The Small Hole Gages are ideal for accurately measuring small holes, slots, grooves, and recesses. This makes it perfect for general work where more accurate measurement is required.

These gages have a precision ground radius on each gage that provides two-point contact for maximum accuracy and a hardened-ball measuring the surface with two-point contact.

Measuring Ranges:

3mm - 5mm (0.118" - 0.197")

5mm - 7.5mm (0.197" - 0.295")

7.5mm - 10mm (0.295" - 0.394")

10mm - 13mm (0.394" - 0.512")

They are designed with a smooth and sensitive adjustment that makes it easy to get the perfect fit. The adjustment range is also restricted by a safety stop, preventing breakage and damage. Furnished in plastic case
