INSIZE 6549-1 Right Angle Plate 150x63x150 mm

INSIZE's 6549-1 right angle plate is a 150x63x150 mm block of tool steel, hardened to HRC56-58, used to hold a workpiece square to a machine table or surface plate during marking-out, inspection or light machining. INSIZE holds the parallelism between its faces to within 3 micrometres and the squareness to within 5 micrometres, so opposite and adjoining faces can be trusted as true right angles. Both faces carry a grid of tapped mounting holes, letting you bolt a workpiece or fixture directly onto the plate instead of relying on clamps alone.
