- Cut in Stages: For thicker asphalt, it's best to cut in multiple passes, gradually deepening the cut. This prevents overheating the blade and ensures a cleaner cut. Cutting asphalt in stages, particularly for thicker sections, is a crucial technique for achieving clean, precise cuts while minimizing the risk of overheating the blade and damaging the asphalt. This method involves making multiple passes with the cutting tool, gradually increasing the depth of cut with each pass, rather than attempting to cut through the entire thickness of the asphalt in a single pass. When cutting asphalt in stages, the first pass should be shallow, typically no more than one-quarter to one-third of the total thickness of the asphalt. This initial pass creates a groove that guides the blade for subsequent passes, helping to prevent the blade from wandering or skipping. It also reduces the amount of stress on the blade, minimizing the risk of overheating and damage. After making the first pass, inspect the cut line to ensure that it is straight and accurate. Make any necessary adjustments before proceeding with the next pass. For the second pass, increase the depth of cut slightly, again typically by no more than one-quarter to one-third of the total thickness of the asphalt. Continue making passes, gradually increasing the depth of cut with each pass, until you have cut through the entire thickness of the asphalt. The number of passes required will depend on the thickness of the asphalt and the power of your cutting tool. Cutting asphalt in stages helps to prevent overheating of the blade by reducing the amount of friction and heat generated during the cutting process. When the blade is forced to cut through a thick section of asphalt in a single pass, it can generate a significant amount of heat, which can damage the blade and reduce its lifespan. By cutting in stages, the heat is distributed over multiple passes, allowing the blade to cool down between passes. This technique also helps to ensure a cleaner cut by minimizing the risk of chipping and cracking of the asphalt. When the asphalt is cut in a single pass, the force exerted by the blade can cause the material to fracture or chip along the cut line. By cutting in stages, the force is distributed over multiple passes, reducing the stress on the asphalt and minimizing the risk of damage. By cutting asphalt in stages, you can achieve cleaner, more precise cuts, extend the lifespan of your cutting blade, and reduce the risk of damaging the asphalt.
- Cool the Blade (If Necessary): Some diamond blades are designed for wet cutting. If yours is, use water to cool the blade and reduce dust.
