The DeWalt DW733S is a jointer planer combo (planer thicknesser) made by DeWalt until 1999. It’s the successor of the DW50 and DW1150, and is largely the same, but painted yellow instead of green. It was succeeded by the modern D27300.
It should not be confused with the DW733, which is a modern benchtop planer also made by DeWalt.
The main improvement over the older DW1150 seems to be a better dust hood, which helps with dust extraction, which was the main problem with the DW50 and DW1150.
Cast Alloy Body
Just like the DW50 and DW1150, the body is made from a heavy cast alloy, which makes it heavier and sturdier than similar machines like the Elektra Beckum HC260. This also meant it couldn’t really break easily, so most vintage machines I’ve seen are still in good shape.
The tables of the DW733S fold upwards, and lock in place with a spring to prevent falling down and smashing your fingers. This not only allows you switch quickly between jointing and planing, but it also means you don’t lose your table’s settings and keep your jointing table accurate.
There is also an optional mortising attachment that can be mounted on the side.
Replacement Blades: Blades for the DW1150 and DW50 might also fit the DW733S. You can find some here on eBay.
