I need a LONG 3/8 straight router bit


The SOSS hinges and template that I just purchased call for a router bit that is 3/8 in cutting diameter and 3 3/4 inches long. The longest I can find is 3 inches. I'm sure I could probably not set it as deep but I don't know how safe that would be. I tried calling SOSS today but they are closed until Monday. Anybody here know who makes an extra long router bit?

Take a look at the hinge you have and track its movement. I have a pair of a smaller SOSS hidden hinge and seem to recall that you could likely get by simply by drilling out the majority of the mortise using a 3/8" drill, clean up a bit with a chisel and then do the final routing of the mortise with the router.
Again, I'm certain that this would work with the smaller SOSS hinge that I have and one would never know the difference until you removed the hinge and examined the mortise.
I'd certainly try it this way before I seated that 3" router bit at the very tip and crossed my fingers. That sounds like one of those deals where you later hear the victim say.. "You know, I had this feeling that..." or, alternatively is preceded with the phrase, "Hey! Watch this!"<g>

I thought about the 3/8" drill but I'm too afraid of screwing up the doors. And, I just bought this fancy jig that's supposed to make everything come out perfect so I want to use it! :-)
Don't worry, there's no way I was going to use a 3" bit inserted "just enough" to hold it in at 20,000 rpm.... How much would that be anyways? :-)
Doctor to me "Tell me again how this router bit became lodged in your groin." Me "Well, it all started with some SOSS hinges for an entertainment center I'm building...."

Visit www.kbctools.com and look up their part number 1-3242-017 - it's a 3/8" x 4"OAL with a 2" flute length carbide end mill that they list for $25.88
Two lines below that is a 3/8" x 6"OAL with a 3" flute length for $37.67
I've used mills from this Niagra Cutter series in a CNC router with good results - and KBC has been a good supplier.

How much do you have to slow that down? I'd be a bit worried about flex in a 4" - 3/8 bit.

I wouldn't slow it down at all - but then, I wouldn't use it in other than a CNC environment either. It's worth remembering that these end mills are designed and fabricated to cut metals using a nice solid milling machine. They do a first class job of routing wood and (at least some) plastics as well.
My sense is that the feed (how fast the bit moves through the workpiece) and speed (how fast the bit is rotated) that works best in a given material for a "short" bit is the same as that for a "long" bit; and that every material has a feed/speed "sweet spot" where smoothness of cut, chip size, etc all seem to come out right. My CNC router is so quiet that I can tell just by listening when feed and speed are right for the material. I strongly suspect that it's much the same in metalworking (CW?)
Even a 4" x 3/8" carbide bit shouldn't flex much (at least not much in woodworking terms). My concern would be for smooth, even feed because small (tilt type) irregularities in router motion will produce larger irregularities at the end of a 4" or 6" shaft.

Morris,
Thank you! I don't know how many "Googles" I have done but alas I was looking for router bits and never thought about CNC tools. This is exactly what I need. Any idea if they carry a sleeve so this will fit in my 1/2 inch router chuck? MLCS carrys them but it's only a 4 dollar item and I'll pay more than that for shipping.
Thanks again.
Bryan

De nada. Instead of a sleeve, please [PLEASE!] spend for the 3/8" collet from your router manufacturer. I think it'll be a much safer solution (50% fewer possibilities for slippage) - and may well pay for itself in the first project.

I just want to follow up on my previous post:
I found that the Porter-Cable 42975 3/8" collet costs $11.95 - and the PC 42133 3/8" to 1/2" collet adapter (sleeve) costs $11.69 (both at Amazon).
For the 26-cent difference, I'd go for the PC 42975 collet. BTW, this is advertized as fitting the PC 690, 9690, 691, 693, 693PK, 7529, 97529, 7518, 7519, 7538, and 7539 routers.
I'm guessing that the other vendors/manufacturers are offering similar non-savings.

Any idea if this collet will fit my Freud 2000 router? Freud doesn't make a 3/8 collet (at least not that I can find).
Thanks

Highly doubtful. Every manufacturer seems to have their own design.
