Key Features of the Wen scroll saw 3921

Rip capacity

The scroll saw has a capacity of 2inches vertical and 16inches in the throat. The tool has the rip capacity of working on large pieces of wood depending on the type of blade you are using at a specific angle.


You choose the blade you want to use between the pinned or pinless use in the standard direction. A pinned blade is swapped on the 90 degrees as you allow cuts to move across the table. That defies the standard way of moving back and forth, increasing the cutting capacity. The blade holder holds any blade. 


The table is spacious, and you can work on large wood pieces. It is 16 x 11inches. You can place your tools, not in use, onto the table. The table bevels up to 45 degrees for an angled cut. 

Air pump

The function of the pump is to clear sawdust from your work area. That gives you a clear line of vision as you cut your wood piece. It works hand in glove with the 1-1/2 inch dust port. The dust port makes sure that the environment is clean.  

Rotations per minute

The motor has the power to produce 550-1600 strokes per minute. That is called speed variance. Speed depends on the type of blade and the thickness of the material you are working on.
