Dear handyman. Thank you for the review, I am also a Lennox Diamond user, and I must say that to make the review fair I would suggest to use an AC powered angle grinder instead, as the battery powered ones reduces in speed as the battery pack is being drained. I use Bosch 4inch 18Volt angle grinder, and I agree that using the Lennox does indeed cut slightly slower and tends to grab. However, the benefits of safety and cost savings per cut out weighs it's drawbacks. I also notice that Lennox produces less sparks and the metal debris are not contaminated with abrasive powder. Furthermore as I am working outdoors from one site to another, keeping the Lennox blade attached to the angle grinder in a tool bag will not cause the blade to break.. unlike the 1.2 mm thick abrasive wheel that is wasted even when I accidentally rest it at an angle. In Malaysia where I am from, an average abrasive disc 1.2mm cost RM1.2 per piece (£0.22) Whereas Lennox 4inch will cost an average of RM45 per piece (£7.34) The price difference is huge however it last so much longer without sacrificing cut depth
Excellent unbiased and objective review, just how it should be. I've been getting tired of so many other DIY channels doing promo's and paid reviews of all the stuff they get sent for free, ughh!
Thanks Peter, I get sent stuff for free (sometimes) But if it's shite it goes in the bin and no video is made. I got sent a Bluetooth battery once (£150), decent make of power tool, but Bluetooth on a battery is a really, really crap idea! Thanks for the comment 👍🏼
Yes, bluetooth batteries sounds about as silly as solar roadways! Showing free products relevant to the channel with no strings attached on what you say, and declared as such, are perfectly acceptable of course! :)
Thanks for a super video. I have both type disc for my Dremel and for my 4 1/2" grinders and I think there are use cases for both. I'm just glad that we have some choices. Thanks for sharing 😊
thanks for another great video. The filth that abrasive discs produce is the biggest issue to me, had never really considered a diamond disc. Will definitely buy one now!
I have to wonder about the 30x lifespan. My experience with diamond products is with honing cards for wood turning tools. These do not last long and this is with just honing so very little heat produced. The matrix which holds the diamond particles to the base steel plate does not hold the particles well. In the Lennox blade the heat it produces could result in losing the diamonds long before the rated lifespan. In the video the pieces of angle were melting at the end of the cut. Dave.
Pretty sure that the state of California has cancer warnings on roasted coffee too, so don't think I'd worry about that warning too much, as long as you use PPE
I've used abrasive slitting discs for years and never had one blow up. Just choose your cutting line and keep the thing straight, and don't lean on it too hard. It's user error having discs blow up. Those diamond discs are good for masonry but hopeless for metal, and they don't last anything like they're claimed to last either.
Abrasive discs don't normally get hot- they just produce a lot of sparks. I didn't measure the temperature of either of them, I'm afraid. Thanks for the comment 👍
I have used my diamond cutting disc about a dozen times and is is brilliant cuts fantastic with no problems all come down to the way it is used you start putting too much pressure on the grinder it will ruin it
I have never used one, but have heard that they can be bad for kickback. A company keeps offering me a wood cutting blade for a grinder, but I don't want to show something on the channel, that might cause injury to someone! Thanks for the comment 👍
@@ultimatehandyman i just bought one from harbour freight but I'm very skeptical on using it now!! I'm want to remove a small tree trunk but I don't want to die
I recently bought the Parkside 20v cordless grinder from Lidl along with a pack of discs similar to that Lenox. For the money I can't fault either, although I'm an infrequent user. I feel more confident using a metal disc as they are a lot safer.. Personally I'd always choose safety over speed. Good video👍🏻
Disk breaking is 99% of the time users fault. The only time disc shatters is when it gets blocked between 2 sides of material you are cutting.There are discs out there that are flexible and can whitstand amazing angles. Learn how to keep angle grinder straight,use proper disc for job aka dont use stone disc to cut metal and you wont have to worry about breaking a disc.Watch for maximum rpm speeds,dont push too hard into material,since angle grinder cuts by friction ,if you push harder you wont go faster,just wear disc faster. Dont buy cheap crap made in china.,some of them may be good but mostly they are crap(i bought dremel ones that couldnt cut anything ). I have discs that are 30-40 years old for my cut off saw and they work just fine.Keep them dry and you wont have any problems. Diamond wheels will worn out ,now how fast that is the question,they probably cost 10x more which is for me a big no for a consumable item that does same thing but costs way much more.
i been a panel beater since 86' i use the 1 mm slitters and thicker for sheet steel and taxi chassis, i personally havent had one explode, maybe because i dont push hard on them cos then yu just burn up the discs, only time i have broken any is removing them if they locked up during a cut extra tight.
