Accupro 12184726 Ball End Mill 2mm 4 Flute Solid Carbide Altin

Product Description

The ACCUPRO 12184726 is a solid carbide ball end mill designed for precision milling operations in ferrous and hardened materials. With a 2.00 mm (0.0787 inches) cutting diameter and a 4-flute configuration, this stub-length tool delivers fine surface finishes in tight-tolerance applications. The 40-degree right-hand helix promotes efficient chip evacuation while maintaining cutting stability at high feed rates. An AlTiN coating increases surface hardness and thermal resistance, extending tool life in demanding cuts. Machinists and CNC operators working with die steels, hardened alloys, and aerospace materials will find this tool well suited to profiling and 3D contouring work.

This ball end mill is suited for use on CNC machining centers and high-speed milling machines where small-diameter, high-precision work is required. The 3 mm shank diameter fits standard ER collet systems and precision toolholders common in mold, die, and aerospace shops. The stub-length geometry provides rigidity for fine detail work in cavities and contoured surfaces. Single-end construction is standard for this class of micrograin carbide tooling.

Key Features

• 2.00 mm cutting diameter with ball-nose profile for 3D contouring and profiling
• 4-flute, right-hand spiral design promotes smooth cutting action and efficient chip evacuation
• AlTiN coating provides high thermal resistance and extended tool life in hardened materials
• Micrograin solid carbide substrate delivers rigidity and edge retention at small diameters
• 40-degree helix angle balances cutting forces and surface finish quality
• Stub-length, single-end configuration maximizes rigidity in precision milling setups

Compatibility

Designed for use in CNC machining centers with ER collet toolholders or precision shrink-fit holders accepting a 3 mm shank diameter. Suitable for milling ferrous metals, hardened steels, and similar materials where AlTiN coating provides thermal and wear benefits.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and in a locked or e-stopped state. Secure the 3 mm shank in a clean, properly sized collet or toolholder, ensuring full shank engagement per the toolholder manufacturer recommendation. Inspect the cutting edges and coating for chips or damage before each use, as micro-diameter carbide tools are sensitive to handling impacts. Tool runout should be verified with a dial indicator before production runs on critical features.
