances chip evacuation with cutting edge strength. At 0.25 inches in diameter and 1.5 inches of usable cut length, it handles both shallow and deeper reach finishing passes in molds, dies, and general machining applications. The AlTiN+ coating makes it particularly effective at elevated spindle speeds and in harder workpiece materials where uncoated carbide would wear prematurely.

Key Features

• AlTiN+ coating for enhanced heat resistance and extended tool life in hard and abrasive materials
• Solid carbide construction delivers rigidity and edge stability at high feed rates
• 4-flute, medium flute type balances chip clearance and surface finish capability
• Ball end geometry enables full-radius profiling and 3D contouring operations
• Cylindrical shank provides consistent grip in standard end mill holders and collet chucks
• No chipbreaker design suits finishing and semi-finishing passes

Compatibility

Designed as a standard 0.25-inch shank ball end mill compatible with collet chucks, shrink-fit holders, and set-screw end mill holders sized for a 0.25-inch cylindrical shank.

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and lock out the spindle before changing tooling. Seat the shank fully and evenly in the holder to the minimum insertion depth recommended by the holder manufacturer before tightening. Inspect the cutting edges and coating for chips or damage before each use, and verify runout with a dial indicator after setup when tight tolerances are required.
