Accupro 14788641 Ball End Mill 0.25 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14788641 is a 3-flute solid carbide ball end mill designed for precision milling of contoured surfaces, pockets, and complex 3D profiles. With a 0.25 inch mill diameter and 0.75 inch length of cut, this tool delivers consistent performance in ferrous and non-ferrous materials. The AlTiN+ coating provides elevated heat resistance and extended tool life in high-speed and dry machining applications. The cylindrical shank measures 0.25 inches in diameter and the overall tool length is 2.5 inches, making it well-suited for standard toolholder setups on CNC machining centers and milling machines.

This end mill is intended for use in CNC milling operations where a ball nose profile is required for finish passes, 3D contouring, and radius form work. The medium flute geometry and solid carbide construction support both roughing and finishing in steel, stainless, aluminum, and hardened materials. It is commonly installed by machinists and toolroom operators in job shop, production, and maintenance environments.

Key Features

• 0.25 inch ball nose diameter for precise radius and contour milling
• 3-flute medium flute geometry balances chip evacuation and surface finish
• Solid carbide construction for rigidity and heat resistance
• AlTiN+ coating extends tool life in high-temperature and dry cutting conditions
• 0.25 inch cylindrical shank for compatibility with standard collets and toolholders
• No chipbreaker — suited for continuous-cut finishing and semifinishing passes

Compatibility

Designed for use with standard 0.25 inch ID collets, end mill holders, and shrink-fit toolholders on CNC vertical and horizontal machining centers requiring a ball nose end mill.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading tooling. The cylindrical shank should be seated to the minimum clamping depth specified by the toolholder manufacturer to prevent pullout. Verify runout with a dial indicator after seating to confirm proper fitment before initiating a cut.
