Pattern: Sixteen (16) sets of circles:
Drill and tap size measurements to include:
M1.0 to M7.0. Outer diameter of tap gauge indicates nominal thread O.D.
Reticle is Low Reflection Chrome on a stable glass substrate. The pattern is on the contact surface, right reading looking through.
The Reticle Pattern is very durable, double layer, deposited evaporative Chrome/Chrome Oxide, for a reflectivity of less than 5% looking at the pattern. The Patterns on all Reticles manufactured by Max Levy are replicated from Precision Chrome on Glass Tooling under clean room conditions.
