Accupro 14788622 Ball End Mill 0.25in 2 Flute Solid Carbide

Product Description

The ACCUPRO 14788622 is a 2-flute solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.25-inch milling diameter and a 1.5-inch length of cut, it handles profiling, contouring, and 3D surfacing in die and mold work, aerospace components, and general machining applications. The AlTiN+ coating provides elevated heat resistance and extended tool life at higher cutting speeds. A 0.25-inch cylindrical shank ensures secure chuck or collet retention, and the 4-inch overall length gives sufficient reach for most standard setups.

This end mill is suited for CNC machining centers and manual mills running at moderate-to-high spindle speeds on hardened steels, stainless alloys, titanium, and cast iron. The medium flute geometry balances chip evacuation with wall finish quality, making it a practical choice for finishing and semi-finishing passes. Machinists working in tool and die, mold making, and precision part fabrication will find the 0.25-inch diameter appropriate for tight-radius features and blended surface transitions.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN+ coating improves heat resistance and extends tool life at elevated cutting temperatures
• 2-flute ball nose geometry suited for 3D contouring, profiling, and finish passes
• Medium flute type balances chip flow and surface finish
• 0.25-inch cylindrical shank fits standard collets and end mill holders
• No chipbreaker design supports smooth finishing cuts

Compatibility

Designed as a direct-fit replacement-style ball end mill for CNC machining centers and manual mills accepting a 0.25-inch cylindrical shank with standard ER or end mill collet toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully in a clean, properly sized collet or end mill holder to the manufacturer-specified engagement depth before tightening. Inspect the tool for runout after installation using a dial indicator before beginning any cut cycle. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool.
