Economy Depth Gauges
Take precise depth measurements in small holes and slots. These gauges have a blade with wear-resistant etched markings.
Rod measures recesses where the ruler blade won’t fit.

Starrett Depth Gauges
Reach deep into small holes and slots for precise depth measurements. This gauge has a rod to measures the depth of recesses where the blade won’t fit. The blade has a hook which grabs the edge of an object for easy alignment. Markings are etched for wear resistance.

Mitutoyo Vernier Depth Gauges
These gauges have two scales for fine adjusting—a main scale and a sliding vernier scale. The vernier scale takes the space between graduation marks on the main scale and divides them into smaller increments for an accurate depth reading. Use the adjustment screw on the vernier scale for fine tuning. Designed for durability, these analog gauges are good for measuring the depth of small holes and slots in machine shops where they’ll get frequent use. They are often used to set the cutting depth for milling tools and counterbores.
Gauges with a hook end can measure the depth of lips, grooves, and other projected or recessed features that a gauge with a straight end could not access.

Starrett Depth Micrometers
Measure the depth of holes, slots, shoulders, and projections by changing out the steel extension rods supplied in 1" incremental lengths. The thimble has a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening.

Starrett Depth Micrometers with Calibration Certificate
These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Change out the steel extension rods supplied in 1" incremental lengths to measure the depth of holes, slots, shoulders, and projections. The thimble has a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening.
