About 3 years ago, I spent the money to go to a cold cut chop saw because I was tired of the grit all over my shop. They work great but the blades were killing me at $100 + a pop. Just to see what would happen, I sent a blade to a commercial saw sharpening shop. It cost about $40 and I've got a like-new blade back. Here in Connecticut, I use these guys: http://www.specialtysaw.com/bladesharpening/index.html They're great. They weld in new teeth, replace carbides, and the blades come back perfect. I have 3 blades and keep them in rotation. If you don't let them get too bad, the sharpening is pretty cheap. I'm sure there are plenty of places like this all over the country. Hope you guys find this useful. Best, Pete
It is also called "SPAM." But while we are touting our favorite products and services. I have a Piranha blade in my skill saw. I have had it in there since 2002 and cut lots of wood with it. I also managed to cut right through my steel saw horses and it still cuts like new.
Sharpening helps cut the cost for sure. Does your saw give you the option of running coolant ? If so that will add to the life of your blades a huge amount. I know the smaller cheaper cold cut saws do not run coolant and they can be hard on blades. Still beats the abrasive saws though, I refuse to use them anymore.
I agree on the abrasive saws ****ing..I hate all that metalic grit everywhere It will also **** up a cell phone in no time flat I went thru a few smart phones til I figured out the metal dust gets into the speakers and attaches to the magnetic voice coil and ****s them right up I take my chop saw outside the shop anymore when Im cutting up steel, I havent sprung for a cold cut saw just yet
We used to use them in our shop but the guys were to hard on the blades. I was having the blades repaired but kept losing teeth. I found out that steel blades use teeth with a different hardness and the guy fixing the blades could not or would not get the right teeth. I like the saw and I think a single user would take better care of it. The cuts were clean and no deburring. Now we use cold saws which are a lot of dough but worth every cent.
Spam is a lunch meat that comes in a can. No harm in someone telling about a favourable experience he had with someone that might help someone else save a $ or two. And he is not the owner of the business whose info he posted. Lighten up !!
"left the life for industrial design and publishing." Having been a journalist I know that you get your favors by touting a specific brand or company. Maybe he is totally honest and is just trying to do us a solid, maybe not. It remains to be seen.
Never thought about having a blade reconditioned, I think I must have pitched at least a half dozen blades by now because of missing teeth. There used to be few sharpening places here in San Diego, not sure how many are left though. Thanks for the heads-up.
I was in the maintence ,repair and operations supply business we used to sell mk morse blades I loved doing demos with the carbide metal devil chop saw and pick up a piece that I just cut off with bare hands and watch peoples jaws fly open thinking I was going to get burned another option for you check this web site http://www.mkmorse.com/products/index.aspx?product=74
We use cold cut saws at work, fluid fed. they are great, and we always get the blades sharpened, unless they break!(some heavy handed guys at the shop!) One thing I've learned, if you chip a tooth, change the blade as it usually leads to a broken blade if you continue to use it.
Call my comment spam if you want MR Pork and ******. Personally I think your blowing gas out your rearend !! If you do not have something worth while to contribute to the thread keep your opinions to your self. Now I do have a Mllwaukee metal cutting circular saw that uses a cold cut blade with no coolant. Very handy saw for cutting rectangular tubing for frame fabrication in my small home work shop. Works good for cutting steel plate also. Blades will last a long time. I have found cutting rusty metal seems to dull the blades quicker. The saw cost me about $250 5 years ago and the blade are about $70. I have bought 3 or 4 replacement blades. I was not aware that the blades could be repaired or sharpened. The saw works much better then the abrasive cut off saw I have.
I work in a sharpening shop in London Ontario Canada. Called ETK Carbide tool inc. We change broken teeth, plus hammer blades if bent.
I am just a curious observer, but how many cuts do you get out of a blade, say on 2x3 tubing with 3/16" wall before you start noticing missing teeth. I would be insterested in getting one of these if you didn't have to replace a blade every month. I am just a hobbyist, not production user. Coolant would be a consideration, but without coolant how long does a blade last?
Hi Willy301, I've never really kept track. I read on another forum that somebody gets about 200 cuts and that sounds about right to me. You can feel the blade go south. It still cuts, but it's not as easy and if you look at the carbide teeth closely, they're pretty blunt. I like to send a blade in to get sharpened before it gets too bad. If you start knocking teeth off the price goes up in a big way. The last round, I had one blade that was just dull and another that I knocked a tooth off becasue of a bad set up. The straight ahead sharpening cost about $35, the sharpening and blade repair for the bad blade cost about $70. That's still half of what I pay for a new Morse blade which is what i use now. Here's a picture of my chop saw set up. There's a piece of 5/16" wall square tube in the photo that I cut at a 45 degree angle. It's straight and 44.5 degrees which is good enough for the stuff I do.
I would like to know what your intentions are is all .... and will you respect us all in the morning .... it will take more that three posts to figger that one out! lol Are you married to the saw bade company??
A guy asks a question and I answer the question. I've got no connection with Morse or the saw sharpening company. What's the issue here? I'll say the same thing to you that I said to porkand******. If you can tell me how to make money off this post, let me know...
There seems to be some confusion about the three types of saws we are talking about. First is your basic chop saw with an abrasive blade. Kind of crude but inexpensive and will get the job done. Second is basicly the same saw (different RPM) with a carbide tipped blade which gives a very clean cut. Third is a cold saw that uses a blade that looks like a round hack saw blade and requires coolant. The cold saw leaves a very clean cut but is quite a bit more expensive. I like the carbide saw but it requires a lot of care by the operator.
If you check out a cold saw blade it has a square tooth and an alternating round tooth, and that's how it removes material, all the while moving at a very slow rate, 60 to 100 rpm, if memory serves. Works really well.
They make the blades 5-3/8 dia, to fit you cordless circular saw to 14" dia 7" turns 3500 rpm max....14" 1300 rpm max....koool stuff.... http://youtu.be/AbslZuJ7gsI
So thats what happens to my phones! ha. Yeah i have to use a magnet to pull the metal particles out of the speaker all the time
