Porter Cable 4212 Report

The manual suggests that any bit somewhat over 1/2" will work. They specifically mention 9/16" and 5/8".

As you suggest, maybe someone included a 1/2" bit.

I wish my calipers worked well enough to see that but cheap chinese don't measure very well.

Yep.. I agree that a wrong bit might have been shipped and it caused me a LOT of grief. I don't know why I didn't get another bit earlier.

I haven't tried the "alternate" bit setups yet.

They have all sorts of weird combo's on the "advanced manual".

ALL TOGETHER NOW!

Sorry I could not resist. ;~) But you are right, if you knew the old stuff you are becoming more disappointed in the new stuff even if it is the old style new stuff.

I had the same experience, same dovetail jig. Same Freud replacement bit.

I knew I wasn't the only one....

Thanks for speak I had the same experience, same dovetail jig.

I got to thinking, have you tried using a slightly smaller diameter guide bushing? That will let the bit cut a wider path.

No.. I wanted it to work as "advertised" before I started screwing around with "other" setting.

The Freud bit fixed the problem instantly.

If I get a chance this weekend, I plan on taking a picture or two of the two bits in action and the results.

The geometry of these jigs are a mystery to me. I don't understand why "any" dovetail bit wouldn't work with this jig.

The over all length of the bit certainly has a bearing on what works and what doesn't.

The template are "set" to 1/2" so, I'm not sure what happens if you use a smaller template guide.
