saw

[wroughtn_harv]

I'm not sure what the difference is VIN but DeWalt has made a completely different saw for the steel blade versus using the carberendum (sp) one. So you might find out that your blade won't work in your chop saw.

I have three chop saws. I hardly ever use any of them. The biggest reason is I rarely if ever do production work. And the sparks are not only dangerous but they're like cigarette smoke. They mess up everything they touch. /forums/images/graemlins/frown.gif Heck, in my old age I'm getting where I don't even like using grinding discs in my angle grinders if I can get away with using flap discs, again sparks.

What people don't keep in mind is those sparks are like acid on glass like in windshields etc. And they can destroy a paint job instantly. Another thing is the sparks land where they can be subjected to water and then you have rust stains. These can be a bear to remove from tile, concrete, auto paint, etc.

I had one job where the company doing my core drilling around a pool got to pay for an acid wash because they allowed some sawdust from rebar in the decking to get into the pool. It didn't show for a week or so and then there were these stains. /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif

If it was all so simple then everyone would be doing it...... /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Harvey
My main motive in buying this disk is because

(1) I have had enough of breathing the crap from Carborundum disk.

(2) Carborundum disks make a hell of a mess in the shed.

(3) 9" carborundum disks are not cheap here in oz $3.75 bulk or $4.50 retail (roughly speaking)

I use the new disk this morning playing around. One word at this stage BRILLIANT cuts clean and so fffffffffffffffast /forums/images/graemlins/grin.gif

The building maintenance crew at work says you have to buy the new saw to run the 14" blade because it is designed to run at 1500 RPM which is about half what a chop saw runs. They claim it makes fast clean cuts with no sparks. The blade lasts 4 or 5 times longer than standard blades. The saws with blade cost five or six hundred. Replacement blades about $100.

I found the cheapy dewalts really useful for cutting bundles of steel studs (10 at a time). I cut about 1,000 of them on a blade and it was much faster than snips & easier on my paws.

I also cut the plate for my welding table.

Not the greatest, but it worked. Wait 'till I get my plasma cutter ...

</font><font color="blue" class="small">( Bought a 9" rotary hacksaw blade (48 teeth) today to put in my circular saw . has anyone used them, are they good or bad, is there any special idiosyncrasies. cost $130 au. )</font>

Sounds like a cold saw, which is meant to run at low RPM, low feed rate, and used with coolant. Should last a long time if treated right. If you see sparks or blue chips, shut it down. It's self-destructing.

No coolant required and they run at a range of speeds by there website
"The ROTARY HACKSAW from Austsaw delivers a precision saw blade for every-day use in angle grinders, power saws, drop saws & even radial arm saws."

I cut a few pieces of steel with it yesterday, some 2"x2"x 3/8 angle iron, it cut this as easy as cutting a piece of pine 2"x3" with a circular saw. It cuts 3 times faster than a carborundum blade in an angle grinder, and very little vibration.
I will keep folks posted with an ongoing report but so far, GREAT

I am a $130 poorer
My blade is toothless
My excitement has gone and i just want to sit in the corner and cry. /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif /forums/images/graemlins/blush.gif
I guess i am a little richer in some way for the experience.

Poorer and wiser, Vin's poorer, we're wiser.

But appreciative!!!!!!! /forums/images/graemlins/grin.gif

How many fiber blades would you have used to the same amount of work?

What do you think the cost per cut was if you can guess?

And was it worth the extra expense to be sparkless and dust free?

After all, for some, sparkless and dust free is worth almost any price. If you were one of those would you consider the steel blade a good investment?

Sorry for all the questions. But who else do we know that has the answers but our wonder from down under?

Probably 5

<font color="blue"> What do you think the cost per cut was if you can guess. </font>
Lots



<font color="blue"> And was it worth the extra expense to be sparkless and dust free? </font>
No

I think had i put it in a cut off saw it may have been a good investment but to use it in an angle grinder or circular saw they simply will not last as lateral twist becomes the enemy.(i hope you get my drift).
one other point, we all know how dangerous any cut off wheel can be. Well i would put these at the top of the list, the shaving that fly of are so dangerous, glasses alone are not enough a full face shield is required. I am still pulling shavings from my cheeks
