Overview
The SKILSAW SPT77W-01 is a 7-1/4 inch worm drive circular saw with the brand's original aluminum housing, weighing 14.2 pounds. It targets framers, deck builders and remodelers who value gearbox torque and a left-blade sightline over a lighter sidewinder-style saw.
Worm drive gearing trades top-end RPM for torque at the blade, which helps the saw push through wet framing lumber or engineered sheet goods without bogging down. The rear-mounted motor shifts weight back in the hand, which matters most on long rip cuts. At 14.2 pounds it is not a saw built for overhead or ladder work.

- 14.2 pound aluminum housing
- Corded electric, built for daily jobsite use
- Left-blade orientation
Who it's for
Professional framers, deck crews and remodelers who run a circular saw for hours a day and want sustained cutting torque. Occasional DIYers who only need a saw for the odd home project will find it heavier than necessary.
Pros and cons
- Worm drive torque suits thick or wet framing lumber
- Rear motor placement balances the saw during long rip cuts
- Left-blade layout gives a clear cut-line view for right-handed users
- 14.2 pounds makes overhead or ladder cuts tiring
- Corded design means no cordless option on this model
Performance notes
Worm drive gearing runs the motor parallel to the blade and reduces speed through a gear set, which raises torque at the blade compared with a direct-drive sidewinder saw. That reduction is what lets it hold cut speed in thick or wet lumber. The rear motor placement also moves the saw's balance point back toward the user's hand.
