Accupro 12184680 Ball End Mill 0.4844 in 4 Flute Carbide

Product Description

The ACCUPRO 12184680 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous metals, hardened steels, and similar materials. The 0.4844-inch (31/64) ball nose diameter and 4-flute geometry produce smooth contoured surfaces and 3D profile work with consistent chip evacuation. A 40-degree helix angle promotes efficient cutting action and reduced chatter. TiCN coating increases surface hardness and heat resistance, extending tool life in demanding applications. The single-end configuration delivers a 1-inch length of cut with a 1/2-inch shank diameter and 3-inch overall length.

This end mill suits CNC machining centers, vertical mills, and manual knee mills running general-purpose and finishing passes on mold cavities, dies, contoured part features, and slotting operations. The right-hand cutting and right-hand spiral flute direction make it compatible with standard spindle rotation. Micrograin carbide substrate adds wear resistance and rigidity in both roughing and finishing contexts where surface finish and dimensional accuracy are critical.

Key Features

• Ball nose profile for 3D contouring, profiling, and cavity milling
• 4-flute, right-hand spiral design for efficient chip removal and smooth finish
• 40-degree helix angle reduces cutting forces and chatter at higher feed rates
• TiCN coating improves hardness and thermal resistance for extended tool life
• Micrograin solid carbide substrate provides rigidity and edge retention
• Single-end configuration with 1/2-inch shank fits standard ER and side-lock toolholders

Compatibility

Designed for use in CNC machining centers and manual mills accepting 1/2-inch shank toolholders. No specific machine model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before loading or changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates edge wear and degrades surface finish on ball nose tools.
