This Axminster Woodturning Screw Chuck is compatible with the Dovetail Jaws Type E. Using a screw chuck is a quick and convenient method for a mounting a turning blank on your lathe. The central screw has a deep sharp thread for a positive and secure hold. It only requires you to drill a single shallow hole in the blank. Unlike a face plate which requires several screws to attach the timber, a screw chuck has a single central screw. It is ideal for smaller or shallow workpieces, (always assess the suitability for the size of the work). Made entirely in Axminster, UK.-bg
