INSIZE 6312-80 Setting Ring Ø80mm

Use the INSIZE 6312-80, a Ø80mm setting ring (ring gauge), to zero-set inside micrometers, three-point internal micrometers and bore gauges before measuring. INSIZE finishes it to DIN 2250-1:2008 Type C standard accuracy, keeping roundness and taper within 0.8 µm for this diameter. A marking line on the face marks the checking direction, and since the actual size can vary from the ordered size by as much as ±10 µm, INSIZE engraves the true diameter on the ring so it can be read directly. Every ring comes with INSIZE's own inspection certificate.
