Designed for mini lathe users, this mini hollowing set consists of four modular parts: (1) A golden solid, aluminum, and knurled handle (5 5/8" length, 1" dia. with two Allen screws). The handle is equipped with a sleeve, which enables it to accommodate tools with 3/8" and 1/4" shanks. (2) A 3/8" boring tool for depth drilling. (3) A 1/4" round nose scraper for hollowing out in initial stages. (4) A 1/4" swan neck hollowing tool for widening out the shoulder areas. The length of the cutting tools (all made of high speed steel) is about 5" which makes the overall length of the tool with the handle about 9". The set is great for making small goblets, boxes, and jars. Sold in a plastic pouch.
