Two replaceable stainless steel parallel screw chucks which fit into either the 62mm recess of the A dovetail jaws, or the internal recess of the 100mm or 114mm C dovetail jaws. Particularly useful for the initial mounting of bowl blanks whilst the outer form and the dovetail base are being shaped. Once this stage is completed the woodscrew chuck can be removed and the bowl quickly mounted directly into the C jaws. Supplied with large screw (910466). Three sizes of threaded insert are available for all Axminster screw chucks requiring 4, 6.35 and 8mm drill sizes.
