Plug in the saw and if it has adjustable speed settings, select the appropriate speed for cutting metal.

Familiarize yourself with the tool’s operation if you have not used it before, and consider doing a few test cuts on a scrap piece of metal to get a feel for the saw. Once you are confident that your cutting tool is prepared and you are ready to proceed, you can move on to making the actual cut.

Step 3: Start Cutting the Diamond Plate

Position the cutting tool at the edge of the marked line and gently lower it onto the diamond plate. If using an angle grinder, make sure to start with a shallow cut to avoid excessive vibrations that could affect your accuracy. For circular saws, begin by making a small notch on one side of the cutting line before moving on to complete the cut.

Keep steady pressure on the tool as you follow along the marked line, keeping it straight and avoiding any sudden movements. Take extra care when approaching corners or curves in your cuts, making sure to maintain a smooth and even pace throughout.

Depending on your project’s requirements, you may need to make multiple passes with the saw until you achieve a clean, precise cut.

Step 4: Use Shears or Snips for Smaller Cuts

For smaller or more intricate cuts on the diamond plate, using metal shears or snips can be more practical and precise than electric saws.

Begin by positioning the shears or snips at the edge of the marked line where you intend to start your cut. Slowly squeeze the handles together to engage the cutting blades and start making your cut along the marked line.

Ensure that you maintain a steady hand and consistent pressure while cutting to avoid jagged edges or deviations from your marked line.

If your project requires cutting through tight corners or bends, opt for aviation snips, which are specifically designed for more agile and controlled cuts. Remember to follow the contour of your marked line carefully, especially when maneuvering around the raised diamond pattern.

Step 5: Save and Use Scrap Pieces

When cutting diamond plates, you will likely end up with some leftover scrap pieces that you can save and use for other projects.

Step 6: Consider Using a Jig

For more complex cuts that require precise angles or curves, using a jig can be beneficial. A jig is a device that helps guide your cutting tool along specific paths or shapes, ensuring clean and accurate cuts. You can purchase pre-made jigs or make your own using scrap pieces of wood or metal.

To use a jig, simply place it on top of the diamond plate with the desired shape or angle aligned with the marked line. Then, use your cutting tool to follow along the jig’s edge, guiding you in making an accurate cut.

Step 7: Use Lubricant for Thicker Diamond Plate

When cutting thicker diamond plates, applying a lubricant can help reduce friction and heat build-up, ensuring a smoother and more efficient cut. Lubricants such as cutting oil or even soapy water can prevent the cutting blade from overheating and becoming dull prematurely.

Before you start cutting, apply the lubricant along the marked cutting line of the diamond plate. Reapply the lubricant periodically throughout the cutting process, as needed, to keep the blade cool and minimize resistance. Remember to wipe away any excess lubricant after completing your cut to maintain a clean and safe work environment. 

Step 8: Clean Up and Inspect Your Cuts

Once you have completed your cuts, take a moment to clean up any debris or scraps from your work area.
