Woodworking Experience:
I highly recommend the Porter Cable Dovetail jig for both beginners and experienced wood workers.
I wanted to make a retirement gift for my boss and it was going to be a box with plexi-glass windows for him to display something in. I wanted it to really stand out and there is no better way for a box to stand out than for it to have through dovetail corners. I did a bunch of research and decided to buy the Porter Cable Dovetail Jig, and boy am I glad I did. This was the first time I have ever made dovetails and I think they came out great. I did have to practice a few times on some scrap pieces, but within a couple hours of taking it out of the packaging, I had a nice tight 18" x 10" wooden box that didn't even need wood glue to hold it together. Just make sure you follow the directions on the side of the jig AND the manual.
The back of the box. Grid coordinates to a secrete location??
The Dovetails are so tight, there is no glue holding the box together.

4212 porter cable dovetail jig
Made much more solidly than competitor's copied products, and the engineering put into it makes it much easier to have success when making dovetails.
The instruction manual is a bit challenging and takes some serious study however.
Overall, feel it is worth the higher price over similar products.

Some good thought went into this design!
I purchased this jig to replace a much older PC dovetail jig. The trouble with the older jig was the weak hardware--I stripped out a few of the hold-down screws--and the small size was difficult to cinch down. This resulted in the stock wandering off, giving me an extremely inaccurate dovetail alignment. Now--with this new jig--those issues are solved! I have only cut the half-blind dovetails, but the first time result was impressive.

Porter Cable Dovetail Jig
Pluses: Solid clamps, a mostly useful owners manual, an actual response from customer service.

Cons: The recommended router bit height setting in the manual is way off. Far enough that it was not obvious what was wrong. Big issue? Not really. If I was a better wood worker this would have been no problem at all.

Does this jig cut pins and tails at the same time?
Bill L on May 12, 2016
BEST ANSWER: Yes; 1 work piece is clamped in vertically, the second is on top horizontally, make sure the vertical is offset the width of the pin: takes a little practice you would want to play around with some scrap till you get the hang of it. Not to mention setting the depth of the router bit will require some practice as well, to get a clean joint
Need Miniature jig for 4212?
A shopper on May 31, 2015
BEST ANSWER: The answer that's titled 'Best Answer' is confusingly worded. The PC 4212 jig works with all 17/32 and 13/32 dovetail router bits. Freud is one of the other manufacturers that makes bits compatible with the 4212. However, the miniature jig only works with a 9/32 dovetail bit. Other manufacturers make these bits too, but the bits from all the manufacturers are steel, not carbide tipped.
does this jig come with router bits included or do we need to purchase the compatible bits now?
rick l on Dec 30, 2015

It does come with 4 bits; two for small dovetails (43777PC), two for the larger ones (43776PC).

The large bits are carbide tipped, but the small bits are high-speed steel, and from my experience, burn quite easily. Finding replacement bits made by anyone other than Porter Cable was an exercise in frustration, as was trying to find solid carbide version of the 43777PC. Many websites "claim" to sell this bit as carbide, only to find out they're selling the high-speed steel version.

Rocker does not sell a router bit that works with the PC jig.

Hope this helps-

Is the PC jig compatable with a dewalt router?
Richard B on Dec 15, 2015
BEST ANSWER: As long as you can fit a template bushing in the base it will work with any router.
What size router bit and guide bushing are used with a template w/ 1/2" fingers?
MikeL on May 31, 2017
BEST ANSWER: For the model 4213 miniature dovetail jig, you will need the Porter Cable 9/32'. 7 degree dovetail bit (43777PC) with a 3/8" template guide or the 5/16" template guide and 3/16" straight bit for finger joints.
Has anyone found a dust control jig for the 4212? It just makes clouds of dust all over everything. I've hunted but never found one.
Daniel on Oct 28, 2016
BEST ANSWER: Attach a lathe or miter saw dust shroud to the back of the table you made for the dovetail jig or use a dust port for your router. I think rockler has a mobile dust port clamp.
Is there a way to dovetail stock that is wider than 12"?
Evan S on Feb 9, 2020
BEST ANSWER: I'm not at the shop to measure the capacity of the jig, but it is a fixed width, close to 12". I've done dozens of drawers with it, and it works great but is limited in width.
The other models say they come with instructions, I assume this does too?
John on Jan 3, 2019
BEST ANSWER: Yes, for me it's a bit technical so I also relied on youtube videos.
What is the best router bit when using plywood?
StevieE on Jan 19, 2019
BEST ANSWER: Plywood wears out bits quickly. Use carbide. Toss it when it wears out. Some hone their carbide bits on a diamond stone lightly. You don’t want something that spins at 20000 rpm to be unbalanced.
I have a 4212 jig and made the mistake of adjusting the router bit depth gauge. For through dovetails, should the depth gauge be 3/8", no more and no less?
Don V on Jan 15, 2019
BEST ANSWER: I think so, but for best advice, I'd recommend writing/emailing Porter and see if their tech folks can answer this definitively.
It requires a half inch collet right? I have a three horse router that would be too heavy to use for this. Do they make one with a quarter inch collet?
John P on May 19, 2019
BEST ANSWER: You and I have invested in an excellent dovetail jig. Safety and damage control is my first priority. I refuse to use my heavyweight router on my 12 inch jig, instead I prefer using my medium size router under two horsepower. Several good brands out there to choice from, I elected to use Bosch since I have three on hand. However Porter cable is a good choice and affordable.
Can you use a mini 1/4” router with the 4212 jig?
Gerald F on Dec 7, 2018
BEST ANSWER: I am not sure, I never tried to. But if you have the right atachements it should work
Bits for box joints did not come with the jig (I received 2 sets of bits for dovetails only). Which bits should I buy for box joints? For normal template and the miniature one? Thank you.
adamduman on Apr 9, 2018
BEST ANSWER: The manual states that you need a 1/2” straight bit.
I have a the pc dovetail jig 4212 that comes with the 43776pc, 1/2 inch shank. what bit is equivalent for a router that uses 1/8 shank? Needed for have blind dovetails.
Ed A on Jan 22, 2018
BEST ANSWER: I personally would not use an 1/8" bit for making dovetails. When removing that much wood, I think it would put excessive stain on the bit. Causing it to either flex or worse, shatter.
