End grain hollowing tools designed for hollowing small and miniature work, using branchwood or end grain timber. The smallest (850H) is designed to work through the narrowest of apertures, down to as small as ⅜" (10mm). The boring bar and depth stop (852H and 853) form an ideal method of quickly opening up a vessel to provide both entry opening and final hollowing depth. Where space permits the larger tool (851H) provides a heavier section and has the benefit of a replaceable swivel cutting tip. This can be used in conjunction with the wall thickness gauge (854) to create consistent side wall thickness.
