INSIZE 4194-3S Carbide Pin Gauge Set 2.00–3.00 mm

INSIZE's 4194-3S pin gauge set spans 2.00–3.00 mm in 101 carbide pins, each 0.01 mm apart. INSIZE rates the set to DIN 2269, grade 1 and ±1 µm diameter accuracy; the pins are carbide, hardened to HRA90-90.5. The pins measure 50 mm in length and come housed in a lined wooden case for storage. The carbide construction holds its size under frequent handling, so this set suits high-volume hole and bore checking where pins are used many times a day.
