Taking it to a new level
Haven't had them long enough to test durability but set right to task with one and all good results in multiple mortising.

Surprisingly good
I use these in a Jet JFM5 (nice mortiser btw). I also have a Forrest City set which costs about 5 times as much. If you set the jet chisels and bits up right and use proper technique, you get results just as good as the Forrest City units. The Jet chisels aren't as beefy and the bit shanks are short (requiring the shank extension in the JFM5), but considering you can buy five for the price of one FCT set, who cares?

Good chisel set at a good price
This is a good set of chisels at a good price. They cut very clean, and eject the chips well.

More bang for the buck
I use this product in an educational setting The students use it to make mortise and tenon joints on their projects. Some of them being, Chair joints, table joints, bed joints. The parts are easy to work with and set up and cut precise joints. I would recommend this product to the professional woodworker as well as a novice.

How much longer are the bits vs. the chisels? I'm trying to gage if these will work on my mortiser, the 1.75" of a "standard" economy set are not long enough to reach the chuck.
