Just a note - when cutting, you do NOT want to let the machine always cut at its own pace. When cutting wide sections, such as the start and end of RHS, you need to provide down pressure to ensure adequate chip loading on each tooth. If you don't, the teeth will tend to skate, causing the carbide to heat up and become blunt. I have a version of this saw made by Fein and they are quite specific about this.
@AutoExpertJC
@AutoExpertJC Жыл бұрын
Yeah - perhaps I glossed over that. I did mean not forcing the tool. Agreed that carbide likes to be worked reasonably hard. The saw is certainly not as happy when more teeth are engaged.

Do the blades in these saws have anti-kickback shoulders? I'm assuming this would limit the risks of too much force being applied. I'm not suggesting that it makes this a non issue or that you shouldn't worry about it. You're still going to induce excessive frictional heating of the blade and other issues, but at least it mitigates some of the risk of all that angular kinetic energy being rapidly dissipated in undesirable excitement. At least, that's my non-expert understanding of why some saw blades have these.
@janeblogs324
@janeblogs324 Жыл бұрын
Not only downward pressure but you need to limit the kickback too. You have to be the shock absorber providing steady pressure. When cutting rhs/box/right angle you cut slower on the horizontal surfaces and faster on the verticals. Its all in the surface area/number of teeth engaged at once

I think the most important thing you mentioned was "where to cut". Not enough importance is placed on cutting on the waste side. And on that issue, always cut on the waste side. I was a maths support teacher in TAFE and attended all industry classes so I understood what was needed when helping students with their maths. It was a recurring issue of bits not matching up and poor fits. Thanks John.

A Great video. The number one tool for D.I.Y is measure then cut don't measure the whole length of cuts as you will be short after the first. The other great thing to have is a peg table can make a flat surface easier for construction but are expensive. The most horrible job I have ever done is called lapping. working with a pane of glass with wet sandpaper getting a flat plane on both sides down to a specific thickness sounds like more fun than using the hack saw on cutting old bolts from convenor belt with cleats. great work as always.

Hi John. Thanks for all the good information provided in your videos. Having watched this video re the Vevor Cold Saw and decided to buy one. Upon arrival of the saw I put it to work and cut 16 lengths of 35 shs 2mm wall thickness. It worked well however when cleaning the saw i found the blade suffered significant damage. Those 16 cuts resulted in 4 teeth tips being broken. I understand the saw is value for money and it is all dependant on the skill of the operator however it is a bit disappointing. I will continue using the blade and hopefully finish the project. I thought sharing my experience was important. Again thanks for sharing you knowledge via the videos. Regards Bryan

I have owned my Hitachi drop saw for about 25 years. It pays to get a good quality tool. I would also recommend a 100 mm and a high power 125 mm angle grinder. A die grinder comes in handy at times as well. If you are going to get a bench grinder an Abbot and Ashby 8 inch one is an excellent, durable choice. In all honesty it is not possible to have too many metal grinding tools. What home workshop is complete without a mig/tig/stick welder as well? In my experience it is impossible for a bloke to self actualise without metal fabrication tools. It just can’t be done.

Great video John. How do you think this saw would go in a fabrication workshop? Even as a plan B to that Hare and Forbes saw we have. The two other hot tips I would suggest is... Don't mix and match you cutting discs. As in, don't ever use your worn down hot saw blade on your angle grinder. They are rated at different RPM and may ( and I've seen it) explode and really fuck up the user of the grinder. (The guy in the drafting office was talking the disc home to use. Found it out the hard way) The next tip. In regards to the cutting list. Cut the longer lengths first just in case you fuck up your measurements. It's easier to cut a smaller cut out of a long cut length than joining smaller lengths together. Keep up the great content.

The swarf off those saws are a pain as if it not ALL picked up it will cut and also hook into your bare feet and take weeks to rust away in the grass. This is Australia we like bare feet. With a grinding disk the filings off it are hardly any chance of cutting your feet. They just make little nicks or stick in 1 mm. Also they rust away in the yard in 2 or 3 days. As for your V block do not put the damn thing where you did. It is to be the other side of the square tube closest to the threaded clamp so the tube that is being cut in in the correct position for the saw. There is a reason the STOP is in that position. As for the swarf stick well more like $80 or more. Just throw a strong magnet in a piece of cloth. Worked fine for 40 years so far.

For light duty work, small material sizes and for someone who doesn't have the space, I do like some of those compact cut-off tools. I have a Ryobi one. DeWalt has one that looks pretty nice with that dust shroud. It feels way better than making similar cuts with an angle grinder. It's no match for something like a proper benchtop cut-off saw, but might work better for someone with limited space and only needing to do light-duty and/or occasional work. Good timing though. I'm moving into a bigger space soon, so maybe I'll have to look into one of these. It's a pity you don't have an affiliate link that works over here in Canuckistan as I'd gladly give you the commission if you did. Thanks for the content.

