I am building a deck.To the point, I needed to trim an area of decking flush and couldn't use a circular saw in this area in so I thought a router would do it and purchased a CMT 1 1/2 inch flush trim bit. I trimmed the area fairly close with a jigsaw and then used the router. In about 10 seconds the bearing came flying off and the the bit dug in where it shouldn't have and I said a few bad words.
Yes! I did check to see that the set screw was snug before I used it. I was able to find the bearing and robbed a set screw from another bit only to find that the errant bit's set screw hole was stripped. Now, you know how expensive good router bits are, so this caused me to say another bad word.
Soooo, was it something I did? I would like to NOT do it again. Or, was it the bit's fault?
Thanks for your help.
If you did something wrong, it was minor like not checking to see if the bearing turned freely when you installed the bit...or if it was lubed properly. But bottom line is that CMT owes you one. It shouldnt have happened. Send bit back to Dave McCormack at CMT 307-F Pomona Drive, Greensboro, NC 27407 and include a copy of this note.
