Three thousand strokes per minute. Fifty strokes per second. One stroke every 0.02 seconds. Such category-topping speeds let this little hummingbird saw through particleboard, PVC — even galvanized pipe — with insatiable force. The ergonomics are also top-notch: Bosch's slick locking system means you can replace blades with one hand. But the real news is the 36-volt battery — among the first to use Li-ion cells, which translates as more consistent power throughout the charge and a lifespan that shreds the competition by 25 percent.
