#4. Tips When Cutting Iron

  • The iron cutter can cut the steel bar easier if it has the shortest cutting length. You should cut in the thinnest part of the bar.
  • The pressure can’t help to cut the iron faster. Instead, heavy pressure will cause the engine to run slower and wear out the cutting blades so you don’t need to press too much while running the machine.
  • Cleaning the blade shield helps the iron slag fall off and does not fall on the blade when the machine is running due to high speed of blade rotate.
  • Use a wood panel to prevent stain on the floor in case of using an angle grinder on a concrete substrate.
  • Use a square meter to check whether the cutting blades are perpendicular to the cutting table.
  • Never use a table or pillow for a bundle of steel on either side of the blade. This will cause the iron to be ham mocked, causing the blade to bend or jam.
  • To create an accurate cut, use a small pencil to mark the position and exact cross section on the surface of iron, and place it in the correct position on the cutting table. If the mark is too hard to see, you can replace by the tape measure. Tape measure helps you to create the most accurate cutting lines, ensure the required size.
  • Concerning the long and heavy iron, you can use the hammer to knock the saw to locate the mark, then tighten the clamp and cut with moderate pressure.
