Need to cut through metal? Select a blade with a high-speed steel (HSS) tooth design. These blades offer superior durability and precision, particularly when working with thicker materials. For instance, a 18-tooth per inch (TPI) blade excels at cutting through steel pipe. Remember to always use the appropriate personal protective equipment (PPE).
Working with wood? Opt for blades with a higher TPI count, such as a 10-TPI blade for faster cuts in softer woods or a 6-TPI blade for tougher hardwoods. A coarser tooth pitch provides a more aggressive cut while finer teeth ensure cleaner cuts. Consider the wood’s density when making your selection; a harder wood requires a more robust blade.
For cutting plastics and composites, a bi-metal blade is your best bet. Its construction, combining high-speed steel teeth with a flexible body, allows for versatile use. This combination provides clean cuts and reduces the likelihood of blade breakage. Pay close attention to the blade’s length to ensure proper fit with your saw.
Finally, always inspect your blade before each use. Check for any signs of damage like bent teeth or cracks. Damaged blades can result in unsafe operation and inaccurate cuts. Investing in a variety of blades tailored to different materials ensures a smoother, more productive workflow.
