dorkster,
Precision Instruments made most of Snap Ons torque wrenches until around 2002, when Snap On acquired CDI Torque products.
It appears CDI makes all of Snap Ons micrometer torque wrenches now.
Precision still supplies the 3/8 split beam wrench for S.O., but the 1/2" split beam is made by someone else....odd.
It looks like S.O. dial wrenches are also still made by Precision Inst..
The Snap on electronic Tech wrench is made overseas by some Asian company.
So.....one can buy a CDI or Precision Instrument wrench much cheaper than a Snap On. The main difference will be that the Snap On version will have a S.O. ratchet head while the others will have their own ratchet head. The internal torque mechanisms are the same according to the company techs. I spoke with.
CDI, Precision Instrument, and Sturdevant are probably the three top torque wrench manufacturers in the US. A Danaher owned company in South Carolina (forgot the name) make wrenches for Sears, Armstrong, NAPA, and a host of other Danaher companies.
