7/16″ 22mm R8 Shank Milling Arbor Cutter Holder + 8 Gear Cutters

Description

Product Overview

The 7/16″ 22mm R8 Shank Milling Arbor is engineered to deliver exceptional rigidity and accuracy for gear machining tasks. Constructed from high‑grade steel, the arbor features a solid R8 drawbar that securely clamps the cutter holder, minimizing deflection even at high spindle speeds. The accompanying set includes eight DP16 involute gear cutters, numbered 1 through 8, each with a 14.5° pressure angle and a 22mm bore. Precision grinding technology ensures that tooth profile errors are kept to a minimum, providing smooth meshing and high transmission efficiency. The package dimensions of 11.02 x 3.54 x 2.36 inches and a weight of 3.28 pounds make it easy to store and transport while maintaining durability for demanding CNC lathe operations.

Usage

This arbor and cutter set is ideal for a variety of CNC lathe applications, including gear prototyping, small‑batch production, and maintenance of existing gear trains. The 22mm bore matches standard lathe spindles, allowing quick installation without additional adapters. Users can select the appropriate cutter number based on the required gear size, ensuring precise tooth geometry for both internal and external gears. The robust design tolerates high cutting speeds, making it suitable for aluminum, brass, and mild steel workpieces. Whether you are a hobbyist building custom gearboxes or a professional machinist fabricating components for automotive or industrial equipment, this kit provides the flexibility and reliability needed for consistent results.
