We put 28 of the leading 10" models through rigorous trials in search of the perfect "do-everything" blade. Changing tablesaw blades ranks right up there with changing speeds on a drill press or lathe: We know certain cuts call for specific blades for peak performance, but still, we don't always take the time to make a switch. Here's what you can learn from our testsEven the best blade will not perform well in a saw that's not properly adjusted. Many of the tested saw blades yield clean cuts on the top face of melamine-coated particleboard, but only one produced chip-free cuts on both the top and bottom faces of melamine (using a standard tablesaw throat plate and a slow feed rate).
Learn the complete results of our testing of all 28 blades in the May 2008 issue of WOOD magazine. I used to have an older table saw and I found the stabilizers worked well, but, I replaced it about two years ago with a RIDGID 10 inch table saw with the motor enclosed within the body.
My table saw and radial arm are used for everything from ripping cherry for table tops to ripping pressure treated for outdoor lumber.
You can have the biggest, best table saw on the market but still get lackluster or even lousy cuts if the blade is mediocre or wrong for the job.
Making smooth, safe cuts with your table saw, radial-arm saw, chop saw or sliding compound miter saw depends on having the right blade for the tool and for the type of cut you want to make. Forrest's Duraline blade series includes a 60 tooth tenoning blade that strives to make cutting tenon joints even easier. Perhaps no tool gets more heavy-duty use in the shop than the table saw blade, so having a good one is key, and AJ Hamler put the top seven to work.
If your table saw blade begins to wobble, it is experiencing something called table saw runout, there are several steps to determine the cause and how to fix it. Freud's ever expanding saw blade collection introduced new blades in 2011 for almost every workshop tool, including the growing number of track saws. Total Saw Solution's Micro-Kerf bade is dime thin, but provides surprising cutting power out of the smallest carbide blade on the market. Forrest's Woodworker II blade line continues to expand, including thin kerf blades that upgrade older and underpowered saws to full cutting strength.
Cut the plywood base a few inches wider and longer than the base of your saw, and then cut a 1-sq.-ft.
Antikickback pawls: Attached to a tablesaw's blade-guard system, these spring-loaded metal plates with sawtooth edges work in conjunction with the splitter. Apron: A horizontal piece that supports the top or seat and connects the legs of a table or chair. Arbor: In a tablesaw, the threaded shaft on which the saw blade mounts and is held in place with a nut, shown right.

Auxiliary fence: A temporary (sometimes sacrificial) fence attached to a tablesaw rip fence or miter gauge, or to some other machine table, or protect a cutter or bit while providing full workpiece support, shown right. Blade runout: Runout in circular-saw blades is measured by the amount of side-to-side movement in the blade body. Blade guard: On a tablesaw, a plastic or metal shroud that covers the blade to prevent the saw operator from placing his hands in contact with a spinning blade. Bow: A warp in which the ends of a board or wooden member curve in the same direction away from the desired plane, usually along the length. Burl: A swirling, twisted figure in wood grain caused by growths on the outside of the tree or root.
Chip-out: Splinters of wood that break away from a workpiece during a cutting or shaping process, shown right. Counterbore: A stopped hole in a workpiece that allows you to set a screwhead below the surface of the wood.
Dado: A square-cornered channel cut across the wood grain, typically using a dado set or a straight router bit, shown right. Edge grain: Wood characterized by the growth rings being 45 or more degrees, preferably perpendicular, to the surface of a board.
Now you don't have to sweat those changes -- if you have a proven general-purpose blade on your tablesaw.
About half the blades improved noticeably on their bottom-cut performance when we used a zero-clearance insert.
Some of the blades have teeth with complicated grinds, so have your blades sharpened by a service with up-to-date computer-controlled grinding equipment that will duplicate the manufacturer's original grind. A 3-hp tablesaw on a 220-volt circuit has enough muscle to power a full-kerf blade through nearly any cut.
Often the blades that ship with table saws are serviceable, but you typically can get a big boost in performance by upgrading to an aftermarket blade.
Schmidt saw blades come in nine different types for use in most shop situations, with laser cut blade slots and vibration control for cleaner, quieter cuts. Plus you can quickly screw the plywood down to sawhorses, benchtops or other places you set the saw. Kickback happens when the part of the board between the fence and the blade gets pinched, and the blade, spinning toward you, catches it and hurls it back at you. Cut and clamp a block to the side of your rip fence and then position the fence the correct distance from the blade (the length of cut plus the thickness of the safety block). In the event of workpiece kickback, the pawls dig into the wood to prevent it from being propelled toward the operator, shown right.

The backer board supports the wood to prevent chip-out as the blade or cutter exits the workpiece, shown right. The device also prevents small cutoffs from being thrown toward the front of the tablesaw and the operator. Because hardwoods often sell in random widths and lengths, a board foot measures thickness, width, and length to determine the total volume of wood in the board.
While extremely handy for defining lumber needs, cutting diagrams can't account for grain variations in solid wood stock or sheet goods, or for defects in solid stock. In previous tests we found that 40-tooth general-purpose blades typically outperform 50-tooth combination blades with less scoring and quicker feed rates on rip cuts. We got even better results in birch plywood crosscuts, where a zero-clearance insert eliminated bottom tear-out with nearly every blade.
But if you're using a 110-volt saw, you'll find that a thin-kerf blade plows more easily through tough cuts. This simple base allows you to clamp or screw the table saw to sawhorses, which provide a wide foundation for added stability. Clamp the block so that as the workpiece enters the blade it's no longer in contact with the safety block. The gradual incline of the jig (about 12 degrees) helps guide sagging pieces and slowly bring them up as you push your board through the saw.
Be sure to screw the jig to the plywood base of the saw for stability (your saw base must be screwed or clamped to the sawhorses as well).
These parts of the tool work together to align a retractable circular blade that plunges into the mating joint members at the desired slot location.
So we rounded up 28 general-purpose blades (16 thin-kerf, 12 full-kerf) from 19 manufacturers and tested them in crosscuts and rip cuts in hard maple, melamine-coated particleboard, and birch plywood using 10" contractor- and cabinet-style tablesaws. Use your blade guard whenever possible and always wear safety glasses and hearing protection. This crosscutting method prevents the workpiece from binding between the fence and the spinning blade.
Pound in the carriage bolts, slip the saw over the bolts (use spacers if they come with the saw) and fasten the saw to the base with washers and nuts.
