The tooth set is the amount the teeth bend sideways from the blade’s body. That small difference affects kerf width, sawdust clearance, heat, and how straight a blade tracks through a resaw cut. Choose too little set for the wood and machine, and the blade may rub or wander. Choose too much, and you remove more wood than necessary and make a rougher cut.
For most workshop resawing, start with the blade maker’s recommendation for your saw, then match the set to the wood, blade width, and desired finish. Tooth set matters, but it cannot compensate for a dull blade, poor tension, or a saw that is out of alignment.

What tooth set does
On a typical raker-set blade, teeth alternate left and right, with a third tooth straight or nearly straight to clear chips. The teeth cut a kerf slightly wider than the blade body. That clearance keeps the blade from binding against the sides of the cut and gives sawdust room to escape.
More set usually means a wider kerf and more clearance. That can help when cutting green, wet, resinous, or thick stock, where sawdust is harder to clear. The trade-off is more material lost, greater cutting effort, and often a rougher surface. Less set leaves a narrower kerf and can improve finish in clean, dry stock, but it gives less room for chips and leaves less margin against rubbing.
Set is not the same as tooth pitch. Pitch is the distance between teeth, often described as teeth per inch (TPI). A coarse blade with fewer teeth generally clears chips better during resawing. A fine-tooth blade may leave a smoother edge, but it can clog and heat up in a deep cut.
Match set to the job
For dry, straight-grained hardwood and ordinary shop resawing, a standard or moderate set is a sensible starting point. It gives enough clearance without wasting as much wood as an aggressive set. Many general-purpose resaw blades are already designed with a set suited to their width and intended cut; avoid trying to alter the set unless you have the right gauge and setting tool.
For green lumber, thick stock, or wood that produces stringy or gummy chips, favor a blade intended for resawing with enough set and a coarse pitch to clear the cut. If the blade begins to slow, squeal, or leave burn marks, do not assume that more set alone will fix it. Check for a dull or damaged tooth, excessive feed pressure, inadequate blade tension, and sawdust packed in the kerf.
For thin resawing where you want to preserve stock, a narrower kerf can save material. The savings are useful when cutting valuable boards or making veneers, but only if the blade still clears the cut reliably. A blade that rubs or wanders can ruin more stock than a slightly wider kerf would have used. On a small, underpowered bandsaw, a less aggressive blade and a slower feed may work better than trying to force a narrow blade through thick hardwood.
Compare common set choices
| Set approach | Best fit | Trade-off to expect |
|---|---|---|
| Standard or moderate set | Dry hardwood, general resawing, most workshop use | Balanced clearance and kerf; not optimized for unusually wet or abrasive stock |
| More aggressive set | Green, gummy, or difficult-to-clear stock | Wider kerf, more waste, and often a rougher cut |
| Reduced or narrow-kerf set | Thin stock, veneer, or jobs where material yield matters | Less clearance; more sensitive to dull teeth, feed pressure, and alignment |
Choose the blade before changing the set
For resawing, blade width and tooth geometry are usually more important than chasing a particular set measurement. Use the widest blade your saw can tension and track correctly, within the manufacturer’s limits. Wider blades resist twisting and tend to stay straighter in a tall cut. A coarse tooth pattern—often around 2 to 3 TPI for substantial resawing—provides gullets large enough to carry sawdust out of the cut. The right pitch depends on stock thickness and blade design, so follow the blade maker’s guidance.
If you are buying for regular resaw work, compare resaw bandsaw blades by width, TPI, tooth form, and intended material—not by set alone. A dedicated resaw blade is usually a better choice than modifying a general-purpose blade. For occasional resawing on a modest saw, an affordable general-purpose blade can be fine, provided it is sharp, correctly sized, and not asked to cut faster than the machine can manage.
Tooth style also matters. Hook teeth have an aggressive rake that can cut quickly in suitable hardwood, but they need a saw and feed rate that can handle them. Skip-tooth designs have larger gullets and can clear chips well, though the cut may be less refined. If you are unsure, a blade sold for resawing in your saw’s supported width is a safer purchase than experimenting with an unusual tooth form.
Read the cut before blaming the set
A blade that drifts consistently to one side may be dull, poorly sharpened, incorrectly tensioned, or tracking badly. Check that the blade guides are close enough to support it without pinching, that the blade tracks as the saw maker specifies, and that the fence is aligned for the blade’s natural drift. Do not compensate for a persistent problem by increasing tooth set; uneven set can make drift worse.
Burning often points to a dull blade, slow chip removal, excessive feed pressure, or a blade rubbing in the kerf. Stop the saw and inspect the teeth for packed resin or damage. If the cut is rough but the blade is not burning, the cause may be tooth pitch, tooth sharpness, or feed technique rather than insufficient set. A slower, steady feed helps, but pushing harder to maintain speed can bend the blade and produce a wavy cut.
Adjustment and maintenance
Set should be even from side to side. Uneven set can make a blade cut crooked, leave one side rougher, and heat the blade unevenly. Measuring individual teeth is difficult without a proper gauge, so most users are better off replacing a worn or badly set blade than attempting a hand adjustment. If you do set teeth yourself, use a tool made for the blade’s pitch and follow its instructions; small errors matter on narrow blades.
Keep blades clean and replace them when they no longer cut freely after cleaning. A sharp blade with moderate set is usually more predictable than a dull blade with extra clearance. Before resawing valuable stock, make a test cut in similar scrap, check the cut for drift and burn marks, and adjust feed rate or setup before committing the board.
