The real trick is to lube and to keep the shoe on the work.
This means push against the work as it saws. Using the correct pitch
blade is important - e.g. the 3 tooth in the metal at a time rule is
kept here if possible.



For most sawzall type metal cutting you only dull the first inch of
teeth from the saw "shoe"
2 ways to get more life from the blade

1 make a shoe extension that extends the shoe past the dull portion
and screws to the existing shoe.

2 grind and snap the dull portion away and grind a new tab on the
blade for the saw to hold

and of course ANY oil when cutting is better than none.
