Many tools are "Case Hardened". This means they were put through a hardening process that makes the surface of the tool very hard and underneath is softer. By grinding the surface off to change it's size you remove the case hardening. Better to buy the right tool in the first place. Snap-On makes an adapter that fits, I don't have the P# right now. You CAN use a piece of square stock bent into an "L" and put a piece of pipe on the end to make it longer if you have to. Some plugs can be VERY stubborn but a long wrench and a hard, fast rap on the wrench gets them loose. It is also bed practice to use a torque wrench as a breaker bar. Good tools are an investment, budget for some on every job if you need to but it is always better (and safer) to use the correct tools.
