If the blade stagger, sawing wood, saw the road is very wide, not only pulled back and forth more effort, and can reduce friction and prolong the life of the saw. Have experience in carpentry, know to saw round things, should use the saw blade is narrow, toothed tilt angle larger saw. Because staggered sawtooth the larger the angle, the kerf is large, it can be very flexible to let the saw along the circle line pull. So saw arc bending or irregular things, suitable serrated stagger angles larger saw. The size of the gradient staggered sawtooth, called "saw how much".
From the end of the saw blade, steel bars along the past are not found in a zigzag plane. Because the light has sharp teeth saw, not useful, must take a sharp left oblique, a center (called fixed gear), a right oblique, so that a group of three, a group of three. One after another lined up. So with sawtoothIf not completely parallel to the left and right zigzag staggered, then saw saw it exactly equal to the thickness of the saw blade, and the wood will stick very tight, not easy to pull back and forth, saw them very laborious. At the same time, due to the friction between the blade and the wood, will make the saw heating "annealing". It is easy to make the blade broken.
Saws are not serrated, they are not called sawsLegend has it that Luban was scratched by jagged leavesFrom the tooth, two teeth are inclined surface. But a steep slope, a slope is relatively slow, a steep working face, because of its steep cutting can do more in sawing wood, improve work efficiency; a relatively slow is the slope with circular saw, do more slowly, can make the back saw more effort.
