Detailed Product Description
Sunnen Model PG-800 Precision Hole Gage
The Sunnen Model PG-800 reads out actual size, taper, out-of-round and bellmouth. The overall range of this instrument is divided into two sub-ranges, one on either side. The direct reading scales have a range of .005" divided into increments of .000050". The gage points are round, replaceable carbide "doughnuts" which can be rotated for long wear life. Gaging pressure at mid-scale in four ounces. A sliding face plate equipped with adjustable stops permits end-to-end examination of bores right up to the edge. These stops can be set to allow examination of any particular section or portion of a bore when necessary. Adjustable flags on the gage face clearly define the specified tolerance so that in repetitive gaging, one glance at the scale is enough to tell if the piece is in or out of limits.
