An illuminating device for determining the dimensional integrity between a first and second material working tool including a light emitting element connected to a light transmitting element, the light transmitting element having angularly oriented light emitting surfaces for directing emitted light from the light emitting source element in a direction toward the first material working tool, and then through the second material working tool to give a substantially 360 DEG reflected light illumination in a clearance area defined between the first and second material working tools.
