Yes, it is.
I am not so sure. Similar to a 1/2 collet, this size is also available on the market. This size is just meant for a big router that uses a smaller shank.
Selected User Reviews For 1/4" Self Releasing Router Collet Replaces 42999 Porter Cable RC025PC
Described as a replacement for Porter Cable 690 series router bits with a 1/4" shank, this collet is designed to replace the collet in your router. It is impossible to tighten down the collet even when the bits come out. I notice this collet is quite larger compared to my old one. This is a metric size labeled incorrectly, based on my guess. Then it goes back to the beginning.
This is wrong! No matter how tight the collet is, the router bits will still slide in and out. It seems that there is no ring clamp around the collet at the base of the nut as there is with the original OEM item (and all other items of the same design). It could have been included because there is a groove for it. I assumed that the ring clamp had not been installed and the piece was defective. I sent that one back and went out and bought another one. The second piece of the puzzle The rings are not clamped with this version as well. Back to you on this one as well! A different company's photo shows a ring clamp clearly in them, so I have also ordered one from that company. You need to keep your bits in place if you want them to stay Purchase this item at your own risk.
There are some coarse mill marks on the jaws, but that was not what I was expecting. There are very few differences among other products in this price range. Except for that, it performs as I would expect it to.
I like the fit and the functionality of the product.
Exactly what I needed. This really should be all I need to say.
It does what it is supposed to.
Everything went according to plan. No bit I have used has failed to release! I have used it with many different kinds of bits, and not one has failed!.
