SKILSAW SPT77WML-01 15 Amp 7-1/4 In. Magnesium Worm Drive Circular Saw

A worm drive saw uses a specialized gear mechanism where the motor is positioned at a right angle to the blade, transferring massive torque to the blade. This makes the SPT77WML-01 incredibly powerful and ideal for heavy-duty framing and plunge cuts.

Despite having a heavy-duty 15-amp motor, the saw weighs only 11.5 pounds. This surprisingly light weight is achieved by utilizing magnesium components in the housing, which significantly reduces user fatigue on the job site.

It is designed to use standard 7-1/4 inch diameter blades for cutting thick wood and plywood. The saw features a 53-degree bevel capacity, allowing users to make highly aggressive angled cuts.

Yes, because worm drive gears require continuous lubrication to prevent them from burning out, it features an easy-to-view oil site glass. Users must regularly check this window to ensure the gears are properly bathed in oil.
