Sorby Excelsior Internal Scraper Cutter is a high-performance tool designed for the connoisseur wood turner and those who frequently work with hard woods. This internal scraper cutter features a high-speed steel construction enhanced with a Titanium Nitride (TiN) coating, which dramatically increases its edge holding ability and tool longevity. The full round tip is i for hollowing vessels by shear scraping and can be repositioned multiple times before requiring re-sharpening, which is easily done by honing on the top face. With a 5/8" diameter and a Rockwell hardness equivalent of 80, this cutter outlasts standard tools by four times and performs popular cryogenically treated and powdered metal turning tools. The TiN coating also reduces friction between the tool and wood, making it especially effective when working with extremely hard or abrasive woods and knotted burrs. This means you can spend more time turning and less time sharpening, ensuring an efficient and enjoyable woodworking experience. Made in England, the Sorby Excelsior Internal Scraper Cutter combines durability, precision, and ease of use for superior woodturning results. Model Number: B826GC
