Accupro 12184467 Ball End Mill 0.25in 3 Flute Carbide Ticn

Product Description

The ACCUPRO 12184467 is a single-end ball end mill designed for contouring, profiling, and 3D milling operations in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for demanding cutting conditions. The tool carries a TiCN (Titanium Carbonitride) coating that reduces friction and extends tool life at elevated cutting temperatures. With a 40-degree helix angle and three right-hand spiral flutes, it promotes efficient chip evacuation and smooth surface finishes. The extra-long length of cut makes it well suited for deep-pocket and deep-wall milling applications. Licensed machinists and CNC operators are the primary users of this tooling.

This end mill is intended for use in CNC machining centers and manual vertical mills where deep-reach ball-nose profiling is required. The 1.5-inch length of cut accommodates deep-cavity work, and the 4-inch overall length provides clearance in tall-workpiece setups. The 0.25-inch diameter and matching shank allow direct installation into standard 1/4-inch collets and end mill holders without adapters. Typical applications include die and mold work, sculptured surface finishing, and contour passes in aluminum, steel, and hardened alloy workpieces.

Key Features

• Micrograin solid carbide substrate for superior hardness and wear resistance
• TiCN coating reduces friction and increases surface hardness for extended tool life
• 40-degree helix angle promotes efficient chip evacuation in deep-pocket cuts
• 3 right-hand spiral flutes for balanced cutting forces and smooth finish
• Extra-long 1.5-inch length of cut enables deep-cavity and deep-wall profiling
• Single-end ball nose geometry suited for 3D contouring and radius-bottom slots

Compatibility

Designed for use with standard 1/4-inch collets, end mill holders, and shrink-fit toolholders common to CNC machining centers and manual vertical mills.

Installation Notes

Install into a clean, burr-free collet or end mill holder and torque the retention nut to the toolholder manufacturer specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on a three-flute tool. Power down the spindle completely and lock it out before changing or inspecting tooling. Do not exceed the tool manufacturer recommended depth-of-cut or axial engagement for the workpiece material to avoid deflection or breakage in the extra-long reach configuration.
