Starrett - Slide Calipers

This extremely handy caliper gives direct readings of both circumference and diameter in a single setting.

• Especially useful for obtaining instant circumference and diameter measurements of rope, cordage, metal rods, pipe, tubing, etc.
• Also for checking cutting speeds on lathe work. (Rule: Cutting Speed in Feet per Minute = Circumference divided by 12 x Revolutions per Minute.)
• The upper edge of the slide is graduated from 0 to 11 circumference inches in 16ths and the lower edge from 0 to 3 1/2" standard measurement in 32nds
• The jaws are 1 3/8" deep and therefore will caliper a cylinder up to 2 3/4" diameter
