Description
Gear Tooth Vernier Slide Caliper, 0-25mm
The Starrett No. 456 Gear Tooth Vernier Caliper is designed to measure in 0.001 or 0.02mm the thickness of gear teeth at the pitch line (the chordal thickness of the teeth) using the distance from the top of a tooth to the chord. For the same purpose, it can also be used for measuring hobs, form and thread tools, etc. The thickness of a tooth at the pitch line is measured by an adjustable jaw after the addendum is set by the adjustable tongue. Each of these is adjusted independently by screws on the graduated bars.
