For template-follow trimming, ideal for wood, MDF, plywood, and laminates.

Many recommend double-bearing for flexibility with templates on top or bottom and better control.

Spiral designs give smoother cuts and reduce tear-out, especially for template routing.

Use multiple shallow passes and correct cutting direction.

Depends on template location: top-bearing for templates on top, bottom-bearing for templates below.

Correct feed direction, stable support, and a bit with the right diameter.

Bit length and bearing alignment matter; too much difference can affect accuracy.

Use a top-bearing bit for the first pass, then a bottom-bearing bit to finish.

Use protective tape or choose a bearing size that avoids overcutting.

Table-mounted gives more stability; handheld is versatile but requires steady hands.
