EZARC3pcs Oscillating Tool Blades Carbide Multitool Saw Blades for Hard Material, Hardened Metal, Nails, Bolts and Screws, 3-Pack

I did not stumble on these. They were a choice made after extensive reading up on what I needed to cut through some stubborn hardened nails.I was trying to remove the vertical frame of a garden fence panel that was nailed to the main posts - and to do so carefully as I needed to repair a section of it and put it back. I tried prising with all sorts of tools and angles to try and get enough purchase with a claw hammer so I could pull the nails out - no joy! Any harder and I was simply going to split the wood. The nails didn't budge at all.I decided to bring out the big guns in the form of my Milwaukee Cordless 18V oscillating Multi-tool with a view to simply cut through the nails through the joint between the frame and the post. I fitted my Smart brand plunge cutting blade for metal and went for it. In no time at all, the blade was completely blunted and the nail was still intact with little more than a scratch.I was very confident my Oscillating Multi-tool was more than capable so focus was on the blade. I did some online reading and quickly came to the conclusion I needed some Carbide tipped blades for hardened nails. Further review of comparisons of various blades on Youtube convinced me EZARC was the way to go here and the 3 pack pricing made this decision a no brainer. Availability on Prime was simply the icing on the cake.And so the moment of truth. I got my blades on the due date but somewhat late afternoon/early evening so out of regard for my neighbours postponed my rematch with the fence until the next day.Judgment day, and out came the Multi-tool once more, new blade fitted, and I stepped outside to face my foe.We are talking roughly 6 seconds to cut through the first nail - and that was me being cautious, expecting the same blunting I saw with my Smart brand blades. It was same again for the second and the third nail. I checked the blade after each on of these cuts and it was as if I hadn't done anything! No blunting observed! I turned to the other post and was done in a matter of seconds. Within 5 minutes of my stepping out the door, I had the fence panel flat on the ground ready for the repair work to begin.I was so very impressed with these blades that I decided to share this review on Amazon pretty much straight away! Indeed, I am only part way through the repairs as I write but that is for other reasons.Summary? Sure:Pros:Sharp, heavy duty, cut through hardened nails easily, well priced, well reviewed brandCons:NoneVerdict:If these sound like what you are looking for, they probably ARE what you are looking for. No regrets to be had here; you're onto a winner! A+++

These blades are fantastic, I use them for cutting nails that hold corrugated tin on ,some nails are about 6 to 8mm thick and it's no problem for them

These blades cut okay but don’t last too long if cutting things like hardened screws. I thought that 3 blades for the price was good value and they do do what they are intended for

Angle grinder with cutting discs will always be much faster. But when you are limited to confined spaces, multi tool works great. This blade worked well for 4x M12 carriages bolts. Ensure that you do not overheat the blade. Work in increments. Going very fast will dull the blade teeth. Work in small bursts, giving enough time for the surfaces to cool down. I have only used one blade and with all teeth still intact

Though I'd be buying good quality given £25 for 3 blades. Eventually cut through one old very rusty screw and first blade finished.

They dull a lot quicker than I was hoping they would

These arrived the same day - four hours from ordering, in fact. Which is brilliant.Used one of them to cut through steel bolts that had rusted and seized and they worked well.Don’t even think of using general purpose metal / wood blades for this type of job.Expensive but they did the job.

These are far more durable than any 'wood/metal' cutting blades available in builders merchants / Screwfix etc. It's quite a fine tooth so set speed to medium, find the pressure 'sweet spot' and it'll cut faster and last longer than whacking it on full speed which just generates lots of heat. I've cut dozens of nails and a few10mm coach bolts with one blade while dismantling an old stable and it's still going strong.
