The most common blade diameter is
7-1/4 inches
. Most saws with blade capacities of 6 inches or more can cut through 2-inch dimensional lumber at a 45-degree angle in a single pass. A 5-3/8-inch saw can cut through 2-inch dimensional lumber in one pass at 90 degrees but requires two passes at 45 degrees.
What size blades do circular saws use?

71⁄4-inch-diameter blade
and a motor that draws 8 to 15 amps of power.
What are the most common saw blades?

What are three common circular saw blades?
Cold saw for metal
There are three common types of blades used in circular saws;
solid-tooth, segmental tooth, and the carbide inserted-tooth
. The circular saw is typically fed into the workpiece horizontally, and as the saw advances into the material, it severs the material by producing narrow slots.
Is more teeth on a saw blade better?
Standard circular saw blades are typically used to cut wood or wood composites. The number of teeth on the blade helps determine the speed, type and finish of the cut. Blades with fewer teeth cut faster, but those with
more teeth create a finer finish
. … Combination blades can make both rip cuts and crosscuts.
How do I choose a circular saw blade?
Generally, blades with more teeth will provide a smoother, finer cut whereas blades with fewer teeth will provide a rougher cut. The benefit of fewer teeth is faster cutting and a lower price. For most construction work, a
24-tooth general use blade
is sufficient.
What is the hardest hacksaw blade?
Manufactured entirely from M3 material,
Starrett Redstripe power hacksaw
blades are hardened throughout and able to consistently cut the hardest material.
How many teeth blade for ripping?
Ripping: 10-inch blades with
24-30 teeth
and 12-inch blades with 40 or fewer teeth. Crosscutting: 10-inch blades with 60 teeth and 12-inch with 80 teeth.
How long do circular saw blades last?
They can last
between 12 and 120 hours of continuous use
, depending on the quality of the blade and material they’re used to cut.
Are there different blades for circular saw?
There are different types of blades
, but the circular saw blade types are flexible tools. They can make different kinds of concrete, plastic, metal cuts and wooden materials. However, for a circular saw to be perfect for the project that you’re working on, you need to choose the right blade.
What are the three types of blades?
For cutting wood, circular saw blades are available in three primary styles:
rip, crosscut, and combination
. The distinction is based on tooth form and gullet size. For ripping, teeth are flat-topped and gullets are deep.
Can you put a dado blade on a circular saw?
You can use stacked circular-saw blades to cut dadoes on a
tablesaw, Les, as we confirmed in the WOOD® magazine shop, but your dado cut quality will suffer. To make circular-saw blades cut even rough dadoes, you’ll need blades of the same brand and model to avoid minor differences in diameter.
Which saw blade makes the smoothest cut?
With fewer spaces between the teeth,
crosscut blades
remove less material, resulting in a smoother cut. It also means it takes these blades longer to move through wood. Crosscut blades are an excellent choice for finish carpentry and other applications that require precision and a smooth finish.
What is the space between two protruding teeth on a saw blade called?
Gullet
– The gullet refers to the space between each tooth on the blade. A wider gullet produces a bigger chip of material cut.
Why does my saw blade burn the wood?
A dull blade will make it hard to cut quickly, and the slower the feed rate of the saw, the more friction against the wood and the greater the likelihood of scorch marks.
Pushing the stock through the saw too slowly
is a common cause of saw blade burn. Sometimes a blade that feels dull might only be dirty.
What is the best circular saw blade for cutting MDF?
Straight Cuts
Any circular saw or handheld cutting tool will make rip cuts or crosscuts in MDF, but the blade should be
carbide-tipped
, because the high glue content of the material dulls steel blades quickly.
