Accupro 12184687 Ball End Mill 0.5512 in 4 Flute Carbide

Product Description

The ACCUPRO 12184687 is a single-end ball end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide, it delivers the hardness and wear resistance required for aggressive material removal and fine contouring. The cutting end measures 0.5512 inches (14 mm) in diameter with a 1.26-inch (32 mm) length of cut. An AlTiN (aluminum titanium nitride) coating provides elevated heat resistance and extended tool life when cutting ferrous alloys, stainless steels, and hardened materials. Four right-hand spiral flutes with a 40-degree helix angle promote efficient chip evacuation and a smooth cutting action.

This ball end mill is suited for CNC milling centers and manual knee mills performing 3D profiling, slotting, and contour work on ferrous and non-ferrous metals. The ball nose geometry makes it the standard choice for die and mold work, radius profiling, and blending operations where a flat-bottom tool cannot reach. It is a single-end design, meaning the cutting geometry is on one end only. The 14 mm shank diameter fits ER collet chucks, hydraulic chucks, and shrink-fit holders commonly used in production shops and tool rooms.

Key Features

• Micrograin solid carbide construction for superior hardness and dimensional stability
• AlTiN coating for high-temperature resistance and extended tool life in ferrous materials
• 4 right-hand spiral flutes with 40-degree helix for efficient chip evacuation
• Ball nose geometry suited for 3D contouring, radius profiling, and die and mold work
• Single-end design with matched 14 mm cutting and shank diameter for balanced rigidity
• Right-hand cutting direction compatible with standard CNC spindle rotation

Compatibility

Designed as a direct-fit replacement or production tooling option for CNC machining centers and manual mills accepting a 14 mm shank diameter via ER collet, hydraulic, or shrink-fit toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the toolholder to the recommended gauge-line depth before torquing the retention system. Inspect the cutting edges for chipping before each use and do not exceed the recommended depth of cut or feed rates for the workpiece material.
