Often, if I have an issue or question, I just hit the search box and it’s good. This one has me a bit stumped (and a bit worried).You need a new collet. Even without actual damage, collets do not last forever. They are made of spring steel and over many cycles of heating and cooling as they get used, the temper of the spring steel is lost. This causes it to not grip properly. I use my router a lot, so I replace my collets about every two years. Your milage may vary, but once the collet won’t hold, it needs replacement.

What they suggested made sense. Put a little oil or graphite on the angle surfaces inside the shaft and on the outside of the collet. Be sure that the inside cylindrical part of the collet is clean and dry (where the bit shank goes). this has worked for me when I've had slippage problems with collets. RE: Wandering router bits - castguy2003 - 07-15-2021 Ditto on a new collet and here is a trick we used in the machining trade. Get yourself a bottle or spray can of blue or red Dykem layout fluid and paint your router bit shaft with it. Let it dry then install as usual. The layout dye adds a lot of "bite" to the collet and should eliminate your problem. RE: Wandering router bits - NickNC - 07-15-2021 Thanks all, knew I’d get some pretty good answers here. New collet ordered. Castguy – I never thought of the Dykem, but I did get in the habit of using Penetrol on a lot of my metal stuff. Garage is unconditioned and humidity can get pretty high here. I’ll try it. RE: Wandering router bits - handi - 07-18-2021 (07-15-2021, 10:05 AM)NickNC Wrote: Thanks all, knew I’d get some pretty good answers here. New collet ordered.

Paste wax is your friend. Wax will protect the collet, nut and bit from rust. It will also lightly lubricate the mating metal surfaces. Counter-intuitively, this makes collets hold bits better since the mating surfaces do not bind through friction before being actually tight. Many makers of CNC collets and tool holders are now coating their products to minimize the unwanted friction. Paste wax will give you the same effect in your home shop. RE: Wandering router bits - brianwelch - 07-23-2021 I have had the same issue but turned out not to be the collet, but as mentioned above, the height adjustment lock... 1/2" bits are a great improvement, but will have little effect if it is the same problem I had...

This is most definitely the collet Brian. I now stop every few passes to tighten it. Hopefully new one arrives today. I don’t have through-table adjustment. On mine (three base style) you have to physically release a compression lever then dial the body up or down with an adjusting ring and clamp it back down again. You’re the second person now to report that issue – maybe I won’t upgrade. |
