Small Hole Gages & Sets
Half Ball with Flat Bottom
• Ideal for accurately measuring the most shallow holes,
slots and recesses.
• Hardened half-ball measuring surface with two-point contact.
• Radius on each gage is less than the minimum diameter
to be measured, which provides the two-point contact
necessary for maximum accuracy.
• The adjustment of the gage beyond their range is
restricted by a safety stop that prevents breakage.
• Set supplied in protective pouch.
