How to Avoid Tear-Out When Routing with Templates

Short answer: template-routing tear-out comes from lifting the surface fibres faster than the bit shears them. Use a compression or downcut spiral for the final pass, keep the template firmly supported, and take a light finishing cut with a sharp edge.

Why the top face chips

When a router bit follows a template, the outer veneer of plywood or melamine is unsupported at the moment of exit. An upcut spiral pulls fibres upward, so brittle face veneers break instead of shearing. A compression spiral presses the top fibres down and the bottom fibres up, keeping both faces clean.

Three practical checks before the final pass

First, confirm the template is clamped flat and the bearing or guide bushing runs smoothly — chatter shows up as chipped edges. Second, leave a thin skin of material and remove it in one light finishing pass. Third, rotate reversible insert knives to a fresh edge before the finishing pass; dull edges crush fibres rather than cutting them.
