The best jigsaw blade for plywood is usually a fine-tooth, narrow-to-medium blade matched to the sheet thickness: use about 10–12 TPI for 12–19 mm plywood, 14–20 TPI for thin panels, and either a reverse-tooth blade or finished-face-down setup to protect the visible surface.

Quick picks by plywood thickness and cut quality
| Plywood and cut | Recommended blade | Typical tooth count | Blade width | Orbital action |
|---|---|---|---|---|
| 3–6 mm, straight cuts | Fine-tooth wood blade | 14–20 TPI | 6–10 mm | Off or low |
| 9–12 mm, clean visible edge | Fine-tooth or reverse-tooth blade | 10–14 TPI | 8–12 mm | Off or low |
| 15–19 mm, general-purpose cutting | Progressive-pitch wood blade | 8–12 TPI | 10–13 mm | Low to medium |
| 18–25 mm, fast rough cuts | Coarser wood-cutting blade | 6–10 TPI | 10–13 mm | Medium |
| Veneered, melamine-faced, or painted plywood | Reverse-tooth or laminate blade | 10–20 TPI | 6–10 mm | Off |
These figures are starting points rather than rigid rules. A plywood jigsaw blade with too few teeth can chip the face and catch in thin stock; one with too many teeth can cut slowly, heat up, and clog with dust or resin.
How tooth direction controls tear-out
Most jigsaws cut on the upstroke. A conventional blade therefore tends to pull fibers upward as it exits the top face, leaving the most visible splintering on that side. If the better face is the top surface, place the plywood face down and cut from the back with a conventional blade. The jigsaw’s base plate then travels over the less important face while the cleanest edge remains on the visible side.
A reverse-tooth blade cuts on the downstroke. It is useful when the finished face must remain upward, such as when the plywood is already fixed in place or the underside cannot be accessed. Reverse-tooth blades require a steady feed because their cutting action can make the tool feel as if it is being pushed upward. Keep firm downward pressure on the shoe, but do not force the blade.
On some reverse-tooth blades, the lower teeth extend below the shoe during the stroke. Check clearance before cutting, especially on a workbench, and follow the blade manufacturer’s instructions for orbital settings. Orbital action generally increases speed by moving the blade forward on part of its stroke, but it also increases chipping. Use no orbital action for the cleanest face.
Choose blade width for the shape, not just the material
Blade width affects control. A 10–13 mm blade tracks more accurately along a straight guide and resists twisting in 18 mm plywood. A 6–8 mm blade turns more easily for circles, cutouts, and tight curves, but it is easier to deflect. Narrow scrolling blades are appropriate for small-radius curves, not for forcing a long straight cut.
- Straight cuts: choose a wider blade, support the sheet, and use a straightedge when accuracy matters.
- Large curves: use a medium-width blade with roughly 10–14 TPI.
- Tight curves: use a narrow scrolling blade, make relief cuts, and accept a slower feed rate.
- Thick plywood: ensure the blade’s toothed length exceeds the material thickness by at least 6 mm so the gullets can clear waste.
For example, a 19 mm panel needs a blade with substantially more than 19 mm of usable toothed length. A short blade may technically pass through the sheet but leave the gullets buried, causing heat, vibration, and a rough edge.
Decision matrix: which jigsaw blade should you buy?
| Your situation | Best choice | Why | Trade-off |
|---|---|---|---|
| Occasional DIY cuts in 12–18 mm plywood | 10–12 TPI medium-width wood blade | Good balance of speed, control, and availability | May need masking tape for a show face |
| Cabinet parts or visible veneer | 10–14 TPI clean-cut or reverse-tooth blade | Reduces breakout at the finished face | Slower cutting and more heat |
| Thin 3–6 mm panels | 14–20 TPI fine-tooth blade | More teeth remain engaged, preventing snagging | Clogs more readily in resinous plywood |
| Many long cuts each week | Progressive-pitch blade plus a small fine-tooth pack | Progressive teeth clear waste while the fine section improves the entry and exit | Consumable cost is higher than using one coarse blade |
| Frequent curves or interior cutouts | 6–8 mm narrow scrolling blade | Turns without excessive twisting | Less suitable for fast, straight ripping |
How to get a cleaner plywood cut
1. Select the correct shank and blade length
Confirm whether your jigsaw accepts T-shank or U-shank blades; many current jigsaws use T-shank blades, but compatibility is not universal. Select a blade long enough to clear the sheet throughout the stroke. A blade that bottoms out against the work surface can damage teeth and create kickback-like movement.
2. Support the sheet close to the cut
Place the plywood on sacrificial foam or evenly spaced supports so the offcut cannot sag and tear away at the exit. Clamp the work securely, but leave room for the jigsaw shoe and cord or battery pack. Unsupported sheet material vibrates, which causes more splintering than a modest difference in tooth count.
3. Protect the finished face
For a conventional blade, mark the line on the back and put the finished face down. For a finished-face-up cut, apply low-tack masking tape over the cut line, score the line with a sharp knife, or use a reverse-tooth blade. Tape is a helpful supplement, not a substitute for a suitable blade: aggressive orbital action can still chip the bottom veneer.
4. Set speed and orbital action
Begin with orbital action off and a moderate speed. Increase speed only if the blade is cutting cleanly without heat discoloration or burning. Hard hardwood plywood and laminated surfaces usually benefit from a slower, controlled setting. Let the teeth cut; pushing harder bends the blade and makes the cut wander.
5. Enter and exit carefully
Start with the shoe flat on the workpiece and allow the blade to reach operating speed before moving forward. Near the end of the cut, support the offcut and reduce pressure. A plunge exit or unsupported final inch is a common cause of veneer tear-out. For an enclosed cutout, drill a starter hole larger than the blade’s width, then turn into the marked line gradually.
Blade materials and ownership costs
High-carbon steel blades are economical and suitable for ordinary softwood plywood, but their teeth dull faster in hardwood veneers, glue-heavy panels, and abrasive laminates. Bi-metal blades combine a flexible body with harder teeth and usually tolerate more bending and heat. Carbide-grit blades are useful for abrasive cement-bonded, laminate-faced, or specialty panels, but they are not normally the best value for clean ordinary plywood cuts because they remove material differently and may leave a less furniture-like edge.
As a general market range in 2026, basic wood blade packs commonly cost about $8–$20, bi-metal or specialized clean-cut packs about $15–$35, and carbide-grit options about $15–$40. If a blade pack costs $20 and contains five blades, the consumable cost is $4 per blade. If one blade produces 15 clean cabinet cuts before dulling, that is roughly $0.27 per cut; using a dull blade to save money can cost more in sanding, damaged veneer, and rework.
The teeth usually wear first, especially near the tip. Replace a blade when it needs force, burns the edge, wanders despite proper support, or leaves repeated chips in otherwise stable plywood. Brush dust from the jigsaw shoe and vents after cutting, keep blades dry, and store them where teeth cannot rub against metal tools.
Common mistakes to avoid
- Using a coarse, six-tooth blade on thin plywood and expecting a clean veneer edge.
- Running maximum orbital action on a visible face.
- Forcing a narrow blade through a straight cut instead of using a wider blade or guide.
- Cutting with a blade whose teeth are shorter than the plywood is thick.
- Allowing the offcut to fall before the final teeth leave the panel.
- Assuming masking tape can compensate for a dull or incorrectly oriented blade.
For most workshop projects, start with a 10–12 TPI medium-width blade for 12–19 mm plywood, add a 14–20 TPI blade for thin stock, and keep a reverse-tooth option for finished-face-up work. That small selection covers the main plywood cutting situations while giving you control over speed, curves, and splintering.
