rodger. Posted October 26, 2014 Report Share Posted October 26, 2014 Of my three routers, I have a 2 1/4 HP Dewalt that I use for hand held use. It has three interchangeable bases (plunge, D Handle, standard) and is a great router. I have been using this router for years, and it has been a good tool. I typically use it for any handheld operation, but one of the most typical for me is using it for template routing with a bushing. I was making a few cutting boards, so I made a 1/4" hardboard template for doing the handles a while back. The handles are about 1" deep, and 3" wide. I set up a 1/4" bit and matching bushing in the my router to rout the recess. I take three passes, using the turret stops on the router plunge base. Anyways, I was routing away like I always do. The router started cutting irregularly, and it just didnt feel right. I stopped the motor and waited for it to "wind down". When I lifted the router, the bit fell out! I was flabbergasted. So I went to take the base off, and the motor was so hot it burned my hand. I waited a while for it to cool down, and reinstalled the bit. I did the typical stuff (didnt bottom out the bit, tightened the collet well, etc). I ran the router again and same thing! Only this time the bit was "blued". What the heck happened? Ill take a snap of the bit and add the post in a few minutes. The bit is relatively new,1/2" shank, and from Lee Valley. The material being cut was hardwood, but i wasnt taking deep passes at all. I have perfomed this exact operation many times. Quote Link to comment Share on other sites More sharing options...
Tpt life Posted October 26, 2014 Report Share Posted October 26, 2014 I wonder if you got a bit that is out of balance? Quote Link to comment Share on other sites More sharing options...
rodger. Posted October 26, 2014 Author Report Share Posted October 26, 2014 Here's a pic. The bit was very clean before the operation began. Quote Link to comment Share on other sites More sharing options...

wdwerker Posted October 26, 2014 Report Share Posted October 26, 2014 Collets do wear out and sometimes bits are a little undersized. If you have an accurate pair of calipers compare that bit to the other ones you have. Quote Link to comment Share on other sites More sharing options...
