The WEN 3630 is the heaviest hitter in this roundup, built around a 10 amp motor that the maker says handles up to 4-1/2 inches of wood and about 3/5 inch of metal. A bigger motor matters in a reciprocating saw because the blade changes direction thousands of times a minute, and each reversal costs energy; a motor with reserve keeps the stroke rate up when the blade bites into a wet stud.
The head pivots to eight stops, one every 45 degrees, so you can reorient the shoe and the blade to cut flush against a wall or floor. The pressure-sensitive trigger gives 0 to 2800 strokes per minute, which means you can feather a start in thin metal and then push through. Compared with the Craftsman's 7.5 amps, the WEN has a third more current draw, and against the SKIL it shares the same type of design with more motor.
A saw this size vibrates hard, so use both hands and keep the shoe against the work. Check the brushes after a few demolition jobs, and replace blades when the teeth round off, because a dull blade turns into a heat source. Carry a spare set of demolition blades with thick bodies, because a flexing thin blade wanders and snaps when it hits a nail at full stroke.
What works
- 10 amp motor has the most reserve in this roundup
- Pivoting head with eight stops allows flush cuts in corners
- Pressure-sensitive trigger gives 0 to 2800 strokes per minute
- Rated for wood up to 4-1/2 inches thick
Watch out for
- Heavier and more vibration than the 7.5 amp saws
- Corded design needs an outlet or extension cord
- Brand support is thinner than a major tool name
