Aluminum *The blade should be tensioned correctly .
*Since you have two options for each thickness range, use a finaer pitch (more teeth per inch) for thinner sections and coarser pitches (fewer teeth per inch) for thick sections. ** For materials with width higher than 3", decrease at least 20% of cutting rates.