Few very important testing criteria we've tested for: 1. Material vs abrasive: Diamond = 100% carbon. Using diamond on metal, you get carbon transfer. You increase the carbon content of whatever you are cutting = bad bad bad! If you know anything about metal you would know that a higher carbon content means a harder and more brittle steel. Not recommended if you are complying with safety standards. 2. Heat: Diamonds can get blunt. The discs might advertise many cuts in its lifetime, but after only a few cuts, the diamonds blunt and you are actually just melting through the material, not cutting anyone. You would ask why this is an issue... the next point explains why. Lastly on this point, do not use it on stainless steel. Heat distortion and cross-contamination will break the chrome bond that makes stainless steel and cause rust. Big no-no! 3. Machine wear: You would know that brushes and armatures are expensive. You are cutting slower because you have such high drag and friction cutting metal with metal (coated with diamond). Hard vs hard is not great. This increased friction puts enormous amounts of strain on your machine. If you do 20 to 30 cuts in a row with a 700-900W machine, you'll start smelling something burning...maybe some smoke. Its not the paint... its your machines carbon brushes packing up. Not the greatest if you can do 400 cuts with a disc but you need to buy 2 or 3 machines to do them. Do these tests and find out for yourself. Happy testing guys!
There's special abrasive discs for cutting Ali,easy available in the UK,abrasive wont shatter if used correctly,remember its the tool that does the work not the operator
abrasive disc wins it a few times over in that test, whats the reason you shouldnt cut copper/ ally with an abrasive disc? for clogging or the air borne particles from copper/ally? if you using the discs outside california do they still cause cancer.................:P
If I remember rightly, copper dust is toxic, aluminium dust can be explosive. Also metal cutting discs are made from aluminium oxide, so if you must cut aluminium using an abrasive disc, you should use a masonry disc, as they contain silicon carbide. (with the correct PPE) Thanks for the comment
I really enjoy watching your videos - very informative. Have you thought about making some on motorbike maintenance - brake fluid change, oil and filter changes etc? I think your great instructional technique in this area would work really well. Just a thought. Thanks for all you do.
I bought one of these and I got about 8 inches into a sheet of 3/16 aluminum plate before it just stopped cutting. I finished the cut with an old school metal cutting blade that cut faster and further with little wear. So much for "long lasting". I bought the blade today, and I'm returning it today. I don't recommend anyone purchase one of these unless you're just interested in wasting your time and money.
Thanks for the info, I think having watched that that I'd use the diamond disc on roofing iron and other thin metal and the grinding discs for anything more substantial. I suspect the diamond disc wouldn't cope well with over-heating.
A cordless angle grinder is probably the least fair comparison tool one can use. It is optimized to work with a abrasive disc and gives the Lenox blade a huge disanvantage! Try again with a proper corded grinder.
If these discs are not suited for cordless grinders, it should state that on the packet. Cordless grinders are superb these days ;-) Thanks for the comment 👍
@@ultimatehandyman They are superb in terms of handyness but compared to a corded one they lack power, torque and speed. During your test it stalls several times, that would never happen with a corded one. If you compare the specs of a really really good cordless grinder with a corded one from the same manufacturer you will see my point. Normally the cordless have about half the max rpm and power than the corded one.
Sorry mate you don't know how to use a grinder you do not put that much pressure on Grindr you put just a little bit of pressure and allow the machine to do the work it's the same as using a drill allowed the drill bit cut and the drill to do the work
I just gave mine away last week. The Lenox is, on the surface, a good idea but it just takes too long to cut and causes way too much surface heating. I won't be buying another.
