These special 25mm extended jaws are designed to act like a pin chuck – expanding into a pre-bored hole.This is an especially useful technique for free form edge bowls. A real big advantage over Pin Chucks though is that you don’t have to bore to an exact size – any size between the minimum and just under the maximum expansion will do.The longer jaws allow for a very powerful spigot grip for all smaller work like lace bobbins (up to 6″ in length) and delicate pots etc. The jaws also have a dovetail to mount small bowls (up to 6″ dia).Jaw Travel Range Table Imperial (Inch)Jaw Set & Chuck SuitabilityExpanding Action SpecificationsContracting Action SpecificationsJaw SetSuitable ChuckSquare StockSpigot ModeMinMaxMinMaxMinMaxPIN JAWPrecision Midi*1.0241.3780.2760.6690.3940.748Nova G31.0241.8110.2761.1020.3941.220SuperNova21.0241.8110.2761.1020.3941.220Titan1.0242.2440.2761.4960.3941.614Metric (mm)Jaw Set & Chuck SuitabilityExpanding Action SpecificationsContracting Action SpecificationsJaw SetSuitable ChuckSquare StockSpigot ModeMinMaxMinMaxMinMaxPIN JAWPrecision Midi*26357171019Nova G326467281031SuperNova226467281031Titan26577381041Please note, Tolerance of /-1mm on all measurements* Measurements with stop-screw** Recommended with Caution
