I’ve had this problem for a while. When I set the depth, particularly when it’s a deep cut, the lock doesn’t hold it in position and eventually creeps up. Anyone have this issue or know how to solve it?

First thing is to figure whether it is the bit creeping in the collet, or the router moving in the base.
You could try tightening / adjusting the clamp on the router base.

Also multiple light passes would be better than one deep cut.

I run a 1617 and have never experienced your problem. I agree with Kevin’s thought: confirm that you’re chucked properly and tightly. You’re experiencing this with both sizes of collet? For your sake I hope not because the fix is likely more than learning to work around the one troublesome collet.

I also use Bosch’s Colt and it is the only router that I’ve ever used where bit-creep is the norm. Pisses me right off, but the 1617 is a solid performer.

It is the plunge base. The latch doesn’t hold the guide rails where I set them. When I hold the latch and push down to the desired depth, then release to lock it in place. It creeps up. I tried tightening the screw but it doesn’t help.

You might try wiping the parts that push together to lock with denatured alcohol. Some of the moving parts are lubed and some lubricant or dust may have gotten into the locking mechanism.

I use aerosol teflon cutting lubes on some of my bits, and the overspray sometimes causes the problem with my plunge bases, not limited to the Bosch.

Have your say...
