Intended to seat and expand within a minimum 25mm (1") diameter by 50mm (2") deep bore, these jaws are particularly valuable for holding large freeform blanks. Specially designed for green wood, the exterior jaw faces have a deeply grooved pattern for a firm hold.

They have an internal capacity of 0" to 1 3/16" and an external capacity of 1 3/16" to 1 31/32" when used with the K10 chuck, and a 0" to 2 3/8" internal capacity and 1 3/16" to 3 5/32" external capacity when used with the Goliath chuck.
