Machine overview

When you sign up, you can:


The JET JWJ-8HH is the largest (8-inch) and most sophisticated jointer made by JET. It is nearly identical to the JWJ-8CS, but upgraded with a helical cutterhead.

Helical Head

The Helical Cutterhead is a major upgrade, because the JWJ-8CS only has standard blades, whereas on the 6-inch standard model at least you have quick-set straight blades.

Spiral cutters are quieter and give better jointing results, especially on complicated grains. They are also easier to set up, last longer because of the 4 sharp sides and are cheaper to replace if one of them breaks.

More powerful than 6-inch jointers

It is more powerful than JET’s 6-inch jointers (2 HP vs 1 HP), and has more jointing capacity (8 inches), making it a very useful upgrade over the smaller models. Still, 8 inches is on the small side when face-jointing boards.

Dovetail base

The jointer uses a classic wedge-bed dovetail system over which the tables slide up and down. The chrome handwheels make it a lot smoother to move the tables than on many comparable machines. It also has a special rabbeting ledge.

The JET JWJ-8HH also has long cast-iron tables and a solid, rigid fence. The fence has three positive stops at -45, 90 and 45 degrees.

Replacement Cutter Inserts: It seems to be a bit tricky to find replacement cutters for this helical head, but we found some on eBay. They used to be sold on Amazon too, but they haven’t been available for a while now.

Machine Atlas Verdict

Reliable cast-iron machine with long tables and helical head cutters. May be slightly too narrow for most face jointing.

Value for money




What we don't like

  • 8 inches is still limited when face-jointing boards

What we like

  • Helical/spiral cutterhead for quieter and better jointing
  • Very long cast-iron tables
  • Reasonably powerful (2HP)
  • Handwheels to smoothly lower and raise the tables

    Can the fence body and fence bracket be removed to transport

    • Hi John, I don’t have the machine myself, so I’m not 100% confident, but I’m pretty sure that those parts can be disassembled.
