The 78XT Series Internal Micrometers feature
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.
These rugged and accurate internal micrometers
are available individually or in economical sets
from .040-12" (1-300mm).
Wide measurement range without changing anvils
Resolution from .0001" (0.0025mm) on the 2-point contact tools ranging up to 1/4" (6mm) and .00025" (0.005mm) on the 3-point contact tools ranging from 1/4"-12" (6mm - 300mm)
Tungsten carbide measuring faces on all 3-point heads above 1/2" (12.5mm)
