Using your Bosch T318B metal blades is straightforward. First, make sure the blade is properly installed in your jig saw. These blades are suitable for most major brand jig saws, thanks to their T - shank design. When you're ready to cut, whether it's sheet metal, pipes, or profiles, remember to use a cooling agent like cutting oil, turpentine, or a mixture of turpentine and petroleum oil. This will help keep the blade cool and extend its lifespan. These blades work best on medium - thin metals between 5/64' and 5/16' and pipes and profiles with diameters from 5/64' to 3 - 1/8'. For maintenance, after each use, clean the blade with a soft cloth to remove any metal shavings. Store the blades in a dry place to prevent rusting. And always follow the safety instructions of your jig saw when using these blades.
