Reciprocating saw blades let demolition crews cut hard, fast and dirty. Slam the blades into walls, and they rip through studs, nails and wiring. Crews forgo smooth cuts for speed, choosing blades with widely spaced teeth that tear wood apart. But the gaps can catch nails and snap teeth. Instead of narrowing the gaps, which can slow cutting, Milwaukee reshaped the teeth, adding small nodules that slightly project over the gaps to block nails. The result is a blade with virtually unbreakable teeth that cuts twice as fast.
