Dremel MM485B 3-Pack Carbide Oscillating Tool Blade Kit, Flush Cut Blades Ideal for Cutting Wood and Metal - Universal Quick- Fit System Fits Bosch, Makita, Milwaukee, and Rockwell, Black

I use these fairly often with different projects, especially cutting nails and thin metal. I've compared Dremel to other carbide oscillating tool blades and these are plainly better at holding their edge. I use a DeWalt tool and my trick is to cut the ears back a bit on the opening so it fits without an adaptor; these blades are a much better value than the DeWalt so for me it's worth a minute of time to fit these and save some money. Note if you want to cut wood, the Japanese-style teeth blades are the best, but for non-wood cutting these cannot be beat. I'm leaving this review today because I'm buying them again, it's been few years the 3 have lasted for me.

I turn to these blades and my oscillating saw regularly at work, and like all oscillating blades one must take it slowly and do not push the blade or it will overheat and go blunt very quickly. Also another tip is to keep the blade moving and not let one area of the teeth do all the cutting.When used correctly these blades will cut most metals, including cast iron, and can last a long time if cared for. As mentioned, it is important to let the saw do the work and not push them. Note also that they are not really suitable for tile or grout, and one should use the specific carbide granule grinder tile/grout blade for tile work.These carbide tipped saw blades work far better and last far longer than the normal Bi-metal blades so their extra cost is worthwhile. I use nothing else in my oscillating saws at work for wood, plastic, metal nails and screws.--------------------EDIT: 3/25/2015 - I just finished replacing several 2x6 deck boards using one of these blades to cut 25 or more HDG 12d nails. The blade is still sharp. My last blade lasted for over 1 month of continuous use. I just took it slow and didn't let the blade heat up.--------------------Edit: 12/4/2015 - After using the Bosh brand of Carbide toothed blades for the last couple of months, I have found that these Dremel blades seem to be slightly more durable than the Bosh ones. The Dremel blades are 30% cheaper. So I am moving back to using these Dremel blades full time. Excellent value for your oscillating saw.

Yeah I watched the Project Farm video and I tried EZARC blades and a few other brands and none of them lasted as long or cut as fast as the Dremel. The flaw in his video comparison is that you cannot just let the blade go through one screw straight into the next one without it cooling down. The blade will just get red hot at the tips and start to melt. If it was a race to see which blade would take the longest to melt then the Ezrac beat out the Dremel on Drywall screws, but who would do that on a real job?Anyway this is just my experience working with the Dremel Multi Max Tool on a few dozen projects.The Dremel blade cut through wood very well while the EZARC blades do not. Both blades cut through metal very well but I give the Dremel an edge mainly because it seemed to last longer in real world usage and it does not require a stupid adapter to be put in place to use it. That adapter stuff when using third party blades with Dremel is annoying and slows down my work flow. If the third party Blades were better I would put up with it, but they are inferior to Dremels blades so it's a waste of time.My only gripe with the Dremel blade is that I think they could make a better blade if they wanted to. They have been milking the M845B for years because no one else has pushed the envelope and made a vastly superior blade to compete with them on quality or one of equal quality for a significantly lower price.

These carbide oscillating blades are strong, reliable and they make quick work of tough projects where you need to remove old nails, screws and wood. I'm in the process of completely repairing a rotted subfloor that was installed over 50 years ago. Dismantling the old flooring and removing rusty nails has been a lot of work. I couldn't imagine trying to do all of this without my oscillating tool. These blades cut through everything very quickly.

This ended up working great, I had to cut some toilet bolts and a hack saw was just not going to work as there is not a lot of room and so bought this hoping it would work as expected and it was awesome, but right through the bolts as I had 2 toilets to replace, and the bolts were just not coming off. Thank you, great product.

These carbide blades work very well on so many different materials. I am very happy with how long a blade lasts. I have used 1 to cut many pieces of drywall, plasterboard, wood trim, nails, you name it & I am still on the 1st blade.Perfect for cutting outlet holes in drywall for retrofitting electrical to get a clean cut & not do dull.I won't get the benefit of 3 blades, I put them in my multi tool bag & found that one of then broke half the blade carbide teeth tip off. I was sad about that as they are not cheap. I tossed that blade as it was useless, but the blade life of the others is excellent. Carbide is a very hard, but brittle material so I guess it happens.....I would not try to use it for cutting much wood, as the blade pitch & tooth profile is not ideal for this, but if you need to cut some wood, or a nail holding an electrical box inside a wall, or anything similar, they are perfect. Pure wood cutting, go & get a proper dedicated wood blade, it would be a better choice.Use the right tool for each job!Disclaimer: No one has ever given me anything for free off Amazon, as I am apparently neither: Funny enough, verbose enough, factual enough, post enough pictures of 'it' in action or I simply don't buy enough stuff every year to warrant anyone wanting to try to get my opinion. So basically what you get is the unadulterated truth as I see it :-)
