  • Knife size is 12 x 1/35 x 1/8 inches
  • Cutterhead diameter of 2-3/4 inches

What Could Be Improved?

  • No option for 115 volt – prewired at 230 volts
  • Slightly heavy at around 600 pounds

What Else Might You Get With It?

  • Jet 708119 JMB-UMB-HD Universal Mobile Base (on Amazon) – Shipping weight is 600 lbs. Will definitely need a separate mobile base to move this jointer around after set-up.
  • This jointer runs on 230V – make sure you have that capability in your workshop (220V breakers etc.)
  • Dust collection system
  • Dust port reducer

  1. I have had mine for 6 years. Done a great job for me. There is one flaw that I have found. The guard that protects you from the blades is attached to the unit with a inadequate bracket that seems to be made of pot metal. I bumped the guard with a board and the bracket shattered. This has all the force from the long arm and shield focused on it. I removed the bracket and tried to order a replacement, but only the complete assembly is available for purchase. So, to fix my issue – instead of replacing the $20-50 bracket – I am required to purchase a $200 assembly. On top of that, they are back ordered for months. Apparently, this is a common problem that they cannot keep up with.

    • Thanks for the information Rick,

      Unfortunate to hear about the bracket/assembly issue. 6 years is a great return though for any machine.

      I’m yet to come across a jointer or planer that is perfect – but it would be great if JET were able to look at this sort of feedback and see if the design can be improved.

      Back orders might be harder to deal with – companies usually only have a set amount of resources to allocate, and anything that is quality takes more time to manufacture.
