Today’s thickness planers vary in price from less than $300 to nearly $500. In an effort to learn whether the price differences reflect the quality and features of the machines, I put nine of them through a hands-on test. To begin with, it’s important that the infeed and outfeed tables be flush with the bed, and I found that all of these machines made it easy to adjust the tables up and down. In addition, I tested how accurately and smoothly the planers cut (all produced amazingly smooth cuts). I also measured the noise level of the machines, checked to see how easy it was to change knives, and gauged the effectiveness of the dust collection.

A long cutterhead-locking lever on the moderately priced Pro-Tech took a lot of effort to engage, and it tied for longest time to change knives. On the other hand, there was minimal snipe and very good carriage parallelism.
