Kreg Owners' Community

I have been using my Kreg Jr. and it is amazing how strong the joints are but I have had trouble with the collar on the drill slipping. Too bad you didn't put a flat on the drill to give some more purchase for the set screw. Do you have any other ideas for me to try?


Thank you.

I just joined the "club", and had to put my 2 cents in on this (problem with slippage). The drill bit supplied with my Kreg Jr. does not allow the setscrew to go into the flute. As far as grinding a flat on the shaft. It only works for twist slippage, unless you also make it rough ( like a file ).
That's a great idea! Thanks, Dave

I have never had a problem with the collar moving. Are you sure you are getting it tight? I tighten the set screw about as tight as I can get it with the supplied allen wrench and I stop pushing on the drill the instant that the stop collar makes contact with the jig. If the set screw is not holding, I cannot see that a flat on the bit would help much as far as preventing the collar from moving along the length of the bit. It could be that I've just been lucky I guess, as I'm fairly certain that I have drilled enough pocket holes for this problem to have surfaced. I have three separate bit/collar combos that I use regularly, so I do not set the depth often, I normally just grab the bit that is already preset for the depth that I want. I'm not suggesting that you get more bits, only that this may be the reason mine holds it's setting (no wear and tear on the set screw).
I have to admit that I love the whole Kreg thing very much and I use these screws everywhere I can. I started using the split collar when using the Kreg bit outside of the pocket hole jig. Sometime later I had to replace a pair of simple bearings that used a set screw to hold the shaft in place. That set screw point displaced enough shaft material to make disassembly a real pain. I decided then and there to continue with the split collar when ever using the Kreg bit.

K5 Review

I really like the k5 it is faster to change from different size of screws. I hesitated to update because of some of the reviews about the dust collection hook up. That to me one of the improvements it works perfect no dust to cleanup .…
