Chet Posted April 25, 2020 Share Posted April 25, 2020 I am having to replace my Jointer knives. I have been looking at both HSS (about $40 a set) and Carbide Tip (about $100 a set). Do you guys have any opinions one way or the other?

Woodenskye (Bryan) Posted April 25, 2020 Share Posted April 25, 2020 How long has this set lasted? If you think you could get 2 times longer with carbide then that might sway your decision. If it was me 1 would buy 2 sets of the HSS. 1 Quote Link to comment Share on other sites More sharing options...
Kev Posted April 25, 2020 Share Posted April 25, 2020 I’m surprised that you need to change them already. Doesn’t seem that long ago that you got the machine? Good advice above! Quote Link to comment Share on other sites More sharing options...
Spanky Posted April 25, 2020 Share Posted April 25, 2020 We have a guy here that sharpens planer knives, jointer knives, band blades and he sharpens my edger blades. Quote Link to comment Share on other sites More sharing options...

I don't know how it happened but the first inch or so, closest to the fence looks like the blade on a scotch tape dispenser. Last project was the morris chair and I know I would have seen that if it were there during that time. Then a couple of weeks ago I went to mill a piece of oak for my neighbor, my wood but I was milling it up for him. When I made the first pass there was about nine parallel grooves down the length of the piece. Each groove was about 1/32 wide. Looked at the jointer blades and the blade was damaged with that pattern. I have had the machine for two and a half years now. 1 Quote "Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for." - Epicurus Link to comment Share on other sites More sharing options...

I was hoping to have the dough to by a helix head by the time I had to replace the original blades.

Tmize Posted April 25, 2020 Share Posted April 25, 2020 I like hss to me in normal (not highly figured) wood you get better finish. That what I buy for my planer. To answer Spanky all the shops local to me charge about the same to sharpen as I can buy new blades for. I have done touch up sharpening before on my planer knives. It works that not if they are chipped. I’ve heard carbide blades leave a rougher surface due to them not being as sharp but last longer. Is there any truth in that?

Thats the same reason I am replacing and not having them sharpened. My same sharpening guy is real reasonable with saw blade sharpening prices but it didn't make sense to pay to have the jointer knives done. 11 minutes ago, Tmize said: I’ve heard carbide blades leave a rougher surface due to them not being as sharp but last longer.

Some of the reviews I read said something along those lines. 1 Quote "Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for." - Epicurus Link to comment Share on other sites More sharing options...
Spanky Posted April 25, 2020 Share Posted April 25, 2020 I like the helix head. I have the 20” Powermatic planer with the helix head it works good. Quote Link to comment Share on other sites More sharing options...
Coop Posted April 26, 2020 Share Posted April 26, 2020 Chet, have you looked at Infinity blades. I haven’t had to replace my jointer blades but use them on my planer, per RichardA’s recommendation and they last longer and sharpen well here at home.

Yea Spanky that would be my first choice but I just don't have the money for that at this point. The little gig that I have that creates disposable money for tools is dead right know with the shut down. 55 minutes ago, Coop said: Chet, have you looked at Infinity blades. Yea that is the company I have been looking at Ken.

Kev Posted April 26, 2020 Share Posted April 26, 2020 Curious what the price tag is for that cutter head? Quote Link to comment Share on other sites More sharing options...
Chet Posted April 26, 2020 Author Share Posted April 26, 2020 Byrd's are $469 for an 8 inch. Thats the only brand I looked at because that was enough information to tell me the search was over. ?

Chet Posted May 11, 2020 Author Share Posted May 11, 2020 I finally got around to changing out the blades yesterday on the jointer. My first impressions of the Infinity blades are good. the lumber seems to come off with a nicer finish the the OEM blades. I could probably do this 3 times faster next time know that I know what PM actually meant in the instructions. Part of the problem was that one of the diagrams didn't print properly. But knowing what I know now, the process for changing to the HH would be faster then this was. 1 Quote "Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for." - Epicurus Link to comment Share on other sites More sharing options...

That's why we tend to try and stretch ourselves in projects! By stretching yourself, the next time you have to do it, it's just not quite so daunting! Glad you got the jointer straightened out!