Excellent edited again👍👍. Would you only get cancer in california or could it happen in other states😁😁😁. There are quality cutting disks. Smelt of burning made me chuckle, tea with two sugars was it👍👍👍.
I'm kinda tired of abrasive just shattering all over and having to count my blessings for doing everything else that was in my control and preventing those shards from making me into minced beef. Tbh metal work has a lot of danger there is no doubt or complete elimination of that but diamond seems like the way to go for me. I personally would rather spend an extra minute on a cut than to lose my fingers to those God damn abrasives.
Well, this has been an eye opener, for me at least. There is no doubt that the abrasive wheel/blade is much faster at the job than the diamond, and as time is money, advantage to abrasives. That burning smell or 'brimstone like' smell you get is from the abrasive wheel compounds and I am sure that California will have something to say about that too, and they'd be correct in that. ( But then we all know that the State of California can prove that a glass of water may 'kill' you too ! LOL!) The thickness of the kerf is material lost and also determines the speed at which a given blade will cut, in most cases, so advantage to abrasives again. The shattering of an abrasive wheel is a very real possibility so advantage to the Diamond wheel here. ( This make me cringe every time I see people using grinders with the guard removed, and we see this a lot , don't we?) It's 'funny' but I have never had an issue with dated abrasive wheels/blades as long as they were kept and stored in a dry place. A damp or soaked wheel is discarded immediately in my shop, such as one that may have been left on the floor for some time; if it's on the floor, it's in the garbage! Thanks for this test, I now know what I need to know when buying these in future.
Yes, the abrasive disc was much faster, although if the thin (slitting) abrasive discs had not been developed, I think you’d get a similar result with a normal metal cutting abrasive disc. I’m sure the state of California would have something to say about the smell of the disc in use 😉 Like you say there are a lot of people on UA-cam that use grinders with no guards, wearing Jesus sandals and generally not respecting the machines. I saw one guy using a pair of water pump pliers and mole grips to removed a disk, as he didn’t have a pin wrench! Expiry dates on discs, is probably not that important, but best not to take the chance- especially inexperienced users, who might cause the disc to burst. Thanks for the comment 😉
@@ultimatehandyman I did see a gas powered cut off saw have it's 12" cutting disc/wheel blow up. It went off like a vibrating small hand grenade; the worker did have a guard in place then, he was very lucky that he did!
Diamonds are a bad idea for cutting/ grinding steels, because the carbon in the diamonds wants to diffuse into the steel, wearing down your tool and hardening your workpiece.
You need to practice cutting within the kerf of the blade that is why you kept getting stuck with the Dimond disk and it is the cause of dick explosion you weaken the wall and the thicker outside releases and explodes
BTW, Prop 65 warning means absolutely nothing, look it up
yupe,, Fresh "Clean" air would come with a California prop 65 warning if they could figure out how to make the ink stick... most of the inks would then need a second warning.

Nice review. Thank u, and 2u 2 sir!🙂
Thanks for the comment ;-)
I was disappointed at the performance of the diamond wheel. I would have thought it would've done better. Those are way to slow.
Dear handyman.
Thank you for the review, I am also a Lennox Diamond user, and I must say that to make the review fair I would suggest to use an AC powered angle grinder instead, as the battery powered ones reduces in speed as the battery pack is being drained.
I use Bosch 4inch 18Volt angle grinder, and I agree that using the Lennox does indeed cut slightly slower and tends to grab.
However, the benefits of safety and cost savings per cut out weighs it's drawbacks.
I also notice that Lennox produces less sparks and the metal debris are not contaminated with abrasive powder.
Furthermore as I am working outdoors from one site to another, keeping the Lennox blade attached to the angle grinder in a tool bag will not cause the blade to break.. unlike the 1.2 mm thick abrasive wheel that is wasted even when I accidentally rest it at an angle.
In Malaysia where I am from, an average abrasive disc 1.2mm cost RM1.2 per piece (£0.22)
Whereas Lennox 4inch will cost an average of RM45 per piece (£7.34)
The price difference is huge however it last so much longer without sacrificing cut depth

You should never do testing using a battery power tools. This isn't accurate because of the lack of power sometimes.
