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

Product Information

Jigsaw blades have a single row of teeth along one edge of the blade, these are arranged in a small wave pattern from left to right- a blade with 21-24 tpi is recommended for cutting metal and one manufactured with a bi-metal construction will offer the best durability. Drill Start Hole: If you aren’t starting from the edge of the metal, use a drill with a metal-specific pilot bit to create a guide hole in the “waste” side of the piece close to your line. Jigsaws are not suitable for plunge cutting metal, however, a hole can be drilled to feed the blade through and then the cut can be continued in the usual way. Jigsaws have good manoeuvrability which makes them ideal to cut quite intricate shapes;, on tight curves it is advisable to make relief cuts to reduce the risk of the blade binding, however, this will only be possible if the cut off side is scrap, otherwise, it may be possible to get as far into the curve as possible and then withdraw the blade and approach the curve from the uncut end.

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. If you have ever attempted to cut thin sheet metal with a jigsaw, you might have noticed excessive vibration, and in some cases, the sheet may get bent and damaged.But before jumping in on this project, let’s talk about the safest ways to do it and how you can cut metal efficiently. Safety First 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.

ALWAYS make sure your power source is removed when switching blades. Either unplug your corded saw or remove the battery from your cordless saw. Never replace a blade while power is connected, no matter how confident you are. 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. 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!”Keep plenty of extra blades on hand, as cutting metal will degrade a blade faster than cutting a softer material like hardwood. The body of a bi-metal blade is made with spring steel or flexible carbon steel. But the cutting teeth are made of hardened high-speed steel that is welded or diffusion bonded onto the softer body. So the blade can cut harder materials without wearing down as fast.

If starting the cut at the edge, press the saw shoe firmly on the surface of the workpiece without the blade touching the metal. Slowly depress the trigger and once the blade is moving, glide it into the workpiece. It is important not to force the speed of the cut and just let the blade do the work. If starting the cut away from the edge of the workpiece, simply drill a hole large enough to insert the blade in and continue as above.You can use a jigsaw to cut sheet metal and metal pipes made of cast iron, steel, copper, aluminum, brass, etc. Jigsaws are awesome, versatile tools. They can make tight, precise cuts, and long straight runs with no distinction from a circular saw’s cut. As with most cutting tools, the type of blade you use is possibly the most important factor in how efficient your cuts will be. Whether cutting curves or lines with a jigsaw, ensuring you have the right blade for the application is essential for making clean, safe, and effective cuts. Specific materials require different types of jigsaw blades, including those with varying tooth pitches, sizes, and orientations. For example, blades with fine teeth are ideal for cutting metal, while those with larger teeth are more suitable for wood. Having the right blade for the material you’re working on will always ensure for maximum cutting performance.
