JK how many RPM'S does the 4000 have for NO load,,,,3600 or so ?

The New Bosch GTS1031 has 5000 RPM'S NO load....She's a screamer but has a 18" limited ripping Capacity. Yours probably has 29/30"

In my opinion if you want to Fly Coach get a Bosch. If you want to FLY 1st Class with the Big Dogs go with Delta or Jet.

Just a heads up Delta was sold off from Stanley/Black&Decker to a Tiawan-Ezee company in 2011.Who knows what the future/quality of the tools will be in the end. When Delta was owned by Pentair there tools were the best in the Industry. Reel WORK HORSES.
