Cutting discs

[eyecatcher]

Does anyone get full use from a cutting disc?

I mean  its still 9inch diameter when its just about redundant  without jacking up the steel considerably.

 

Got a few like this and loathed to throw them away.

The local steel shop has it sorted.

Nope, that's about it for a chop saw cutting box

If it still cuts without burning, what are you worried about?  For me, it's when the cutting, drilling, whatever starts sending up smoke that it's time for a new one.

It's a chopsaw blade. The design of most chopsaws means you loose cutting capacity on items like box steel. The smaller the steel the more blade use you'll be able to get.

 

What pisses me off here is builders using 1mm 4" discs for grinding. I've had a few shatter on me when cutting with a disc some <deleted> used for grinding.

Wwhat i am saying is, when the disc has worn 2inch the chopsaw is unable to pull down far enough to cut thro anything .....unless you prop your steel up on packers which is dangerous.

Which is what I just said above.

Rotate the job in the vice.

Then depending on hole diameter you might be able to use in a 9" grinder if you have one.

yes I was also clarifying for the posters before you

Does the saw have a stop?

The belt-drives cost a little more, but generally use more of the blade...

yes chop saws will generally have a two position backstop and moving from the back one to front helps.....but really most people i reckon are using the front one all the time.

 

Really 50pc of these blades are wasted but at only 100bt a piece its not a big deal is it....

Maybe it has a use for sharpening drills when its steel cutting days are over.

WARNING - Risk of injury 

 

Follow up to my previous post showing a carbide steel cutting blade.

 

Do not be tempted to fix a carbide blade to an abrasive disk machine because the rotation speed will be too high.

And a down-stop that is often adjustable...

I have switched from a chop saw to a good quality dry cut saw.  The teeth are carbide and should last for a very long time as well as giving a much nicer cut.
