Hi Guys and Gal Wood Working Buds. I need some info quick. I am looking to buy a tool to that is efficient to use to sharpen our planer blade knives.

What is the best tool we can get, that will do the job we need it to do…..and won’t kill us at the check out???

what planer are you using?

if you are using any of the smaller “lunchbox” planers (bought at home depot, lowes, and similar hardware stores) chances are they only use replaceable/expandable blades (except for a select few like the older Dewalt 733 I believe) and as such cannot be sharpened.

you can try honing them using a very fine stone or honing compound just to clean them up a tad, or maybe use some cleaner to remove the gunk from the green lumber, but that as far as those go.

Now, if you are using a 15” and larger stationary induction planers, than there are a few jigs on the market (even posted here) that can easily sharpen those blades. there are also commercially available sharpeners like the wet grinders (Tormek / Jet/ Grizzly/ Sheppach) that have adapters to hold planer blades for sharpening.

We are using a dewalt 13 inch planer. I would like what ever I buy to be able to handle 20 inch blades because I have my eye on a 20-inch planer I want later. I am wanting a jig of some sort. I was looking at a tormak, but the sales person we talked with said they didn’t have a planer jig for those??? I would like what ever I get to be able to sharpen my wood chisels as well.

I have a Tormak equivalent (Sheppach) which does chisels, handplane blaes, scissors, knifes, axes, and anything with a cutting edge to it. there is a planer blade attachment which is the same as the Tormek one. maybe the salesperson meant that they didn’t have one in stock (as surely Tormek has those attachments)?

As for your current planer – the dewalt 13” planer (735) only uses replaceable double edged blades (each blade can be swapped to be used “twice”). so no real option to sharpen them – but you could try cleaning them and see if that helps.

here is the tormek part (not cheap stuff):

yes I understand. see my comment above – you cannot sharpen blades for that planer. you can only use each blade twice before having to replace it with a new blade – those are expandable blades.

If you intend on replacing the planer with a larger one that uses blades which can be re-sharpened, here is a cheaper alternative to the Tormek:

with the planer blade sharpening attachment:

I went to wood craft, I was going to shell out the bucks for it. But the guy didn’t act like he knew what we were talking about and said they didn’t have a jig for it. Believe it or not. I was surprised because I thought for sure tormek would be the one to buy, and apparently with what you are telling me I was right.

But I may just end up buying the planer sooner than planned. What is your suggestions for that?? I am not happy with the dewalt that we purchased. It has lasted, we got it when we built our house. But it is sooooo slow, and alot of the times had to push the wood through it.

I checked out the Grizzly…...is it as efficient as the tormek? Price wise I do like it alot better. But wondering will it do the same job and hold up to the Tormek? I love it in here, if I have a question about something you all are such of wealth of information.:)

actually – that’s NOT exactly what I’m saying – all I’m saying is that there are alternatives to different people out there. the Tormek is still the best unit out there, and is rated for heavy duty where as the lower cost alternatives are more aimed at the weekend warrior that use it less frequently and don’t necessarily need to fork out the high $$$ value for a Tormek.

That aside – to focus on the planer, From your description, I would highly recommend tuning your planer to perform better. the Dewalt 735 is a fantastic and VERY capable planer! if you are having difficulties with it, it may suggest that it is not setup properly, or in need of a tune up/ cleanup (bed needs to be waxed smooth, rollers need to be brushed clean, blades need to be replaced if dull). If the issue is tune-up , then you might end up getting the same poor/dissappointing results even with a larger planer with less $$$ in your pocket if not maintained and tuned properly and regularly.

just my 0.02$

Have to be careful sharpening those. Too mucch grinding and the cuts won’t be even.

Could you use a spiral head on the planer and completely do away with the knives? If you’re gonna spend the money id say that would be the ticket.

Robin – yes that is the one. it is identical to the Grizzly (same model sold under different name/color) – so whichever one ends up costing less would be my choice.

Chrisstef brings another good point – going with a helical/spiral cutterhead (either in a new planer, or you could retrofit an aftermarket cutterhead on your existing dewalt) would eliminate the need to sharpen planer blades and will also give you a quieter operation.. the cutters on those are usually carbide and will last much longer than HSS blades (your current blades). these cutters usually have 4 cutting edges (compared to your current 2) so the overall long term usage of each cutter is much much longer than you are used to at the moment – however those are also replaceable.

Based on your OP – you would still be looking at a sharpening grinder for your chisels anyways. so see my first paragraph for that.
