@Project Farm
EZARC is your best choice when considering cutting speed and cost performance, maybe there is no better one than it. I recommend it to everyone.
@Mechanically
I'm a contractor and I have tried about every blade out there and these seem to be top shelf. Im not gonna say they are the best but i will definitely be purchasing more.
@medomechanic
Oh, let me tell you about the incredible Diamond Cutting Wheel! This tool defies all expectations and cuts through metal like a hot knife through butter, that’s simply out of this world!
@soyflaco0
This countersink set is a must have in your tool box. It is important if you're a stickler for finishing jobs and want everything to look amazing and beautiful. It is very durable and will last after job.
@brc_framers
This disk is immortal. I've cut so many things its hard to understand how the disk even exists anymore, let alone still cuts things... I will encourage others to buy them.

I really enjoyed the ease and durability of my oscillating blade from Ezarc, it cut through copper and thick brass pipes like butter, I can't wait to try it out on steel nuts and bolts.

Excellent durability , the blade still intact after cutting 4 grade 8 bolts.
Robert L.5/5Verified
I bought six of these blades and I’ve been using the same one for over three weeks now, I’ve used it on Durock metal wood. Everything in the blade just keeps working. It’s amazing.

Decent product and fits on Dewalt and Dremel brands as advertised.
They include an adapter washer for use with the Dremel but I found that while it can be inserted, it's not necessary. Nice that they include it anyway.
The tool lengths are very similar to other brands of blades and a quick test of the blade on some wood gives me the impression that it cuts just as well as others brands. The tooth count seems reasonable, not too fine or coarse and cuts through material without getting jammed or burned. The longer durability is always hard to gauge, if you're cutting nails and metal it will obviously wear out quicker. I like that the metal they used is fairly thick at the tool end, they didn't cheap out.
Good product!

I used these blades on a cheap 2.5A oscillating tool, nothing fancy or overpowered, and I'm actually taken back with how they performed. With a little cutting oil (it doesn't say to use it, but I've done this for years and it's why my blades last forever), I cut through about 16x rusty 3/8'' exhaust manifold bolts while tearing down an engine. That's the kind of job that normally eats blades (or requires torches) and these blades barely noticed, and it was still cutting clean after.
I never really thought of my oscillating tool as a serious metal-cutting tool as it's always been my drywall, sanding, and trim helper. These blades completely change that. They turn a basic oscillating tool into a small but legit beast. If you work on metal even occasionally, these are absolutely worth it. Very happy with them.
Marcus A.5/5Verified
These blades have noticeably increased the versatility of my oscillating multi-tool. They work much like a small metal cut-off saw, which will allow me to slice through bolts and nails without hauling around an extra tool like my Sawzall. That's a big plus. Fewer tools mean less weight to carry and less strain on my back.
The blades feature a titanium aluminum nitride (TiAlN) coating, designed to improve heat resistance and hardness for a longer lifespan. From experience, I know cutting tools last even longer when used with a bit of cutting oil and when given cooling breaks, since heat is the enemy of any blade.
The set includes several adapters for compatibility with oscillating tools from different manufacturers, though mine fit perfectly without one.
For testing, I used one blade to cut into a large bolt head to create a slot for a screwdriver, and it cut in with minimal effort.
Dono3455/5Verified
These are pretty good cutters which actually last a fair bit longer than the regular steel cutting head. I'm using this with my Dewalt oscillating tool and it fits the tool just fine. I'm doing some demo work on door frames and trim which requires me to cut through nails. These carbide cutting blades still had a good cutting head after an entire day of cutting through nails. By comparison, if I were using steel blades, I would have needed to change them at least 5 or 6 times. The carbide blades still had lots of life in them so I am able to continue using them for the next jobs. I am able to see a small bit of wear on the blades but not significant enough to prevent it from cutting. It also looks like the blades are coated with the carbide material, rather than the full cutting head being made of carbide. So once this layer wears away, it will have the wear characteristics of steel. This is not a terrible thing as the steel can be re-sharpened if you have the serration tool so it should give this blade a bit of an extension on life.

While looking for devices to aid with precision cutting, I am very pleased to have discovered these Oscillating Multitool Blades ( see photos ), with a nearly-universal OIS interface, from my inspections and initial confirmed to be compatible with my Mastercraft #054-8251-6 Corded Multi-Crafter Oscillating Tool.
From my observations, I can confirm that the Blades feature; 3 identically sized blades measuring 1-3/8'' (35mm) wide at the business-end with a 2'' (5cm) cutting depth; 'TiAIN' coated industrial carbide teeth with a geometry designed to quickly slice through metal with a long service life;
[ two titanium for metal cutting, four with a curved front edge for easier starting of precise cuts, and four HCS for wood cutting] and three adapters [for specific brands]. I find the blades to be strong, reasonably-durable, very effective, and can recommend.

