How do I know if my blade is dull?

Signs of a dull blade include burning or scorch marks on the wood, more tearout than usual, the saw bogging down or needing more feed pressure, and a rougher cut. A quality carbide blade can be resharpened several times before replacement.

Can I put a table saw blade on my miter saw?

Yes, as long as the diameter, arbor and max RPM match. Many 10 in blades are labeled for both. Just note that a high positive hook angle meant for table-saw ripping can grab on a miter saw, so a lower-hook crosscut blade is safer there.

Why does my blade leave burn marks?

Burning usually means the blade is dull, dirty with pitch, has too many teeth for the material, or you are feeding too slowly. Clean the blade, check for sharpness, and use the right tooth count: too many teeth on a rip cut generates heat instead of clearing chips.

How to Choose a Table or Miter Saw Blade

By The DIYPicks Team · Updated July 2026

The blade matters more than the saw for cut quality. Choosing well comes down to four things: tooth count, tooth grind, kerf and fit. This guide explains how each affects your cut so you can match the blade to the job instead of guessing at the store.

Tooth count by cut type

Tooth count is the single biggest driver of cut quality and speed. Fewer teeth cut faster and clear chips better, which is what you want for ripping along the grain. More teeth cut slower but leave a cleaner edge, which is what crosscutting across the grain needs.

As a rough guide on a 10 in blade: 24 teeth for fast ripping, 40 teeth for general-purpose combination work, 60 teeth for good crosscuts, and 80 teeth for fine finish crosscuts on trim and veneered plywood. If you only buy one blade, a 40-tooth combination covers the most ground.

Tooth grind: ATB, FTG and Hi-ATB

The grind is the shape of the tooth tips. ATB (alternate top bevel) teeth alternate their bevel left and right, slicing wood fibers for a clean crosscut; this is the most common grind. FTG (flat top grind) teeth are flat and chisel through material, best for fast ripping but leaving a rougher edge.

Combination blades use a mix (often 4 ATB teeth followed by 1 FTG raker) to balance ripping and crosscutting. Fine-finish blades use Hi-ATB, a steeper bevel that gives the cleanest edge on melamine and veneer but dulls faster. Match the grind to whether you rip, crosscut or do both.

Kerf: thin vs full

Kerf is how wide a slot the blade cuts. A full kerf (around 0.098 in) blade is thicker and more rigid, tracking straighter and resisting deflection on powerful cabinet saws with 3 or more horsepower.

A thin kerf (around 0.070 in) blade removes less material and requires less power, so it cuts better on underpowered contractor and jobsite saws and wastes less expensive hardwood. If your saw bogs down in thick stock, switch to thin kerf.

Fit: diameter, arbor and max RPM

Diameter and arbor must match your saw exactly. Most 10 in table and miter saws use a 10 in blade with a 5/8 in arbor; smaller trim saws use 7-1/4 in or 8-1/2 in blades. Never force a blade with the wrong arbor onto the shaft.

Every blade has a maximum safe RPM printed on the plate. Confirm it is at or above your saw's speed. Running a blade faster than its rating risks it coming apart, which is one of the most dangerous failures on a saw.

Hook angle and safety

Hook angle is how far the teeth lean forward. A high positive hook (around 15 to 20 degrees) pulls material into the blade for aggressive ripping on a table saw. A low or negative hook slows the feed and improves control, which is why miter and sliding saws favor lower hook angles to prevent the blade from grabbing and climbing the stock.

Whatever blade you choose, unplug the saw before changing it, use a zero-clearance insert to reduce tearout and support small offcuts, and keep the blade clean; pitch buildup causes burning and overworks the motor.
