BOSCH 1-1/4 Inch OSL114C-3 Starlock Carbide Plunge Cut Blade 3-Pack - Professional Oscillating Multi-Tool Accessory with 3D Fit Interface, 30X Longer Life, Compatible with OIS Tools

Simply amazing! I had doubts that these blades would work as well as Bosch claims. I do not have doubts any more! I was cutting through 3/4" sub floor with thinset mortar and the remains of ceramic tiles on it. All the other blades I used ( bi-metal) got torn up almost immediately like cut six inches and the teeth were worn / broken off. I used one of these carbide Bosch blades and finished the rest of the job and the blade teeth look just as good as when I started. I saw afterwards I had sawed through nails and screws and even some ceramic tile, but it cut so well I never even noticed. There were two nails that got cut longways (as in the nails were split top to bottom so 3/4" of half a nail was left) which was hilarious. In this tough application, these blades are lasting way more than 30X the life a standard bi-metal blade. Cutting speed is about the same as the bi-metal blades (when they are new / sharp) but the cutting speed does not slow down because the teeth never get dull. A little bit expensive, but well worth the money.

These carbide cutters work, period!

In just a few years oscillating tools have become must-have for pro remodelers and other trades. It's no wonder - with the right blade you can cut just about anything, and in tight spots that are impossible with other power tools. But "Right Blade" is easier said than done. Oscillating blades are ridiculously expensive for what they are, and worse yet, most "wood cutting" blades most will be ruined by hitting a single nail or screw. The "bi-metal" blades with a slight hacksaw type tooth are a *little* better - instead of one nail doing them in maybe you'll make through 2 or 3. Point being they're still pretty wimpy. Now enter the Bosch carbide tipped blades. These are BY FAR the longest-lasting oscillating blades I've found. At around $10 each they're still expensive for what they are - but ordering them via Amazon is MUCH less expensive than the same thing at my local big-box. There- 3 blade bi-metal packs are roughly the same price as these. SO... How do they cut ? In "just wood" to be honest there are much faster blades out there. They get the job done, but I wouldn't use these carbide-tipped blades if all I had to cut was clean new wood. The teeth aren't aggressive enough (not much, if any, 'set', so they're +/- mm like cutting wood with a hacksaw blade. BUT - for common chores like cutting the end-nails and sheathing staples in a stud wall ( for instance to replace a twisted stud - cutting the 16# nails first and then back-cutting all the sheathing staples so you can pop out the bad stud without shaking the heck out of the wall - or having to cut an incorrectly sized header out - THESE ARE DA FREAKING BOMB. Instead of being ruined by the first or second cut like EVERY other blade I've ever used... I worked all day today with ONE blade and the teeth are still intact and sharp. I wish I'd found these a year ago - I would have saved myself a few hundred bucks in wasted bi-metal blades. I didn't try cutting sheet metal or heavier stuff like a metal cover plate, but I'm sure they'd work in those materials too.

Only reason these dont get 5 stars is the high price compared to most others. But the Bosch easy change system is great and these blades seem to last longer than most

Great and lasted awhile until I hit concrete

For those wondering, these DO fit Ryobi products! So far these work amazing. MUCH better than the original Ryobi ones that came with my oscillating tool. Can’t speak for logevity yet, but I’m already impressed with the performance in cutting all sorts of woods.

I had an old horse stable that needed to be demolished, but I wanted to reclaim the tongue and groove cedar siding to use in another project. The wood is old and brittle, and the hot dipped nails have been married to the wood for half a century so trying to pry the wood off the structure frame was not giving me the outcome I was looking for. So... I read some reviews on these blades and was assured they would do the job of plunging between the stud and siding and cutting the nails to free my precious aged cedar. I even bought a tool just so I could use these blades. True to their reputation I liberated over 500 board feet with just 5 blades. On average that calculates out to about 230 8d (about 1/8" diameter) nails per blade. I was thrilled with their performance and still have half a box of blades for my next demo project :-)

Make sure these blades will work on your multi tool. Mine will take just about any blade so when I saw these for a really low price on Amazon, I snagged them up. Think it was a sale or something, didn't even need any blades at the time but the price was too good to pass up. Haven't used these blades much (yet) but I have yet to have any issues so far with Bosch blades. Other than price, sometimes. I do like that Bosch offers blades that are a little different than other manufacturers, slightly different shapes and options. Sometimes a bit longer (like the jigsaw blades I needed) and these narrow skinny then opens up for a wider blade tip. Not like the run of the mill Oscillating Multi tool blades. Sure its not always gonna make a huge difference depending on the task, but certainly can be very useful. All in all these seem well made. I haven't put them through the ringer, mild usage so far but all seems good to me

Maybe my expectations are too high but I was surprised that the teeth wore flat on these when cutting a screw.

I have tried 2 of these blades to cut through rusted nails and they only cut 6 each for a price of £19 each. They are very expensive for what they do. Unfortunately because they are star lock fittings you cannot buy cheaper ones from different suppliers as that would be the best route

I am cutting plaster. Not drywall, but real old style plaster that is filled with small stones. Bi-Metal blades worked but the teeth wear off very quickly. The teeth also wear off these Carbide blades but they last a lot longer. They are not lasting 30X as long as claimed on package, but are definitely lasting 3X as longer which makes them lower cost in use than Bi-Metal, and the work goes faster when I don't have to change the blade every 5 minutes. I did try a diamond disk blade in the Multitool but it didn't cut well.

Brilliant product good hard quality last really long cuts through anything worth the money

The Bosch blades are top notch, and outlast all others I have tried. A bit pricey, but all Starlock blades are… I feel these are money well spent.
