Oscillating multi-tool blades are commonly made of the following materials:
High-Carbon Steel (HCS)
High-carbon steel is often used for cutting softer materials like wood, plastic, or drywall. It’s less durable and more prone to wear than other materials but tends to be more affordable.
High-Speed Steel (HSS)
High-speed steel is harder and more durable than high-carbon steel, making it a good choice for cutting harder materials like metal or for tasks that generate a lot of heat. It’s a compromise between HCS and Bi-Metal blades in terms of performance and cost.
Bi-metal blades combine a high-speed steel cutting edge with a high-carbon steel body for a good balance of durability and cutting ability. They can cut a wide range of materials, including wood, metal, and plastic, and are more heat and wear-resistant than HCS or HSS blades.
Carbide-Tipped or Carbide Teeth
These blades have a high-carbon steel or bi-metal body, but the cutting edge is tipped with carbide. Carbide is an extremely hard material that can withstand cutting very hard materials like hardened steel, concrete, or ceramic tile.
These blades have diamond particles attached to the cutting edge, making them ideal for cutting materials like tile, stone, and glass. Diamond is one of the hardest materials on earth, which allows these blades to cut through hard, brittle materials without chipping or cracking them.
Remember, the blade’s material should match the material you’re planning to cut for the best performance and longevity of the blade.
