This heavy duty industrial angle vise is exceptionally robust for demanding angular applications. The body is calibrated from 0º to 90º in 5º graduations for precise angle drilling without the use of blocks or wedges. Two knurled socket-head bolts with lock washers on each of two thick side plates allow quick hand-tightening and secure wrench fastening to ensure solid locking in all positions. The fixed jaw is grooved; the removable base swivels 360º (1º graduations) and can be fastened in place with two bolts.
