Bosch Professional 5x Jigsaw Blade T 118 A Basic for Metal (for Steel sheets, Accessories Jigsaw)

Product Information

Set up your workspace. Use a somewhat high but comfortable working surface. You don’t want to be bent over a short painter’s bench to do this project. If indoors, make sure you have a work light or strong headlamp to illuminate your project while cutting. Move other scraps or project pieces away from your cutting area, and make sure the floor beneath you is clear of cords or tripping hazards.

Wear appropriate PPE, this should include eye and ear protection and good quality gloves. The cut off metal will fall, it is prudent to wear sturdy, reinforced toe work shoes or boots.

Tungsten carbide, which is produced by sintering tungsten and carbon atoms, is a much harder material than steel. A tungsten carbide jigsaw blade is made of a steel blade with tungsten carbide grits on the cutting edge. The hard carbide gits are bonded to a steel shaft by brazing, and usually, the blade has grit like sandpaper but has no cutting teeth that are found on HSS or Bimetal blades. This makes a nice smooth cut on the hardest of materials, but also makes these blades expensive. Working with a jigsaw on metal certainly involves some risk, so here are a few ways to be sure your project is successful and without any “ouch!” Move slowly, letting the machine dictate the pace. Forcing the saw to go faster will only degrade your blades and tool motor faster.

Securely clamp the workpiece to the work bench. If there will not be sufficient depth clearance for the blade, the metal can be placed on rails and then clamped to ensure blade clearance. Some metalworkers ‘sandwich’ the metal sheet between two thin sheets of wood to add support while cutting- this technique will take longer but will help minimise distortion on soft or thin metal.Like most saws, jigsaws can also cut through other common building materials, including metal, with the right blade. Use a bi-metal blade with 21-24 TPI on mild steel and softer metals such as aluminum, and use a carbide grit blade on tough alloy steels for best results. How do you cut metal straight with a jigsaw? If you are cutting a straight line, consider using a fence or other straight edge (spare 2×4 even) to guide your jigsaw along. Jigsaws are excellent at precise, detailed cuts, but this also means that a small departure from your guideline will be more obvious from a tiny jigsaw blade than with a larger circular saw blade.
