Tablesaw blades - sharpen or replace?

Does anyone happen to know if it's economical to have a 'standard' table saw blade sharpened? I guess it's a 12 inch blade.

I don't know how the sharpening services price these things. I guess it's by the tooth. A replacement blade seems to be ~$120, but I still need to remove the blade from the table. It's a single phase Makita.

Blades aren't that expensive.

Don't know what they cost to get sharpened.

My experience is that it is cheaper to buy a new blade. but there is a great range of prices in blades depending on the quality of the blade.
Have you considered sharpening it yourself. I use a dremel tool with a green stone. I guess that you could probably sharpen the blade in place if removing is a problem

They aren't that expensive if you want a crap blade.
Run with a name brand e.g. Irwin, Bosch, Diablo that specialise in making saw blades.
If it's got the potential to cause serious harm, don't skimp on a few bucks.

Irwin & Bosch blades are around the same price as the Toolshed ones on the link I posted. I don't know why the Toolshed hasn't listed them on the website because they do have those brands as well.

I just posted as an example that a new blade is going to be nowhere near the $120 that OP said.

A brand name basic 305mm 60T blade will set you back $75, a high end 80-100T will get up to $150.

They sharpen blades and also sell high quality ones, mainly Linbide.

If by standard blade you mean without tungsten tips then it is relatively cheap to get them sharpened, and not too hard to do it yourself.

Tungsten tipped blades for a Skilsaw are quite cheap. Mitre10 had one for $15, or two for $8, so I bought two!

Thanks team. I have three blades that need attention so I'll remove them and get the local sharpening service (PG2000) to take a look.

WRT blades being ~$120: I looked at Bunnings and the various blades were between $75 and $185, so not knowing which one I needed I just plucked $120 as a roughly in between price.

How many skilsaws use a 12" blade?

franken1, Jun 30, 3:52am
Nah, that's 16", not 12".

I just had a 32 tooth 12 inch tungsten tipped blade sharpened last week for $9. That waas privately. Saw shop quoted $17.00.

I thought that would be great for cutting the tops of fence posts. But at 14 kg it would not be a good idea to hold that above my head.

unclejake, Jun 30, 11:34am
Thanks Reggie. Even if it's double the retail cost for me it's still well worth while. I have all three blades in the car now so I'll drop them off tomorrow

zoopa, Jul 1, 12:20am
I am trying to work out if it would have an almighty kickback, or the sheer weight of it just makes it nudge.

But yea, not something you would want to use above your head.

zoopa, Jul 1, 12:21am
They can even braze on new teeth if necessary.

unclejake, Jul 1, 1:04am
^ In my case it appears that it is. One blade needs at least three new carbide(?) tips (I hit a nail when ripping some demo timber), but they tell me it'll still be much cheaper than new blades.

One interesting observation: They checked each blade to ensure they weren't the 'cheap ones' before accepting the job. Ha!

I'll update the thread with the cost when they are done later in the week

unclejake, Jul 3, 12:01am
It's clearly economical to sharpen a quality blade.

My invoice for sharpening three saw blades (one 9 inch and two 10 inch, including replacing some tips) was $88. I'm very happy with that.

That's less than you would pay for one new quality blade!

unclejake, Jul 4, 10:48am
It sure is. I'm stoked. Well worth it. now I I get to find out if all that noise and vibration from the table saw (under load) was because the blade was so bad, or perhaps I've stuffed the bearings (because the blade was so bad)

unclejake, Jul 21, 11:03am
. I guess I should have had the table saw blade sharpened earlier.

I tried ripping some elm yesterday and the noise and vibration is still there (under load). There's a little sideways movement in the blade so I guess I've damaged the bearings.

Oh well, at least it's a Makita and can be fixed quickly and (hopefully) economically

Its a bit of a revelation when you finally get the sharp blade back on huh. You don??
