What should we pay attention to when using saw blade

1. When the saw blade is welded, the part of the alloy connected with the blade should not be too brass as copper. There should be no false welding. The solder should be a little white, with a thin line. It is clean and clean. There is no green copper rust.
This has something to do with safety. Nobody wants to fly out of the alloy blade when cutting wood. It's comparable to the power of a small-caliber rifle.
2. Look at the four sides of a good saw blade that have been ground. They have two sides, front teeth and top surfaces. They are smooth and smooth, without concave and convex, with good consistency, sharp edges, bright surfaces, no leak grinding or no grinding. They are high before and low after grinding, and they will paste wood.
3. Look at the surface of the chip, the effect of polishing should be known to all. The smoother the friction coefficient is, the less easy it is to stick sawdust or stick wood. It sells well. You can take a knife-edge ruler to measure the plane, not as uneven as a bowl.
4. If there are conditions, you can go up and saw and turn. There is no noise and no swing when idling. (At this time, pay attention to safety) Rotate slowly with your hands and measure the radial beat.
That's basically the way it is. As for professional testing methods, they rely on equipment and measuring tools to do more in-depth work.
The export saw blades are all 15.88 mm and 25.4 mm medium holes. The domestic saw axle seems to be 20 or 18.
For good cutting effect, 7 inches can buy 40 or 60 teeth, and 7 inches 16 or 24 teeth can be used for blanking.
Ten inches 24 teeth, 40 teeth can be used for cutting, precision sawing can be used, 80 teeth or 100 teeth.
The cutting effect of a good saw blade can be said to be better than that of a planed surface, with no burrs on its edges, especially on hardened wood. That's just what happened.
Blessing to buy a good saw blade.
