Using the 491026 Chamfer/Edge Trim Bit

[snachlas]

I just bought this bit to use with my MFK 700 trim router.  I just wanted to get some ideas on how some of you set this bit's height in the router.  It appears that it is meant to both flush trim the laminate and cut a bevel at the same time.
I would appreciate any tips some of you gave as to height settings.

Also, mine came (from Amazon) with a black plastic bearing.  All of the pictures that I have seen show the bit with a steel bearing.  Is the plastic perhaps a newer design?  It is certainly less costly to produce.

Thanks

The bit set up will depend on the laminate. If it is color through you can cut a "larger" bevel. If it has a dark mica core you'll have to decide how much of the dark core you want to see.

Test cuts are your friend.

Set the bit to flush cut only, gradually raise the base until you get the look you want.

Thanks Tom.  That's pretty much what I figured. Most of woodworking works best when we "creep up" on our results!

If it black its most likely Teflon coated and is used so the adhesive in the laminate you are cutting does not gum up the bearing. The metal bearings gum up super fast so if it a good bit its a step up, but I have had some teflon bearings that really dind't seem to do any better.

The black Teflon bearings come in two types, one the more common traditional round bearing that spins, the other type is  square and just rubs up on the side and doesn't spin.

Thanks very much.  I have seen the square bits.  This one is round.  On closer inspection, I noticed that the bearing is actually steel with what looks like about a 2 mm Delrin or other type of plastic as the outer surface.  This should help to protect the work surface as will as be less likely to gum up.

Spray the edge with furniture polish before you run the bit along it.

Like Tom I use a protectant.  I have always used paste wax.

I spray my bits with WD-40.
