How to find the right Saw Blades, Parts & Accessories AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Saw Blades, Parts & Accessories
- Diameter and arbor match
- Blade diameter must equal the saw's rated diameter, and the arbor hole must match the spindle exactly (5/8 in is standard on most North American circular, table and miter saws; some have diamond knockouts for worm-drive saws). Never ream or shim an arbor hole. A wrong-size bore lets the blade wobble or slip, which causes burning, kickback and failed blades.
- Max RPM rating
- The blade's printed maximum RPM must be at or above the saw's no-load RPM. An over-spun blade can crack or throw carbide teeth.
- Tooth count for the cut
- For 10 in table and miter saws: about 24T for ripping and framing, 40 to 50T for general purpose, 60 to 80T for crosscuts, plywood and trim. For 7-1/4 in circular saws, 24T for framing and 40T or more for finish work. Fewer teeth clear chips faster but cut rougher. More teeth give clean edges but feed slower and heat up in thick rip cuts.
- Tooth grind and hook angle
- Use ATB for crosscuts and plywood, FTG for ripping, and TCG for laminate, melamine and non-ferrous metal. Choose low or negative hook blades for sliding miter and radial arm saws. The grind determines tear-out and edge quality. A high positive hook on a saw that pulls through the work can make the blade climb toward you.
- Kerf width vs saw power
- Use thin-kerf blades (about 3/32 in) on cordless and lower-power saws. Full-kerf blades (about 1/8 in) suit 3 HP cabinet saws and saws with riving knives sized for them. A thin kerf reduces load and battery draw. A riving knife thicker than the kerf will bind the cut.
- Shank and interface fit (jigsaw, reciprocating, oscillating)
- Jigsaws take T-shank or U-shank blades, not both. Reciprocating saws use the universal 1/2 in shank. Oscillating tools need blades that match the tool's interface (Starlock, OIS or older universal fit). Choose TPI by material: low TPI for wood and demolition, high TPI for thin metal. The wrong shank simply won't lock, and the wrong TPI strips teeth on thin stock or clogs in wood.

What to avoid
- Blades whose RPM rating is below the saw's no-load speed.
- Wood-cutting carbide blades used on ferrous metal (use blades built for steel), or abrasive wheels on saws not designed for them.
- Full-kerf blades on underpowered or cordless saws, and blades thinner than your riving knife.
- High positive-hook blades on sliding miter or radial arm saws.
- Unbranded blades that list no kerf, hook angle, grind or RPM limit.
Questions
Will a T-shank blade fit my jigsaw?
Only if the jigsaw takes T-shank blades, which most current tool-free clamps do. Older or budget saws may accept only U-shank blades. Check the clamp or the manual before buying.
Is a thin-kerf blade worse than a full-kerf one?
No. It wastes less material and is easier on lower-power saws. It can flex more under heavy feed, so full kerf remains the steadier choice on high-power cabinet saws with a matching riving knife.
