Best Circular Saw Black Friday Deals 2022– Guide
One obvious difference between round saws is that the size of their blades. Each uses a particular size blade, from as little as 1/2-inch to as big as 16-5/16 inches. The range is pretty extensive, but the average person can get most framing and building tasks performed with a 7-1/4-inch model.
The tooth-count, or the amount of teeth around a blade, is the determining factor to what jobs a blade works best for. The lower your tooth-count, the rougher the cut will be, making the blades suitable for framing or demolition. Higher-count blades should be used for cabinetmaking, plywood, and finish work.
Pro tip: Circular saws cut on the”upswing,” meaning that the cutting half of the blade (the component under the shoe) spins towards the front of the saw. This will inevitably cause tiny slivers of wood to”tear out” of their timber –especially when cutting plywood–creating noticeably rough edges that detract from the quality of work. To minimize tear-out, lay a piece of painters’ tape over your cutline to maintain these fibers in place. You can even cut on wood face-side right down to eliminate tear-out concerns on the surface of the wood.Amperage refers to the a
mount of electric power a motor can withstand with no inner components failing. In the past, electrical motors were poorer and not as competent, therefore amperage was a significant specification to reconcile. Listing amperage has become somewhat of a tradition, as it’s still emblazoned across most circular saws’ packaging, though these times, nearly all electrical circular saws utilize 15 amp motors.
A saw’s speed, however, can be a consideration, since the faster the blade spins, the faster it can cut through a substance. But rates are normally comparative, because a 15-amp motor can spin a 7-1/4-inch blade quicker than it can spin a 10-1/4-inch blade. Generally speaking, when it comes to 7-1/4-inch saws, rates between 5,000 and 5,500 RPMs are common and must be adequate for quick, precise results.
Keep in mind that blade speed has nothing to do with the density of material a saw can reduce. This is largely determined by the blade type and quality.
Corded vs. Battery Power
As with any power tool, corded circular saws tie you to the electricity supply (i.e., an electrical socket) whereas battery-operated models can go anywhere. On most professional job websites, cordless circular saws are shunned in favor of corded components –and there’s historical basis for this bias. When battery-powered circular saws hit the current market, they were far inferior to a fantastic corded option in both speed and power. They also went via battery life very fast and would jam as soon as the blade felt any immunity.
Today’s battery-operated versions, however, have much more power and much longer battery life. Much of this improvement is due to the adoption of brushless motors (the latest, most efficient technology that is also maintenance-free) and lithium-ion batteries. For a DIYer who tends to tackle jobs beyond the shop, a new battery-powered alternative can’t be overcome. But corded versions still rule if you’re going to be using the saw all day . After all, an extension cord is always available, and there’ll be no downtime for charging batteries
