    I just got a corded Black & Decker 1/2" drive impact wrench.
    It wont budge the blade bolt.
    I dont see in the manual how many ft/lbs i've got
    I've never handled one before, but this one seems a bit...weak?

    I dont want to do this manually.

    I guess I simply need a bigger / stronger wrench?

    I'm open for suggestions.

    invest in an air compressor and nice air impact wrench for the shop/garage. a compressor is a great tool to have around too

    Dewalt has an electric and a cordless (battery) impact wrench that will work with no problems. The real problem here is that B&D is very poor quality. Even though Dewalt is make by B&D, Dewalt is their commercial line. What you are trying to use is a homeowner tool and it's just not powerful enough.

    Bring it over, my IR Thundergun will get them out :D If a compressor and good air impact is out of the question, you need to move on to a better cordless.

    Something I always do also is put some anti-seize on the bolts before tightening them back up. I use that stuff on everthing I swear by it, works great. Comes in a really small tube but you dont need much.

    The Black and Decker electric impacts normally put out around 240 ft. lbs of torque. When you do get these seriously over-torqued blade bolts loose can I suggest that you use a torque wrench to reinstall them as per manufacturers specs? It really makes things a lot easier.

    i think you better check your source of info again, dont mean to flame but i seriously doubt a cordless gun puts out more power then an air gun.
    besides most cordless guns are rated in INCH pounds.
