The S78MXTBZ Bore Gage features extended travel, reducing the need to exchange anvils. The ground contact points seat the internal micrometer faster and more accurately than the spherical contacts found in other gages. The rugged and accurate 78MXT series internal micrometers are available individually or in economical sets from .080-12″ (2-300mm).
Designed to measure internal cylindrical holes and grooves, this gage can measure in metal, plastics, and other materials. The S78MXTBZ features a 2-point contact with a hardened point to ensure accurate measurements. This set comes with 3 interchangeable heads and 2 rings.
