circ saw

[gar2191]

I have a cheap Milwaukee power saw. I used it this summer to cut a lot of hardi plank.
It was rough. I had a tile blade on it. Did the job.
Now I notice this with the wood blade back on.....
It starts the cut with ease...better than it was before ,dont know why that would be but within a foot it starts to pull hard to the left and wont come back.It can screw up a cut by a half inch really fast.
I dont notice a lot of play in the blade..but I dont have anything to compare it to.
What does this sound like to you???

Sounds like it's time for a new saw.

If you were cutting abrasive material with a dry saw the bearing will pick some up and get trashed. If you are cheap and handy put a new arbor bearing in I have routers that are over 25 years old on their 3rd or 4th bearing set.

Sounds like the blade is heating up. What type of wood are you cutting, how thick is it and what direction are you cutting (ripping or cross cutting)?

 

[neophyte]

Is there any chance the depth adjustment got bent, maybe out of alignment with the sole?

sounds like the kerf of the blade to me. not sure what else could cause the saw to do that.
try another blade & see what happens

Could be 1 of 3 things.
- bad arbor bearing
-warped blade
-base is either bent or flexing

When you nick a nail and take the points off one side of the blade's teeth it will go in the direction of the good teeth. Could be the problem.

The proper blade for cutting the cement board would have much easier on both you and the saw. I second either a dull wood blade or damage to the arbor bearing.

I JUST went through this the other night cutting a piece of oak floor out of a trailer. I hit some nails (not supposed to be there) and had the same issue when I went to cut the new material. I changed out the blade and it cut fine. It could easily be the blade.

wrong blade

Your doing it wrong try getting this puppy square

Eithier the table is bent or out of square. or you hit the nail with the blade and chipped a tooth at some point in time it's possible maybe you didn't do it and that it was a flaw but it'll cut to the left of the right just like a chainsaw with a bad tooth

Square it up check the teeth and the bearing slop and try again

Try a different blade first. One slightly bent tooth will make a saw pull to one side.

Cutting cement board is VERY hard on saws, especially direct drive ones because the motor and bearings are right there in the dust cloud.

You used a tile blade? Hmmmm. You really need a blade for cement fiber board. They have 4 diamond coated teeth. Anything else just isn't up to the task for very long.

I keep an old circ saw in the drawer here with a hardi blade on it. Saves my good saws. Get an old one cheap and a thrift shop or somewhere like that and save your good saw for wood.

the tile blade was layin around and it worked good. But I did work the saw too hard. This saw will be my junker from now on.
btw what is a good carbide general blade under 20$..??

Frued 24T or the Demo Demon if you're going to be hitting metal.
