The sharpness of a blade can greatly impact the quality of a cut. Dull blades are much more likely to scorch and burn wood because the teeth are not cutting the wood fibers effectively. A dirty blade can also affect the cut. As wood pitch builds up on the surface of the blade, it will be more likely to bind up and scorch the wood.

Keep your saw blades clean to ensure smooth cutting. Manufacturers offer different types of blades for different types of cutting:. As a general rule, woodworkers should have several different blades on hand for each saw they own.

For instance, with a inch table saw , it's a good idea to have a tooth blade for general purposes, an tooth blade for plywood and veneers, and a specialty ripping blade for making rip cuts. On a band saw , keep a few different thickness blades, making your choice depending on the sharpness of the curves being cut.

Blades for circular saws come in the same options as are available for table saws—fine-tooth blades for precision cross-cutting, a coarser blade for rip-cutting, and a combination blade for all-purpose framing carpentry. A good blade set for a saber saw or jigsaw will include coarse-tooth blades for quick cutting and rip cuts and fine-tooth blades for smooth crosscuts.

Specialty jigsaw blades are also available for cutting ceramics, plastics, and other materials. Actively scan device characteristics for identification. Use precise geolocation data.
