That one bit of info that you can use a "worn out" abrasive chop saw blade came at the right time. I just receive my 7"/9" large angle grinder just yesterday. Now I have something that I can use with my worn out blades.
Great tip on roughing up edge with a piece of 1” flat while it spins super slow. Had 1 cut (2x2 square 1/4”) that took 30 min because it became glazed and didnt know. Then found your video lol Cheers from Colorado
Quality abrasive blades are worth it. Much higher production and minimal burr. Here in Australia I use PFERD 350mm x 2.8mm x 25.4mm for up to 5mm thick sections and get a lot of life from a blade. Cut pressure and surface velocity matter a lot. The blade needs high surface velocity to work. If the rpms drop, pause for a tiny moment and it makes a huge difference. A worn down blade also has less surface velocity and can compromise cut speed and quality.
@@cleanmachine08 yes definitely a quality blade makes a huge difference but price isn’t the only indicator of quality. And having a cap saw where you could speed it up as the blade wears down would be helpful, but I don’t know of any
Great video Darren. I have a Makita 14" chop saw and when trying to cut 45 or 60 degree angle cuts in square tube always get a bevel which makes it hard to get a good joint. You mentioned this in the video - how would you recommend cutting angle cuts without a bevel? Is it possible with an abrasive chop saw or do you use another tool for angles? thanks!
I should probably make a video on the subject but normally I just use A angle grinder on all four sides or even better a metal cutting bandsaw depending the wall thickness of the tube being a plasma cutter can work well as well.
A video comparing the pros and cons of different ways to cut mitres would be good - cost, accuracy, speed, burring, consistency etc.. I'll try the angle grinder on all four sides - I've tried using the grinder from one side all the way through and its not good. thx.
It should cut fine but it may not leave as good of an edge and if you try to weld it if you have a blade that's contaminated with other metals it may cause trouble so if you're going to be welding the pipe after cutting it I would consider using a new blade.
I work in a sheet metal shop, we use one of these to cut angle, pipe, and sheet metal forms. The last couple years, there has been a terrible burr that is like a 1/2” long razor blade, it wasn’t too bad years ago but I noticed as time goes on they are getting ridiculous, could it be the blade? Cutting too fast?
I am not sure. but there are quite a few different manufactures of blades you may want to try a few and see which one works better or if it's something to do with cutting speed or material has changed slightly over the years
Hello there. I'm from the Philippines. Just wanna ask about the abrasive disc I bought for my cut off saw. It does not cut easily to metals. What could be the cause? Could it be that the disc is too thick or because my cut off saw is only good for wood cutting?
I’m getting a lot of burr on my cuts on 20mm tube. I have a Makita abrasive saw which is new. Is the material too thin perhaps? And the cut is not square, I have tried different speeds etc
Big burrs are pretty normal they often can be reduced by cutting faster. I haven't had really any issues with un square cuts I can imagine you have check the fence already.
@@KingKong-jg6pd are you trying to cut 90° angles or are you trying to cut more like a 45? I have never really had trouble cutting 90s with an abrasive saw but cutting 45s can be very tricky to get them to cut straight without making a bevel. Some people say a higher quality blade helps. I haven’t found one that completely gets rid of the issue though that’s one of the reason that people use metal cutting band saws or the more expensive lower RPM carbide saws.
I've had the DeWalt cold cut for 15 years and love it. However, the new Milwaukee fuel has a free 12.0 battery promotion about to expire. I'm trying to find a reason to buy it. Ha! One thing I like better about the Milwaukee is the soft start. The DeWalt has quite a kick and can trip breakers.
Also, a Milwaukee seller I buy from is unloading his inventory of these. $200 plus shipping. If you're interested, I'll point you in the right direction. (bare tool)
90° cuts tend to do quite well and accurately but when you start doing angled cut yes they tend to have the blades start wondering. if I need accurate angled cuts on tubing I'll either mark all 4 sides and use a angle grinder to cut all 4 sides or use the miter bandsaw also with an adjustable square and a plasma cutter you can make very quick work out of tubing some people like the evolution cold cut saws but I have found their blades to be too expensive for the amount of cuts I get out of them.
@@CreativityUnleashed i see. thanks for the tip! i recently got into fabrication works transitioning from woodworking so i was just wondering that maybe its normal not to get perfectly accurate cuts as i could get from cutting a piece of wood on my tablesaw. the gaps or inaccuracy doesnt matter as much when i started welding the joints. and also i just learnt that im gonna need a fixture table to avoid getting my work all warped after welding.
@@MuraiWoodworks yes without a fixturing table it makes it a lot more challenging but there are techniques with welding that will greatly reduce issues and understanding which way the Metal is going to pole towards is quite helpful!!
I need to cut some painted 3x3 11 ga tubing so I'm concerned that an abrasive blade would create too much heat. If I took my time and made small cuts and allowed it to cool between cuts, do you think I could avoid overheating the tubing?.
Why is no one talking about using a mask with these abrasive chop saws??you mentioned the dust. It has a warning label on the blade its self.to use a resperator. Permanent lung damage!i see you wearing a mask👍👍👍

Before watching any videos on the Cold Cut saws
I thought of the cost - life of their blades.
Abrasive chop saws are just fine for me
thanks
Excellent info and tips!

How to hit the blade if it is not cutting the metal and taking a lot of time
Please post a video showing that
Blades also come with an expiration date on them. Thanks for the upload
Is it a smaller than 14 inch blade on the saw with an aluminum cutting blade?

@@CreativityUnleashed thanks. Yah its a new blade. Most people seem to be using band saw. Much more expensive tho
Whats a good disk using a Milwaukee 14" chop saw to use for cutting 3/4" black steel pipe?
Since the blade is 14" can this type of saw cut a 12" x 12" x 1/4 sheet of steel in half?
@@kennethmeese I don’t think so. You would probably be better to use an angle Or plasma cutter

If your chop saw is designed for wood often the motor capacity and RPMs are different
but I'm not sure exactly what you have.

Really helpful. Thanks!
Can a Dasamon disc be installed on a Dewalt machine?
you would need to check the RPM rating of the blade

Cold cut chop saws are far superior 😑

Definitely a good idea to wear a mask !!!
