You set the bit depth so that the bearing rides on the substrate below the laminate to be trimmed. You may need to go a little deeper if that edge is poor because you hold the bearing against the substrate while the spinning cutters engage and remove the excess laminate.
You place the base on the laminate surface then slide it into the cut and push it along plowing away the excess laminate. The bearing follows the substrate thus trimming it off even. I usually choose to finish the cut with a touch of a file particularly where the top is overhanging edge trim. Some of these bits have a very slight bevel in which case you need to adjust the depth of the bit more carefully. These bits are used on single speed routers all of the time so high speed is no challenge, full thirty thousand RPM if you like. If there is a lot of adhesive you may wish to slow it down a little because the heat will reactivate the contact cement and it can get into the bearing stopping it from spinning when it cools. I suppose a dip in oil might reduce that I don't know. Hope this helps. ----- Original Message ----- From: Scott Howell To: [email protected] Sent: Tuesday, August 25, 2009 5:29 AM Subject: [BlindHandyMan] Using a laminate router bit Folks, I have a question. I got a laminate router bit to trim some thin laminate material, which will go on the unfinished end of a counter top. Now I tried using a utility knife and all that, but this is a case where the router might work a little better. Since the bit was pretty inexpensive, I'm more interested in just trying this out since I could with a lot of patience work at cutting and smoothing. In any case, there is a baring at the bottom of the bit and then the cutting edge. How does one effectively use this bit and at what speed would I want to trim the material? tnx, [Non-text portions of this message have been removed]
