Description
The Starrett 829B is a full-ball small hole gage for general work, with a stated range of .200-.300 in (5.1-7.6 mm) and an overall length of 3 in (80 mm). It is used to measure small holes, slots, grooves and recesses.
Per the manufacturer, the hardened-ball measuring surface has a precision ground radius that gives two-point contact, adjustment is smooth and sensitive, and a safety stop prevents adjustment beyond the gage’s range. The hole size is transferred to a measuring tool such as a micrometer (not included). Sold as a single gage, not as the S829EZ set.
