The SKIL SPT70V-11 Corded 16-5/16 In. Magnesium Worm Drive Skilsaw is a heavy-duty corded circular saw built for cutting large dimension lumber and timber in a single pass. This is a circular saw designed for deep beam cutting, timber framing, and other full-depth cuts in thick wood stock. Model Number: SPT70V-11. If your work regularly involves 6x material, posts, beams, or thick framing members, this saw matters because it gives you the depth and power to finish the cut without flipping the material.

The headline spec here is the 6-1/4 inch cutting capacity. On the job, that means one-and-done cuts through 6x lumber up to 6-1/4 inches thick. That is the real time saver. Instead of cutting from one side, rotating the workpiece, and trying to meet the kerf cleanly, you make the cut once and move on. For timber framing, post and beam work, retaining wall timbers, and heavy outdoor structures, that is a big deal for both speed and accuracy.

Power comes from a 15 amp Dual-Field motor, and SKIL pairs it with a worm drive layout and brass worm drive gearing. The practical advantage is better pulling power in demanding cuts and a saw that is meant to live in thick stock, not just occasional oversized work. This is the kind of setup contractors and serious woodworkers reach for when standard 7-1/4 inch and even 10-1/4 inch saws start coming up short.

SKIL also built the saw around magnesium construction, including a durable die-cast magnesium footplate. That matters because a saw in this class needs to stay rigid and cut square, but it also needs to be manageable when you are guiding a large blade through expensive material. The magnesium build helps reduce weight compared to heavier all-metal alternatives while still giving the saw the stiffness and durability expected from a beam-cutting tool.

The 16-5/16 inch blade is included, so the saw is ready to go out of the box. SKIL also includes an electric brake, which is a practical feature on a saw of this size. When you are moving from cut to cut, setting the tool down, or working around staging and material stacks, faster blade stop time helps productivity and control. This is not a small convenience on a large circular saw. It is one of those features you appreciate more the longer the day goes.

Bevel capacity is listed at 0 to 45 degrees, which expands the saw beyond simple square beam cuts. If you are working on timber connections, angled braces, landscape structures, or heavy framing details, that extra range gives you more flexibility without moving to a different tool. The saw is also UL Listed, which is worth noting for jobsite compliance and buyer confidence.

Because this is a corded saw, there is no battery platform to buy into and no runtime tradeoff to manage. You get consistent power as long as you have the right power supply available. For shop work, site fabrication, timber processing, and repetitive cutting of large stock, that is often the better fit than cordless. It is built more like a dedicated production tool than a general-purpose grab-and-go saw.

Who should buy it? Contractors cutting posts, beams, and heavy framing members. Timber framers who need true one-pass depth. Remodelers and deck builders working with large treated material. Serious woodworkers and builders making outdoor structures, rustic furniture, and large custom assemblies. If you only cut sheet goods or standard framing lumber, this is more saw than you need. If you regularly cut 6x stock and want a purpose-built beam saw that saves time and cuts square, this is exactly the right tool.

SKIL SPT70V-11 Corded 16-5/16 In. Magnesium Worm Drive Skilsaw for Serious Timber Work

This is the kind of saw you buy when you are done pretending a standard framing saw can handle beam work efficiently.

• Who it's for: Pros and serious builders cutting 6x material, beams, posts, and other thick stock where one-pass depth saves real time.
