HASH(0x9e5077a4) out of 5 stars Good blade, not so good price Dec 26 2009
By Remodeling in SoCal - Published on
These blades, like many others with these type of tools, are way overpriced, especially at amazon. I like to buy here but this is one item that should be no more than $25, even that is too much. You can find in most B&M home centers , $25 is as an everyday price. The BIM blades are the ones to buy as the bi-metal is much better at cutting over time than the HSS. The Bosch specific blades work much better, as the adapter doe not hold well and will slip over time on other blade manuf. types. Because of the price of blades, many applications are best done with other saws. I suggest you use this type of tool only when you have no other choice for cutting unless you like spending a lot of money on replacement blades.

HASH(0x9be90894) out of 5 stars Almost Fein-Quality Blade April 30 2013
By Michael DelModesto - Published on
Over the last 5 years I've used several brands of multi cutting oscillating tools and blades. The comparisons of the tools are covered in my reviews of those tools but I've neglected the multitude of blades. In the "fan-style" category this Bosch has been the best I've used. The flat Dremel blade is good on drywall w/ smaller, less powerful "O-saws" and only when a flush cut isn't required but fails to professionally perform on woods or when on the more powerful tools and that's understandable. I've gone through 2 of these, working w/ the third and will buy it again when that one goes. My good friend & coworker has the Fein 250Q and Fein blades which are both probably the best around. I have an M12 multi (w/ XC battery), Bosch 12v Multi-X and a 3 amp Ridgid JobMax, to which Bosch blades seem better suited than Dremel or Fein blades (Dremel blades feel too light and Fein are more heavy duty). The teeth have remained sharp and intact despite the occasional striking of stone, steel and the hardened nails used in older construction. The prices here are better than at my local BORG or BigBluBox stores.

HASH(0x9c0def9c) out of 5 stars The best Bosch metal blade I've used - so far. Sept. 21 2012
By Garrett Blakey - Published on
This blade was included with the Bosch kit I purchased on Amazon. I used it to cut through the metal frames of my old (circa 1960) basement windows so I could remove them easier. This blade cut through the metal relatively quickly. I was able to cut through the jamb and sill on seven windows before the blade became unusable due to too many missing teeth. I think it could have lasted a little longer had I done a better job with the first few windows and not prematurely ruined some of the teeth as I was perfecting my technique. I also purchased a Bosch OSC212TC Titanium Circular Saw Blade thinking it would do a better job than the this OSC312F. It didn't. I wasn't getting anywhere with this new "metal" blade and switched back to the OSC312F. Missing teeth and all, it was like a hot knife through butter compared to the OSC212TC. Even though this OSC312F says "wood / metal" it did a much better job cutting metal than the OSC212TC which says "metal" only. So in my experience, this OSC312F is by far the better of the two Bosch metal blades I've tried (although I haven't tried the metal plunge blade yet). I'll be ordering two more of these for future use.

HASH(0x9c95a684) out of 5 stars It was the only tool I could find to do the job. July 25 2011
By handyhusband - Published on
While installing hardwood flooring I was surprised to find the baseboards in some rooms glued on. I could not pull them without destroying the drywall beneath. I cut around the whole room to prep for the flooring. While not a quick process, it did work. I had one of these blades come with by bosch multitool and I used it to cut the baseboards and the nails holding down the tack strips from the carpet. It worked fine until I cut the nails.

HASH(0x9c2e0564) out of 5 stars Excellant blade but has short life Sept. 21 2009
By G. Robinson - Published on
Verified Purchase
Useful for cutting dry wall, green board, plastic liner in showers, nails, that nasty consumer hostile hard plastic packaging, and the verry crusty French stile bread. (Not to mention wood.) I would pay 2 to 3x more for a harder version that lasted longer and would cut ceramics or glass.

Overall and excellent blade.
