Sorby Brass Ferrule, 19 mm is crafted from high-quality solid brass, the same material Robert Sorby uses for their handled turning tools. This ferrule is for woodturners who want to custom-make their own handles or replace an old one with a durable and reliable component. The ferrules come either annealed or hardened, with one inside edge beveled to make assembly easier. Measuring 3/4 inch (19 mm) in outer diameter and length, and made from 23 gauge brass, this ferrule combines precision and strength to enhance your turning projects. Model Number: HF19B
