What does 8 TPI mean on a saw blade?
TPI is an acronym for Teeth Per Inch and is a common measurement to be detailed on saws. As a general rule, the more teeth per inch a saw has, the neater the finish will be, but the slower the saw will cut. The fewer teeth per inch, the faster the saw will cut but the rougher the finish will be.
What does the number of teeth on a saw blade mean?
Number Of Teeth In general, blades with more teeth yield a smoother cut, and blades with fewer teeth remove material faster. This type of blade will usually have 60 to 80 teeth, and the higher tooth count means that each tooth has to remove less material.
Why do circular saw blades have different number of teeth?
Standard Circular Saw Blades 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. Smaller gullets separate the teeth. Combination blades can make both rip cuts and crosscuts.
What is the best TPI for cutting wood?
If you’re looking to cut wood or other soft materials, you’ll need a blade with a TPI of 6 up to 20. For harder materials like metal, a TPI between 14 up to 36 is more suitable.
How many teeth should I have on my saw blade?
Combination: 10-inch blades with 50 teeth and 12-inch with 60 teeth. 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.
What saw blade to use for ripping?

How many teeth does a hollow ground saw have?
Crosscutting blades have from 80 to 150 teeth. The more teeth the blade has, the smoother the cut will be.
