Routing metal laminate

[eds1275]

I am going to be using some decometal laminate from Formica soon. Anyone have any experience routing it? I see that there are two expensive metal laminate routing bits available and not a lot on the more budget friendly side of things. I have also read online that some people just go at it no problem with a regular old flush trim - after all, it's only a foil inside. Any advice would be appreciated!

You don't need a special bit in my experience. However I wouldn't be using the cheapest bit you can find either.

I have flush trimmed 3mm aluminum sheet with a "normal" good quality router bit with no issues other than the chips being hot...

Pretty much this as long as it's a good bit.  I would also look to see what speed you should run at.  Higher speeds for wood but lower speeds for metal?

Here's the info for that material, right from the source;

--------

TRIMMING
• Use a small diameter cutter (3/8" (9.53mm)) and a variable speed router set at minimum setting, or use an electronic speed control accessory to reduce router RPM as much as possible.
• Use a flush bit (rather than a bevel bit) that can be adjusted to yield up to 10 fresh cutting edges. Protect the self-edge face with masking tape at the bearing line.
• Feed the router as fast as possible. Rough cut at one height adjustment and re-trim at a fresh cutting edge. Retract cutter from the work piece as soon as cut is complete. Dwelling in one spot during start or finish will greatly diminish cutter life. Plan your cutting strategy to reduce static start and stops.
• Having excessive overhang will allow for excessive heat buildup, which could cause delamination of the aluminum surface from the phenolic core.
• Finish the edges with a fine file, always cutting on the downward stroke.
