An angle grinder is basically an electric motor which rotates an abrasive wheel at a speed of 10000 rpm to 15000 rpm. Bigger wheels tend to rotate slowly. It is recommended that, with patience and practice along with the right steps, anyone can use an angle grinder for making a straight cut in metal sheet or heavy plate. One of the advantages of using angle grinders is it can be easily held in both hands.
Correct Steps of Usage of an Angle Grinder
Measure where you want to make the cut: Measurement is the base for an accurate cut using an angle grinder. One must use a sharpie and make a small mark in order to spot the starting point. One can also use a soap stone for this purpose. The user must remember that, the cutting blade is 1/16 inch thick, so considering the tolerances align your cut so it stays just outside the line.
Draw a Line: Once you have your mark ready for the measurement, take a square or ruler for making a straight line along the path where you will make the cut.
Score the Line: Next step is to take a straight piece of scrap and line it up along the marked line. Make sure that the scrap piece should be close to 1/8" from the line for allowing the thickness of the cutoff wheel. As the scrap is lined up, clamp it down safely. Now, wear your leather gloves, goggles as well as hearing protection, and switch on any of the Bosch angle grinders. Make the wheel follow the line and score the metal in accordance with the angle grinder.
Follow the Score Line: The user needs to make sure the cutting remains fixed within the score line. Also, on thicker metal like a 1/4" plate, it would be perfect to place it in the vise and aim for the cut vertically.
Analyze the Cut: Once the cut is finished, analyze it using your square. If there is any sort of error, you can always correct it using the wheel grinder and easily grind it to fix it. If you were already careful, there would be only a little effort to put. Moreover, if you are skilled with the grinder, you can utilize the edge of the cut off wheel to easily knock off the burs.
Final Say: The use of angle grinders to cut metal is not that easy, so make sure that you are well aware of the exact steps to complete the task carefully without getting hurt.
