Accupro 12184326 Ball End Mill 0.125 in 3 Flute Carbide

Product Description

The ACCUPRO 12184326 is a solid carbide ball end mill designed for precision milling operations in ferrous and hardened materials. Measuring 0.125 inches in diameter with a 0.5-inch length of cut and 1.5-inch overall length, this single-end tool is built for tight-tolerance profiling, contouring, and slotting work. The micrograin carbide substrate supports the TiCN coating, which reduces friction and extends tool life in abrasive materials. With a 40-degree helix angle and three spiral flutes in a right-hand cutting direction, it delivers efficient chip evacuation and a smooth surface finish in demanding applications.

This end mill is suited for CNC machining centers and manual milling machines where small-diameter, high-precision cuts are required. It is commonly used in die and mold work, aerospace component machining, and general precision metalworking. The 0.125-inch shank diameter matches the 0.125-inch cutter diameter, making it compatible with standard 1/8-inch collets and end mill holders. Machinists working with hardened steels, stainless steel, cast iron, and similar materials will find the TiCN coating and micrograin carbide construction well suited for production and prototype runs.

Key Features

• 0.125-inch ball end diameter for tight-radius contouring and profiling
• TiCN coating reduces wear and extends tool life in hard and abrasive materials
• Micrograin carbide substrate provides rigidity and edge retention
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Three right-hand spiral flutes for balanced cutting forces
• Single-end design with 0.5-inch length of cut and 1.5-inch overall length

Compatibility

Designed for use with standard 1/8-inch collet chucks and end mill holders on CNC machining centers and manual knee mills.

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 in the collet or tool holder to the recommended grip length and torque the retention mechanism per the holder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts to protect both the tool and the workpiece.
