Blade geometry
A shearing or triple-chip pattern reduces impact at the coating edge.
Machine condition
Fence alignment, arbor runout, and insert clearance can dominate the result.
Jigsaw cutouts
Use a fine reverse-tooth or down-cut blade when the visible face must stay clean, while controlling the tool’s tendency to lift.
Method for this decision
- Mark the presentation face and select a high-tooth or TCG-style blade approved for the saw and coating.
- Check fence alignment, insert clearance, arbor runout, and continuous sheet support before cutting.
- Use a sacrificial backer or approved scoring method, then test the exit edge on a scrap from the same panel.
Worked example
Example: a coated panel can chip even with a fine blade if the insert gap is wide or the fence is misaligned. Correcting machine support may improve the edge more than increasing tooth count again.
Limits and stop conditions
Do not improvise a two-pass or scoring operation that compromises guarding or control. Coating composition varies; follow the panel and blade manufacturer’s dust and cutting guidance.
