Powermatic® 20'' Planer 5HP 1PH

Item #
74% of 100

This heavy duty planer offers performance and value, loaded with standard features not found on other machines in its class. The powerful 5HP motor and 20" planing capacity will handle the most demanding work. The helical cutterhead provides quieter operation and finer finishing than conventional systems, and the four-sided knife inserts seat themselves without requiring a set-up gauge. The 5" dust port connects easily to any dust collector. The anti-kickback fingers and pressure bar are located in close proximity to the cutterhead for an exceptional finish. The solid cast iron base, table and head are designed for production. The 2-speed oil bath gearbox transmits full power to feed rollers and facilitates fast speed changes at 24 and 31 FPM. The gearbox can be changed to 4-speed with the included gear to run lower speeds of 16 and 20 FPM. The corrugated infeed and fine groove outfeed rollers ensure a smooth feed. The precision ground and polished cast iron table rides on four steel columns giving it plenty of support for the larger workpiece. Heavy cast iron extension wings ensure a flat, smooth cut.

  • 5HP motor and 20" planing capacity for heavy duty work
  • Fully enclosed base cabinet with integrated casters for shop mobility
  • Cast iron table with extensions creates a big 55-1/2" x 20" working area
  • Four feed speeds - 24 and 31 FPM, 16 and 20 FPM with gear change - provide versatility
  • Feed rollers and cutterhead supported by full cast iron head assembly for rigidity

You have to see it to believe the cut quality and the sound is hardly noticeable. It ain't cheap but it's good. Setup was easy with no issues. It took longer to get it out of the crate than to assemble it. One thing I didn't like was there was no adaptor for the dust port opening to a 4in hose, it's an odd size for what's available.
Rockler's assistance in the purchase was also outstanding as I had some questions they had to go to the MFG for answers and they called me right back

Woodworking Experience:
While this is a very powerful planer, which will not bog down under a heavy load, I would not recommend it for a small garage or hobby shop. It's electrical requirements are the need of a 40 amp circuit with an additional high volume 5" connection dust collector capability. In addition, you can forget unloading and moving it around with your two wheel dolly.This unit from the factory weighs in at 911 pounds. The maintenance required for this machine is much greater than your typical bench top DeWalt, but regular maintenance on any machine should always be part of your daily operation. I had a Grizzly a few years back and ended up sending it back. It is nothing close to the quality of this POWERMATIC. For the larger shop owner, this is a great addition to you process.

Woodworking Experience:
Doesn't provide a smooth cut
I would expect a near perfect cut with a brand new machine. I purchased a jointer and planer at the same time. I get an perfect finish with the jointer, the planer chews the wood up. I talked to the folks at Rockler and they told me to contact Powermatic for help.

How long is the power cord that is included with/attached to the Powermatic 5 HP 1 Phase planer?
WoodlandJ on Apr 10, 2018
BEST ANSWER: It did not come with a power cord. I am a bit unhappy with the performance of this machine. I do not get a smooth cut. When I went to Rockler to try to find out how to improve the cut they didn't have a lot of answers.
