The SKILSAW SPT70V-11 is a 16-5/16 in magnesium worm drive circular saw with a 6-1/4 in cutting capacity, which SKILSAW calls the biggest worm drive saw on Earth.

In a timber frame shop that's the right size, not overkill: it crosscuts 6x timbers in a single pass, so there's no flipping the timber and no mismatched kerfs. The 15 amp Dual-Field motor drives brass worm gearing for the torque to keep the blade moving through deep cuts, and an electric brake stops it when you let go. The all-magnesium body and die-cast magnesium foot keep a saw this size manageable, and it bevels from 0 to 45 degrees for angled shoulders and rafter cuts. It comes with a 16-5/16 in SKILSAW blade, a saw stand and a multifunction wrench, and we stock the replacement blade.

SKIL began in 1924, when Edmond Michel and Joseph W. Sullivan started the Michel Electric Handsaw Company to make Michel's electric hand saw, first built in 1923. The company became SKILSAW Incorporated in 1926, which is where the saws got their name, and it brought out the Model 77 circular saw in 1937.
