    Customer photo review of EZARC Gen 4 Obsidian Carbide Oscillating Saw Blades for Hard Metal, Nails, Bolts, Screws

    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!

    Customer photo review of EZARC Gen 4 Obsidian Carbide Oscillating Saw Blades for Hard Metal, Nails, Bolts, Screws

    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.

    Customer photo review of EZARC Gen 4 Obsidian Carbide Oscillating Saw Blades for Hard Metal, Nails, Bolts, Screws

    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.

    Customer photo review of EZARC Gen 4 Obsidian Carbide Oscillating Saw Blades for Hard Metal, Nails, Bolts, Screws

    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.

    Customer photo review of EZARC Gen 4 Obsidian Carbide Oscillating Saw Blades for Hard Metal, Nails, Bolts, Screws

    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.

    Customer photo review of EZARC Gen 4 Obsidian Carbide Oscillating Saw Blades for Hard Metal, Nails, Bolts, Screws

    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.

    We are a service and repair plumbing company that does a good amount of retrofit and remodeling in older homes. We often have to cut through nail embedded lumber, and cut through obsolete steel piping. These blades have out performed any other brand that we've used, ever. Great product. Looking forward to purchasing your other offerings.

    Quality fantastic, I use a cabled Worx Multitool with ezarc blades cuts nails like the were butter and fast with little or no sign of blade wear as long as you move blade from side to side not only using centre of to cut them. They are everything I expect from the EZARC brand. DO NOT SETTLE FOR ANYTHING LESS (buy cheap buy at least twice or even more 👏👏👏👏 And support team are great George from Glasgow

    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.

    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.
