Have you ever wondered how saw blades are made? What are the materials and what makes them so sharp? You will have all the answers you need in this article below!
How saw blades are made?
Step 1: Cut and heat-treat the blade
Every saw blade begins with the material called raw steel. It can be spring, carbon-alloy, or high-speed. For more advanced saw blade profiles, it’s possible to customize the metal material.
There are two ways to cut the blade. Cutting using water is the act of letting water with enormously high-pressure cuts through metal, while laser cutting is offered for cutting precision.
Once the blade is cut, it will go through multiple steps such as:
Hardening: Each kind of metal will decide how long it takes for them to stay in the hot temperature. Among all the factors, time is the most primary one in the solidifying step, and it’s pivotal to have the blade stayed under heat for a specific time. For example, iron-based steel is heated at 1,750 degrees Fahrenheit in a furnace, requiring remaining in the heat for roughly 1 hour.
Quenching: When your sharp blade has invested enough time lounging in the heater, immediately cool it by placing it into the water. Again, time plays a huge role in producing active quenching.
Tempering: When your blade has arrived at the room temperature, it’ll reach the state where its hardness is maximum. It will take roughly 4 hours for the blade to go back to the room temperature entirely before moving on to the next step.
Step 2: Grind and sharp the blade
When your saw blade is appropriately tempered, it’s time to grind and sharp the blade.
Grinding requires first-hand relieving the tension inward the blade. Depending on the blade’s material, this process can be utilized automatically by supported machines or manually by mechanical engineers.
In the end, your new cutting blade is ready for sharpening by both robotized and manual granulating and honing techniques.

Step 3: Quality-control measurement
When it comes to quality-control checks, it’s not an automatic task anymore. Any blade not perfect enough for the required standard is removed to preserve the outcome quality. The qualified saw blades will be installed to saws and transported for further shipping processes.
