Different types of circular saw blades are designed to cut different materials and work with different power saws. Make sure the blade you choose is suitable for the material you need to cut. You also need to make sure it fits your saw. There are several specifications you should check.
Look at the blade diameter and type and compare these specifications with the capability of your saw. Acceptable sizes vary by saw model, but in general:
- Handheld circular saws accept smaller blades, those 4-1/2 inches to 7-1/4 inches in diameter. These are typically carbide-tipped.
- Tile saws use 7-inch or 10-inch diamond blades.
- Table saws and compound miter saws use blades 10 inches or 12 inches in diameter. Like those for handheld saws, the blades are usually carbide-tipped.
- Metal-cutting chop saws, also called abrasive saws or cutoff saws, take 14-inch silicon carbide or aluminum oxide abrasive blades.
Check the size of the arbor hole (the hole in the center of the blade). It must fit the arbor or shaft on your saw. Many blades with a circular arbor hole include a piece you can knock out to allow them to fit saws with a diamond-shaped arbor.
Note the maximum RPM (revolutions per minute) rating of the blade to make sure it's compatible with the tool you plan to use.

Good to Know
Blade diameter, arbor hole size, number of teeth and kerf — the thickness of the cut the blade creates — are typically printed on the face of a circular saw blade. You may also see a list of appropriate tool types as well as maximum RPM and application specifications.
