The Bosch 1662K 18-volt circular saw uses its exclusive Bosch-built power train to deliver corded power in a cordless unit, with 3,600 rpm speed for fast cutting. The rear depth adjustment quickly matches the depth of stock for more accurate cuts. With a 50-degree bevel, the saw easily cuts 2-by material, and the 45-degree positive stop accurately adjusts the bevel for the most common cuts. The unit's integrated dust-collection port vacuums away up to 70 percent of sawdust for cleaner work areas. The saw comes with a 6-1/2-inch, 18-tooth, ultra-thin kerf carbide blade, which cuts smoother by reducing friction and drag, while the spindle lock allows faster, easier blade changes. Includes rip fence, one 18-volt battery, one-hour charger, and case.