I have been using one for nearly 20 years now as well as a band saw and I always use the circular saw when I need very accurate cuts as whatever you do there is always a little wander out with a bandsaw, for super accurate cuts a cold saw is best but it takes longer the saw is more expensive and so are the blades, of course you can get the cold saw blades resharpened and even new teeth fitted but there are now some companies around that will fit new teeth onto a tungsten carbide saw. I will say that if you want to cut stainless or thin wall tube a friction saw is a better bet.

Just to warn people, cold cut saws with these kind of blades, bit of a different animal to the old style abrasive wheel monsters so you can't just go buy a 14" saw and fit it up to an abrasive drop saw. It'll choke on them, lot more torques needed to run them. Personally I'm still a fan of the whole spin-off cottage industry of angle grinder accessories, you can get belt grinder attachments, circular saws, wood rooter-router discs and even little chainsaws with none of that real safety bullshit you get on actual tools.

I’ve read some people’s comments on channels when someone is using or reviewing one of these saws. All too many times some wise guy comes in and thinks he’s a genius. So he tells people to use a carbide blade on a friction saw. It’s the same size, right? It cuts so much faster. After all, don’t believe the max speed rating on the side of the carbide blade, because the manufacturers are lying to us so that they can sell more expensive saws. There’s so much brilliance out there. One thing about these saws that can be a problem. If the back fence is loose, or on some saws, flimsy, when you tighten the vise, it will bend backwards slightly. That doesn’t matter on a 90 degree cut. But when cutting angles, it does and the top of a square tube will be longer than the bottom, so the cut won’t be 90 degrees from top to bottom.

Replacement blades for these saws are a rip-off in Australia from most shops. If you shop online you can find some decent options for around $150 but in my experience any blade less than 200 is just a waste of money and even then they might outlast the abrasive disc saws but they are really not cost effective for anything above a basic hobbyist. My last fabrication job had this type of saw gathering dust with a fucked blade. Each job involved about 12Tonnes of steel. Mostly cut to size but about 1/3rd was all cut manually. Keep us updated on how this lasts.

I was wondering what the blades cost. Not surprised its half the price of the saw. My old abrasive saw is good enough for the small amount I do and it was free.

Yeah a bandsaw is better, blades are cheaper and last longer

I have a 305mm Bosch version of this saw and when it works it's great but in Australia these saws are an awkward compromise. They are faster than a bandsaw, faster and cleaner than abrasives and cheaper than a Brobo. They are also way more expensive to run than any of the other options. Water cooled cold cut saws are way more expensive but the blades last about 5-10 times longer and can be sharpened whereas the carbide tipped bladed are basically throw away. I've heard it's possible to sharpen them but every specialist I've spoken to who sharpens blades won't touch them. If you need a fast, accurate and productive tool water cooled saws are worth the money. If you're cost sensitive a bandsaw probably gives bang for the buck whilst maintaining similar precision. I hate abrasive chop saws personally and would rather just use the ol 5inch. These dry cold cut saws are in an awkward niche for prosumers who can't justify the cost of a brobo like saw but won't use it enough to be affected by replacement blades costs. To be fair to John that is the exact niche he targets but as someone with one of these types of saw who works in the industry I'm underwhelmed with it's performance. Also for whatever reason, cutting galvanised material seems to halve the life or more. I got about 80 cuts out of Diablo Steel demon blade and it only dulled a bit. I did one project with 2mm wall 50X50 mild steel and after about 10 cuts the blade wanted to explode it was so dull so I had to cut the rest by hand with a grinder. One issue I have is that these saws are not in my view safer than a grinder. Cutoff wheels aren't the worst thing to hit you. I've had discs blow up in my face literally, take chunks out of me etc but as long as you have eye protection you need to be really reckless or unlucky for a cutting disc to seriously injure you. Chop saws are more controlled and controllable but if and when things go wrong they can go very wrong. Especially with a dulling blade. If the clamp comes loose and the blade chatters as it will do long before it's warn out, these saws are prone to throwing that piece of steel at you which is way scarier than a cutting wheel exploding.

If you are cutting angle, don't clamp it as John suggests. Use an off cut of square tube in the vice a bit bigger than the angle. This holds it secure. If you do it as John suggests, the blade can grab the angle and break it free from the vice, as it did to me. Ruined a blade and scared the shit out of me.

A bandsaw is safer, especially if you're cutting up stainless. I use blade saws on non ferrous metals only.

It'll cut aluminum fine but aluminum is so soft a dropsaw made for wood will cut it no problem if your careful how fast you feed it.. I use carbide tipped saw blades made for cutting wood in a milling machine for cutting aluminum

A human has never cut anything. Humans just place tools to material or material to tool at the right spot at the right time.
