Re: 10" brush blade
Never saw a carbide tipped blade, but I do have a steel blade that I have pushed to the limit on more than a few occasions. Went from full rpms to pretty much stopping it dead with too much of a bite(my fault) and didn't warp twist, or break the blade - more concerned about the punishment the motor took.
