EZARCTitanium Oscillating Multitool Blades Power Cut Saw Blades Fast Cutting for Wood, Metal and Hard Material, 3-Pack

These blades are excellent. They are designed to do what the manufacturer claims they can do IF the blades are used properly. Here are two responses to poor reviews.First, other reviewers apparently think they can cut masonry, cement board or other such products with these blades. These blades are not designed for such materials, and the manufacturer does not claim that the blades will cut these products. Please, stop leaving poor reviews based on your own misuse. Instead, purchase an abrasive blade that claims to cut masonry-like products.Second, other reviewers complain that these blades dull on screws. I understand the confusion, since the description says hard metals. However, these blades can cut nails, not screws. Nails metallic composition is not the same as screws. Framing nails are designed to prevent lateral shearing. Nails typically bend (are more malleable) rather than break. Screws are more brittle. If you hammer a screw over while its in a board, the screw will typically break. Screws are designed to pull things together, not prevent lateral shear. Because of the difference in malleability, blades like these will not cut screws, but they will cut nails fairly easily.

Remodeling can sometimes throw wild curves. Within a vaulted ceiling I had come across sistered (double thick) 2x6 rafter bracing that needed to be trimmed to make clearance for a new skylight.With no room for anything but an oscillating saw this extra long blade provided the depth needed to get through the 3 inch thickness of the bracing.I'm so glad I chose the Rockwell F80... it has an oscillating amount setting for Metal (3. 4 Degrees) or Wood (5 degrees). Using the Metal setting with this extra long blade made it move back-and-forth about the same amount as a short blade on Wood setting. I had good control and was able to cut super deep with ease.This EZARC Long Cut Saw Blade saved the day for me.-BTW- I wouldn't use a wood blade on nails, even if the maker says it's okay. Metal only blades and carbide blades can make it through nails without disappointment.-Learned safety tip: I plastic bagged my oscillating tool before working in the ceiling where I had previously removed fiberglass insulation. I used a 2 gallon food bag (since it was handy) and just poked only the blade through and then (with my mask on) started cutting. The plastic bag kept the motor's fan from blowing fiberglass insulation dust all over me.-Learned safety tip: I really hate working around fiberglass insulation. I HEPA vacuumed (shop vac w/HEPA filter and HEPA bag) the area first and then used Zinsser spray can shellac (stinky but dries in seconds) to mist the area. This will bind some of the remaining dust and also make some loose fibers bulkier. Cheap hair spray like Aqua Net might work too, next time I'm trying that I just didn't have any on hand.

Ive been purchasing these for years , the best all around blade. It is easy to control, cuts through nails, great on pvc. But my last order was different, they are much shorter than prior. Meaning less cut depth and less osolating action.

04/02 Update:So, I've learned a great deal about these blades over the past week.#1. This product turns out to be really awesome if you use them correctly. After several YouTube videos and asking others, I have to share what I have found.#2. Don't force the blades. Lock them in at the highest speed of your tool and let the blade do the work with little pressure and a slight rocking motion. For me, I've found that about the weight of my tool is just about the perfect pressure. Pushing these blades hard in the material you're cutting will produce horrible results and damage your blades completely.#3. The long shaft blades in this set are total "money", they are awesome and work so much better than any short "standard" shaft blade. In my opinion, all of the blades for this tool should be long shaft only.#4. The seller immediately reached out to me about my original review and problems I was having with the blades I got. They want your feedback and they want to help, so that's the icing on the cake for me.#5. I tested what I learned over this weekends demo job. I was able to use one blade through the entire job. It still has teeth and is still going strong. I'm probably not supposed to use just 1 of these blades for metal and wood but I did. I cut through rusty bolts, electrical, hardwood, softwood, drywall screws, aluminum siding, rubber, plastic, you name it. I got more done this weekend than I had the previous 2 weekends and man it felt good. The greatest part was I only had to change my battery on the tool the whole time.Speaking of batteries, these blades do not work well at all on a weak battery, keep it fresh and you'll cut up everything 😉--------Original 1 Star Review:I have to admit I was so looking forward to these blades per the reviews I read. As you can see in the photos, the very first blade out is burned and teeth are gone in one spot. This blade was used on a close set group of 4 Brad nails and the blade only cut 2 of the 4 before the big burn up. Also, this blade did NOT seat well on either my Milwaukee or Dewalt but enough to use it. I wouldn't recommend these for metal or wood as they had trouble going through 1/2" plywood as well.

The cutting edge works great going thru nails and wood but the mounting portion is cheap and every one of the mounts broke before the blade went dull. All others blades I’ve used (name brands) have held up until cutting edge dulls. The only reason it gets three stars versus one is because of the sawblade itself is very durable.
