Default 8-inch jointer--carbide or HSS

Hi Ho: This seems like a good place to ask whether the carbide cutters do a better job than the replaceable HSS on jointers. I'm about to buy a Grizzly jointer and for about $300 more you can get carbide. Is it better? I do mostly cabinets and some furniture.

Also they have an older model with a 2 hp motor. Is the 3 hp motor really better? Does it matter if the cutters are carbide or HSS?

Thanks, Dirk

Hello Dirk! I do not have one, but it should cut better with out getting dull as quick. Most people use the HHS blades still, They work OK, for me. If i had the money to put into extra blades, i would go for it as well. I have no problem with power,Dirk, but mine is a 6 in. Delta. It may be worth the extra money, i don't think you will regret doing it. Good luck.

I have the G0593 8" Jointer w/ Spiral Cutterhead. I wanted to get rid of all the hassle of adjusting the knives. I will NOT go back. I would rather not have a jointer than not have the spiral carbide cutters.

I find it WELL worth the money. Also, the cut is smooth and the cutters stay sharp for a looooooooong time. I"ve run a few hundred board feet through them and I still haven't needed to rotate them yet.

Hi Ho Mark: Thanks very much for the first hand report. The 0593 is just an 0586 with a spiral cutter head if I have it straight. They are currently being phased out, but if the 2 hp motor is not too small I would like to get one anyway. Do you find the 2 hp motor is underpowered? Would the 3 hp motor on the newer one be better?

I like the 0593 because the mobile base is not built in and I think it will be easy to raise the height to 34 inches. This is the height that everything else is at in my shop and will make it more convenient if I ever want to run long boards etc.

Thanks again, Dirk

I Dirk,

I do suggest you get the spiral cutters. These are far better than the knives.

I have heard great things about the spiral cutter. Sure is a lot of denaro, but when you are getting what you talk about I'd go the spiral cutter over the 3HP. BTW I do not know the price increases of the Spiral cutters and the 3HPis but it will never be less than they it is right when making the original purchase. I too have the Delta joiner and it is great but all I use now is rough cut so I will want to get a much better joiner and planer some day.

Sorry for not seeing this earlier Dirk. I got your PM but I'll go ahead and answer it here.



You're right about the 0593/0586 thing. One is with the spiral head and the other is without.

On paper, the 4" per 1 HP rule does theoretically seem to be stretching it but I don't find ANY problems with the power. I only make light passes anyway but I think that because the cutters cut so easily, nice and smooth that you can stretch the rule a bit. I have no hard math to back that assumption up but, again, I haven't had any trouble whatsoever planing maple, walnut, oak, cherry, poplar or fir. In fact, if you're careful and take light passes, you can even plane cross-grain, with those carbide cutters.

HSS is initially sharper than Carbide. You can sharpen HSS youself.

Hi Ho Mark and Mike: Thanks for the inputs. It is especially valuable from someone who has used the same jointer. So thanks again Mark. I think the only disadvantage to the spiral cutter is that I probably will want to get a planer with a spiral cutter after not having to put in new knives all the time.
