I am ready to upgrade my Jet Jointer to a helical cutting head, but the cross reference table in the Grizzly catalog seems to have a typo and lists:

Jet does not make a JJ-6C5X and mine is a JJ-6CSX.

I talked to Grizzly who said the reference table came from Byrd and I should contact them. They are closed for the day, as is Jet. Using the Jet part breakdown it looks like the cutting head assemblies are identical between the 6CSX and 6CSDX except for the blade holder itself.

Just wondering if anyone has indeed put a helical head in their JJ-6CSX and what model they ordered. Tomorrow I will be able to call Byrd and Jet and hopefully get to the bottom of this, but doesn’t hurt to ask.

That is definetively a typo, the JJ-6CSX and JJ-6CSDX use basically the same head configuration the difference being in the knives and the mechanism they use to hold them and adjust them in the head.

The byrd website offers more insight onto the situation, they only make 3 models of 6” cutter heads, a generic one and 2 specifics for Powermatic jointers.

I also own the JJ-6CSX and am seriously considering investing in one of this units and it seems that Grizzly has by far the best price around.

Another option I am considering is ordering the replacement knives from Freud.
I found that they will cut the knives to my specs for free so that if I order 1 C100 (25” X 5/8” X 1/8”) and have it cut into three 6-1/16” lengths that should cost about 1/2 of what the Jet knives cost.

The drawback to that is that you can’t order them online.

I also found a manufacturer that makes Tungsten-Carbide tipped knives for the Jet and the price seems affordable, model CT006 at $86.00 for the set of 3.
They also provide T1 HSS steel knives (18% Tungsten) the prices again seem very affordable.

Their website is:

Have fun….
