I've been using wood and metal fine tooth blades for my multi tool lately. Cutting in new work boxes in old horsehair plaster and wood lath. I like tracing the box out and the fine teeth cuts a clean outline. It looses sharpness in a short time I'm sure from the plaster. I read that some folks just buy a big multi pack and switch them out as needed. I'd pay for a durable product. So I'm looking to see what you are using and any direction if different brands are better than others. I believe insaw a carbide one for a bit more jingle, but if it lasts a lot longer I'd try one out. These are all smoked...
Last one I bought was titanium coated....it's a little better than the regular ones, but not enough to be a game changer. I think if you want long lasting you are probably going to have to go carbide, especially if there is any chance of hitting anything other than clean wood.
We used multiple brands, and the name brand blades didn't seem to last much longer (if at all) than the cheap generic brands. The blades my Fein saw came with were probably about the best, but replacements are pricey. I would figure in new blades for each job and have it as part of the quote. If its for your own stuff, I'd buy a cheap priced generic brand.
That's how it goes at my place for razor blades for my utility knives. I know I have a bunch, and even know what drawer they are in. Dang, only have 1 left in the pack so I pick up more. Open the drawer to put the new pack away, and suddenly I see the previous 2-3 packs I bought - all unopened
I was thinking about this thread when I saw this yesterday. Pretty interesting channel he has testing different products.
This guy does admirable work. I saw this one pop up on his channel and thought of this post. He did a great video on vehicle undercoating which I referenced in another post here. Unfortunately, the blades that came out on top in his testing aren't available at my local big box stores. Bosch did rank highly among those sold there though which reflects my own first-hand experience.
The problem with that video is it isn’t exactly how I would cut nails. I would move the blade around to help keep the heat down, maybe use some oil. I think some of those blades would be great if you used them right.
I think his tests are designed to simulate worst case scenarios. After watching several of his videos, he does a fair and thorough comparison.
I just watched another of his tests on the holding strength of fasteners including different types of nails and screws. It blows away the adage that I've often heard from old-timers and others that nails hold just as well as screws. It also confirms my personal difficult experiences with pulling ring shank and galvanized nails.
I also hear the one about Sheetrock screws having no shear strength. They did better in the tests than I’d of thought, but all the screws appeared much more brittle than nails in the back and forth test.
