Tablesaw power conundrum!

Hi everyone,
I’ve recently got a new tablesaw, it’s my first one.
It’s a small, portable 900W tablesaw, kind of small but it fits my shop well:
Tablesaw

The thing is, I want to cut some 4cm thick (~1.57 inches) Korina wood:
Korina

I’ve only used this saw a little bit and it’s already lost 2 teeth on some pine (!!) so I’m not sure how it will do against thick hardwood. I’ve read that the blades that come with the saw are usually very low grade, will changing the blade make a difference? I don’t want to try and cut the Korina only to find out mid-way that the saw is no good for this kind of work.

If anyone has any experience with these little saws, I’d really appreciate the input!
thanks,
Ron.

Ahlan Ron,

there are 2 things to consider here:
1. blade quality
2. tablesaw/motor power

the factory blade is mostly junk, get a better quality blade and the cut quality will be much higher – also the blade will not break like yours did – if you can, get Carbide Tooth blade.

As for the tablesaw and motor power – if it’s underpowered, it will not be able to cut through thicker materials, and may get stuck half way with the saw not able to keep the blade spinning, but it will not damage your blade.

bottom line, I’m not familiar with the table saw model but cutting through 1.5” material takes a load on the motor. regardless – you should get a better blade for your saw.

hope this helps.

agree with las coment, go for a new good quality blade and try it using several passes… also check temperature of the blade and if you are burning the wood…

Also tray to use a splitter whe you make your cut, that will release presure from the blade and contribute to an easier cut

I am going to say your saw is underpowered, but I wouldn’t get rid of it, I am sure it will be great for smaller projects. As for cutting the korina (I am not familiar with that species) I would try to cut it using a new blade and multiple passes instead of just one pass. Good luck

Oh by the way my tablesaw quit and I bought a $150 used Craftsman off of Craigslist. Its cheap and underpowered but it works for me. If your saw works for you, then I say go for it.

Hi Ron. I see you are just beginning your woodworking journey. Most of us have done the same, buying tools that we hoped would be ok, but just couldn’t do the work we expected. If you are on a budget and/or have limited space, I would suggest you buy some decent hand tools and learn how to use them. Later when you have more space and/or money you can buy some quality machines. Size is not the determining factor. You can get high quality machines that are small and they will perform well within their limitations. This is something most of us learn through experience. Low quality tools will only take the joy out of woodworking for you and leave frustration in it’s wake. I hope you don’t resent my comments here. I have had to learn this the hard way and I don’t wish it on anyone else. Tool can look alike, but like people who look alike they can be completely different in quality.

Well, I thought as much about it being underpowered but I have to admit, I didn’t think of cutting it in stages…
I hope a better blade will produce better cuts but I think I’ll use this tablesaw only for cutting ply and MDF.
Thanks for the replies and advice, no resentment here stefang – good advice is always welcome!
And toda raba to PurpLev!

I think that a quality thin kerf blade would really give this saw a leg up.

Yes I agree with Tim. I mostly use a 1.7mm (5/64”“) Tungsten Carbide tipped blade in my tablesaw, rather than the usual 3mm (1/8”).

This gives two benefits

1. Less stress on the motor.
2. Less waste due to the blade width (I do a lot of small stuff with exotic woods so less waste is better).

If you’ve already lost teeth from the blade , it should go straight into the trash can , before you lose an eye !!

Do you have any additional info about the saw , like blade size for instance ? How about a link to your saw or the manufacturer ? What stabilizes the saw while you are using it ? The base looks pretty narrow in the picture that you’ve posted here .

I really know nothing about this saw other than what I have seen here. At only 900W it has to be low powered.

You could benefit greatly from a thin kerf blade. There is now a very thin kerf blade available in the US. The kerf is 1/16th of an inch. I don’t know if you can even get this blade where you live and I don’t know if it would fit your saw. Furthermore, it’s expensive ($175).

Nonetheless, here it is – -

I’m seeing a disaster waiting to happen. You say you lost 2 teeth????? Stop using it right now!! Those teeth from a cheap blade are a missile that could kill you!
Also, I hope the fence is not that badly aligned as it shows in the picture. If so, you’re in for a major “kickback” that you don’t want to experience——-ever!
The base looks like the saw will tip over any minute.

As soon as I saw that the teeth were chipped, I stopped using the saw – it’s been sitting idle for a while and the fence got misaligned when I was moving the saw. I should have put up a better photo, the saw has a metal “cage” that you can’t see in this picture, that acts to stabilize it, so it’s pretty stable when in use.
I was going to have to get a new blade anyway, I’ll look for a thin kerf blade – it’s an 8 inch saw by the way.
I can’t seem to find a manufacturer site, I think that’s because it’s a sticker name – Wolf.
Thanks for the tips and concern!