Works great with my new project

Wow!cut through grade 8 bolt like a deli slicer. Still some life left remaining. Very impressive
Marc5/5Verified
EZARC should pay me for the reviews, but they don't. I've been a fan of their oscillating saw blades for 3 years. These seem to be a little tougher than some of the other ones, and the price point is very good. There's no reason to spend a lot more money on blades.
David W.5/5Verified
I'm an electrician and had a kitchen remodel job with old plaster walls that was destroying my standard oscillating blades. One hole for a single gang old work box was equaling one blade with no teeth left. So I went to the big box HD to find that a carbide blade was very costly & wasn't sure they'd work, so I searched on google & came across these which were priced 3 for the cost of 1 at big orange, so I gave them a try. They worked after multiple uses, including the old plaster, and I'm still on the 1st blade a few months later.
Jerryp23755/5Verified
These things cut through almost anything. Very nice
Richard M.5/5Verified
Great on metal for sure! I've used Metal blades from big box stored and they lasted about 12 seconds before all the teeth were LONG GONE!
I used this on a ball joint on a car as the nut was giving me trouble and and in 30 seconds I was cut through and it still had plenty of teeth!
HIGHLY RECOMMENDED!!
Gary5/5Verified
Used my first one, longest lasting blade I had used so far.
Paul K.5/5Verified
At first I really didn't expect too much, maybe a bit better than other blades. Well needless to say, this blade cut threw 10.5 harder steel bolt. No broken teeth either ! Matter of fact, one blade three cuts. That's impressive.
Kenneth P.5/5Verified
Great product
Adrian P.5/5Verified
The product I purchased I could not be happier with. It is anazing and I have honestly abused the first blade just to prove how good or bad is was. My absolute dissapointment is when I attempted to order more.
The website and pop up offers were too much to take in or even negotiate.
I am quite sure that new or existing customers will look to repeat order and even try some of the other range you offer.
I have tried and tried ( maybe i am a bit thick, many tradesmen are
Lol ) the website / ordering needs drastically simplyfying. Not all users of ypur products are IT experts. Your product is 110% brilliant, your website / ordering / reordering is far far too complicated. I will not be reorderingbor using new products untilll ordering is simplified or somebody explains to me how to make it easier.
Regards a very happy existing user but a very frustrated customer who is finding it impossible to positvely know what I am about to reorder and what I am paying.
Philip B.5/5Verified
I was skeptical if these would do what they advertise these days. But to my surprise, they were awesome! I cut through 20 crown staples, a handful of framing nails and a few pieces of hardi trim with the same blade!
The most impressive part is that there was not 1 tooth damaged or dulled, I recommend these for any Contractor.
Chad S.5/5Verified
I bought these to cut through metal and they did
Terry M.5/5Verified
Very happy with then so far
Joe G.4/5Verified
Super strong blades that last for multiple uses. Heavy duty to cut through plaster.
Scott R.5/5Verified
They look good, I have not use one yet. Order came fast.
Frederick C.5/5Verified
Best blades I’ve used on metal 👍👍
Carl B.5/5Verified
Time will tell
Antonio Z.5/5Verified
best blade yet!
Joseph S.5/5Verified
Great product great buy
Derrck B.5/5Verified
Works well for my home projects. These carbide oscillating blades cut through nails and small screws in tight spots where a grinder or Sawzall is awkward. They feel sturdier than the cheap bi metal blades I used before and they do not dull instantly the moment you hit metal.
Cuts are still not magic fast, but the big win is less frustration and fewer blade swaps. I used light pressure and short bursts to keep heat down and it stayed sharp.
Only thing to flag: check the package right away and confirm you actually received all 3 blades.
Jellyrobot5/5Verified
These things are literal beasts. Cut through 1/2 inch bolts like butter. Best EZARC blade yet.
Mike T.5/5Verified
Good durable blades but package and ad says it comes with 3 blades. Only came with 1 in package. Please send me 2 more blades to make this right. Thank you.
Kreig J.4/5Verified
i used these for some rusty exhaust manifold bolts. tialn coating is no joke, didnt even turn blue from heat.
Gearhead_steve5/5Verified
Good quality. Fits my DeWalt perfectly. A bit pricey but you get what u pay for.
J.r.4/5Verified
I've been using EZARC for 3 years now. The Gen 4 is a massive step up in speed.
Thefixitguy5/5Verified
I picked up these carbide blades because my usual oscillating blades tap out pretty quickly on nails and small bolts, and these are in a completely different league. First test was trimming some old framing nails flush in a tight corner where a grinder would have been awkward. I snapped one of these onto my multi tool, lined it up, and it chewed through several nails in a row without the teeth rounding over or the blade turning blue from heat like my cheaper bi metal blades usually do. The TiAlN style coating and carbide teeth really shine when you are cutting metal on metal, you feel less grabbing and more steady, controlled progress. They are not cheap, but with the extended life compared to standard blades, I am using one blade for jobs where I used to burn through three or four, so the cost feels justified. If you often deal with screws, bolts, or embedded nails, these make the job faster and a lot less frustrating.
Wyldknyght3/5Verified
Takes a bit longer on hardened steel than expected but still better than the cheap bimetal ones from the big box store.
Dusty_workshop3/5Verified
Finally a blade that doesnt dull after 2 cuts.
Builditbetter5/5Verified
This is an excellent pack of oscillating saw blades for hard metal. Works very well to fit in tight spaces and cut through bolts. They are reasonably durable as well and last for multiple jobs.
