Our new pin jaws have been improved by squaring the external shoulder to allow workpieces to properly register against the back of the jaws. This is ideal for use in expansion, to grip tubes in work pieces such as pepper or salt grinders. We have also reduced the internal diameter to 9 mm, making it ideal for making finials or lace bobbins - Thereby increasing its versatility. This set is ideal for miniature turning and to grip workpieces internally without excessive damage or marking.
Expansion: 25 - 45 mm
Contraction Spigot: 9 - 28 mm
Contraction Square: 7 - 27 mm
