The Mitutoyo Series 511 Micrometer Head Bore Gauge is a highly accurate instrument suitable for measuring the diameter of holes. A carbide contact point provides high durability and wear-resistance while a large grip with a sponge-like structure reduces heat transfer from your hand, thereby improving measurement precision. The Mitutoyo Series 511 Micrometer Head Bore Gauge maintains its accuracy while providing a longer plunger stroke. Via the addition of sub-anvils, it supports a wide measurement range.
