SDT-100 Seat Depth Tool

The SDT-100 makes checking the seat depths easy and simple. SDT-100 enables the machinist to determine the valve seat depth in relationship to deck surface within .001" and without removing the pilot from the head while grinding the seat. The SDT-100 also reduces labor time in CC'ing the combustion chamber because of the accuracy of the valve seat depths. The SDT-100 is machined from extruded aluminum bar stock and has a precision 1" dial indicator. It is available in Sioux, Kwikway and Serdi pilot sizes. We can size our SDT-100 to any pilot size.
