Default MY PC 7518 collet was junk, I replaced it with a Precision Collet what a difference.

I posted this in another forum but I thought it was worth posting here.

I don't know maybe I just got a bad one but the collet on my PC 7518 is just junk. I have to wrap a rag around the bit to install it and then to take it out so I won't cut myself. Even off the router it is hard to get a bit in without wrapping it with a rag.

I did some searching on the net and found PreciseBits, not affiliated with them in any way.

The collet they sell is not that high when you see the collet, $70 and you get a 1/4" and 1/2" collet, the nut the wrench and a small bottle of ColletCare (super light oil). You can also just get a 1/2" collet kit with wrench and the ColletCare for $55.

The PC collet has 4 parts around it to clamp on the bit and the PreciseBits has 8, now right off the bat you can see it is better. The nut uses a spanner wrench which I was not really sure of but after I got it and used it I love it, you slip it on, loosen the collet and it will just stay on the nut if you want it to so you are ready to tighten up the next bit.

I used my Woodpecker Saw Gauge with a digital dial indicator on it to check the run out on both the PC and the PreciseBits collets. I first used the ColletCare to clean both the PC and the PreciseBits collets, the inside of the router shaft and the 1/2" straight bit. The PC had a run out of .003 and the PreciseBits had a run out of .000. One time while checking the PreciseBits I saw the indicator go to .0005 and then cleaned the bit off again and it stayed at .000. I made the check 3 different times and came up with the same on each test.

Installing a bit is a dream, it is smooth and easy, no pushing it just slides it in but it will stop at any point when you let go of the bit. Removing the bit is just as nice, loosen the nut and just lift the bit out.

I will have to say they really have an awesome collet, if you have a PC router I would sure take a look at them.
They sell a collet that is compatible with
Porter-Cable families - 2902, 6302, 690, 690LR, 9690LR, 691, 693, 890, 891, 892, 893, 7518, 7519, 7536, 7537, 7538, 7539, 883799X routers
