The large handwheel (left) makes table height changes
effortless. The tool-free depth stop (right) makes sanding several boards to a precise thickness virtually automatic.
Table Height
A large, 7 ¾”-diameter cast-iron handwheel adjusts the table height within its 4” range. Each full turn of the handwheel changes table height by 3/32" for ultra precise sanding thickness control. The handwheel operates a screw and gear drive that controls both ends of the table to keep it level for maximum sanding accuracy.
An easy to use depth stop is built onto the support post and makes sanding many boards to a specific thickness fast, easy and very accurate. The depth stop is tool free so you can concentrate on sanding rather than finding a wrench!
Digital Read Out
The DRO (digital read out) comes pre-installed on the JET 22-44 Pro- 3 Drum Sander (#649600). This digital measuring device makes setting ultra precise sanding depths, or returning to one with 0.01” resolution simple and easily repeatable. The DRO can be set to display either inch or mm readings with the push of a button. The battery as well as a spare is supplied with the machine.
The DRO has several distinct functions. Probably the most commonly used function is the “Absolute Measurement”. Sand a piece of wood on the JET 22-44 Pro-3 Drum Sander, measure that thickness with digital calipers and then set the DRO to that dimension. You can then sand other pieces to match that thicknesses quickly with exceptional accuracy.
The included DRO
has several functions, not the least of which is allowing ultra precise table to drum settings.
The DRO also has a “Relative Measurement” that can show the amount of material to be removed from a previously sanded board. “Hold” records a setting so you can return to it later. “TOL” (tolerance) allows setting upper and lower tolerance limits. All of the functions and their setting procedures are fully described in the instruction manual.
A gamut of great features including an extra powerful 3-HP motor, large capacity conveyor with infeed and outfeed tables and the precision of a dead flat table, balanced aluminum sanding drum backed with a DRO height adjustment system. As well the JET 22-44 Pro-3 comes equipped to be mobile with heavy duty double locking casters. The JET 22-44 Pro-3 is a great machine for anyone tackling jobs that require large pieces to be sanded from the hobbyist woodworker to the small job shop.
