Accupro 14788655 Ball End Mill 0.25 in 3 Flute Carbide

Product Description

The ACCUPRO 14788655 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.25 inch cutting diameter and a 1.125 inch length of cut, it handles contoured surfaces, slotting, and profiling passes where a spherical tip geometry is required. The three-flute configuration provides a balance between chip evacuation and surface finish quality. An AlTiN+ coating improves heat resistance and tool life when cutting ferrous alloys and hardened steels. This tool is intended for use by machinists and tooling professionals on CNC mills and machining centers.

This ball end mill suits general-purpose and finishing operations in job shops, production machining environments, and tool rooms. The 0.25 inch shank diameter fits standard ER and end mill holders commonly found on vertical and horizontal machining centers. The medium flute type and cylindrical shank make it appropriate for a wide range of workpiece materials including alloy steels, stainless steels, and cast irons where AlTiN+ coating performance is most effective. It is sold individually as a single-piece unit.

Key Features

• 0.25 inch ball end cutting diameter for contour and profile milling
• 1.125 inch length of cut supports moderate-depth passes on complex geometries
• Three flutes balance material removal rate with chip clearance
• AlTiN+ coating extends tool life in high-heat cutting conditions
• Solid carbide construction provides rigidity and wear resistance
• Cylindrical shank with 0.25 inch diameter fits standard toolholders
• 3.0 inch overall length allows reach into moderate-depth features

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 0.25 inch cylindrical shank end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, particularly for finishing operations where surface quality is critical.
