Things You'll Need
Work bench or steady surface
9-inch metal-cutting blade
Angle iron is a length of sturdy steel that is bent to a perfect 90-degree angle. To cut or shape an angle iron, you must use a blade that is designed specifically for cutting metal. If a wood-cutting blade is used on angle iron, the blade will quickly overheat and become dull. The blade may also cause the saw to become hot and possibly short-circuit. By using an angle grinder and an appropriate blade, you can easily cut any size angle iron.
Place the angle iron you intend to cut on your workbench or other level, sturdy surface. Decide where you want to cut and use a paint pen to draw a guiding line on one side of the angle iron.
Attach the 9-inch metal-cutting blade to the angle grinder. Plug in the angle grinder and put on your safety goggles.
Turn the angle iron onto one side and begin cutting from the top, slowly moving down the corner of the angle. Use the guiding line you drew for reference.
Continue cutting until you have split the angle iron into two lengths.
Repeat to cut multiple lengths of angle iron.
Do not attempt to cut angle iron with anything other than a metal-cutting blade. Always be careful when using power tools. Keep children and pets away from your work area, and also be careful with beverages or water.
