Our large and small rotaries we do not recommend for metal.  However, if you use them on aluminium, lubricate the tool first, with either WD40 oil or chalk.  This will help to stop them clogging

The Holesaws, Reciprocating, Jigsaw, Hacksaw & Rodsaw blades are more efficient on the hardest of materials i.e. Cast Iron, Steel, fibre reinforced plastics etc
