Unlike most conventional hollowing tools, the unique Hollowmaster comes with a meaty ¾" flat surface. When laid on the tool rest, this gives ample support to prevent the tool being turned over by the rotation of the wood. You are not fighting the laws of nature but removing wood with ease. It's swan neck design means that the Hollowmaster can reach those spots that are often difficult to reach. The Hollowmaster comes with a swivelling hollowing cutter and a full round scraper cutter for fine finishing. Both are easily sharpened with a diamond file and can be replaced when need be. Instructions are included. The Hollowmaster is featured in "Robert Sorby Specialist Tools - Part 1".
