Flat teeth: Flat teeth are mainly used for slotting and ordinary wood sawing. Usually, the number of teeth is large, with a 5 degree bevel angle, and the surface quality of the cut is good.

Flat teeth: Flat teeth are mainly used for slotting and ordinary wood sawing. This saw blade has lower cost and is the simplest to grind.


Left and right teeth: The left and right teeth are characterized by sharp cutting of long fibers. They are used in solid wood processing and are often used for stripping and cross sawing of various soft and hard materials and particleboards. The left and right teeth (humpback teeth) with limited depth of cut protection are suitable for longitudinal cutting of various slabs with knots.


Flat ladder teeth: The use of flat-blade saw blades can achieve high sawing quality, suitable for sawing of various veneer panels, which can effectively reduce chipping and sawing. The flat-toothed serrated alloy has high strength and is not easy to collapse, so the sawing rate is large, and it is widely used in non-ferrous metal sawing such as aluminum alloy.


Left and right flat: The left and right flat teeth are mainly used for slotting and wood cutting with low requirements, and the slot width is large.


Left and right and left and right: The left, right, left and right flat are mainly used for the precise cutting of the cut surface. Usually, the number of teeth is large, with a 5 degree bevel angle, and the surface quality of the cut is good. It is often used for sawing of photo frames, speakers, acrylics and other materials.


Left and right helical teeth: Small diameter left and right helical teeth are usually paired in the edge banding of the edge banding machine. Large diameter left and right helical teeth are often used for trimming of sheets.


Three left and one right and three right and one left: This tooth shape is usually used for the trimming of the plywood factory.


Inverted ladder teeth: The inverted ladder teeth are mainly used for pre-grooving of the panel saw. When sawing double-faced wood-based panels, in order to ensure the integrity of the upper and lower veneers, the pre-grooving saw must complete the grooving of the bottom surface before the main saw blade is sawn to prevent the kerf from collapsing.
