How to Avoid Tearout When Cutting Plywood
Stop plywood tearout and splintering: blade choice, scoring, tape, zero-clearance support, and feed-rate tips for clean edges on every cut.

How can a personal builder use CutList to finish how to avoid tearout when cutting plywood with fewer mistakes?
The hobby workflow is strongest when the app is used as a planning checkpoint: define the project, enter accurate stock and parts, generate a visual layout, then use cost, waste, grain, kerf, PDF export, project history, and offline access to control the real cutting session.

Why Plywood Tears Out
Tearout happens when the blade lifts and splinters the thin face veneer instead of slicing it cleanly. It is worst where teeth exit the surface: the bottom face on a table saw, the top face on a circular saw or track saw. Thin veneers, dull blades, and fast feed rates all make it worse. The fixes all aim to support the veneer fibers so they cannot lift.
Use a Fine-Tooth Blade
A blade with more teeth (60-80 on a 10-inch saw, or a dedicated plywood/laminate blade) takes smaller bites and leaves a cleaner edge. A general-purpose ripping blade with few teeth is fast but tears veneer. A sharp fine-tooth blade is the single biggest improvement for clean plywood cuts.
Score the Cut Line
Scoring the veneer before the full cut severs the surface fibers so they cannot splinter. On a track saw, a light scoring pass along the rail does this. By hand, a knife scored along a straightedge on the cut line works. The main cut then follows the pre-cut line cleanly.
Support the Exit Face
A zero-clearance insert or a sacrificial backer board supports the veneer right where the blade exits. With no gap under the cut, the fibers have nothing to splinter into. Painter's tape over the cut line adds light support and is a quick help on a circular saw.
Mind Blade Direction and Feed
Put the good face where teeth enter: up on a table saw, down on a circular or track saw. Feed steadily without forcing, and let a sharp blade do the work. Rushing a cut or backing up mid-cut both invite tearout. Slow, supported, sharp: that is the whole formula.

Field Checklist
- Use a sharp fine-tooth or plywood blade.
- Score the veneer before the main cut.
- Support the exit face with zero-clearance or a backer.
- Put the good face where teeth enter the wood.
- Feed steadily and never force the cut.
FAQ
Common questions
Why does plywood splinter when I cut it?
The blade lifts and tears the thin face veneer as teeth exit the surface, especially with dull or coarse blades and fast feed rates.
What blade is best for cutting plywood without tearout?
A sharp fine-tooth blade (60-80 teeth) or a dedicated plywood/laminate blade takes small bites and leaves a clean edge.
Does painter's tape really reduce tearout?
Yes, lightly. Tape over the cut line supports surface fibers and helps most on circular-saw cuts.
Which side tears out, top or bottom?
Teeth tear the exit face: the bottom on a table saw, the top on a circular or track saw. Put the good face where teeth enter.
What is a zero-clearance insert?
A throat plate with no gap around the blade, so it supports the veneer right at the cut and prevents splintering underneath.
