In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a prevent saw bit of sawdust adhesion, includes the saw bit body, the through-hole has been seted up to the centre of a circle position of saw bit body, and the solid fixed ring of inner wall fixedly connected with of through-hole, the outer wall equidistant a plurality of that is provided with of saw bit body leads to the groove, and the outer wall of following of saw bit body encircles and distributes and have a plurality of blade, two surfaces of saw bit body have all been coated and have the coating, and the coating includes upper coating, stable layer, basic unit, stereoplasm layer and lower coating, upper coating, stable layer, basic unit, stereoplasm layer and lower coating are arranged by last under to in proper order on the surface of saw bit body.

Preferably, the stabilizing layer and the hard layer are symmetrical with respect to a horizontal center plane of the base layer.

Preferably, the upper coating and the lower coating are both made of teflon, and the teflon has anti-sticking property, so that sawdust is prevented from being stuck on the surface of the saw blade when wood is cut.

Preferably, the blade is made of tungsten carbide, and the tungsten carbide has extremely strong rigidity, so that the wood can be easily cut.

Preferably, the base layer is made of carbon manganese steel, and the base layer is moderate in hardness and has certain toughness, so that the saw blade cannot be easily broken.

Preferably, the hard layer is made of nickel-chromium alloy, commonly known as stainless steel, and has the characteristics of rust prevention and high temperature resistance, so that the saw blade cannot be broken due to high temperature generated by high-speed cutting in the use process of the saw blade.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model takes the carbon manganese steel as the material of the base layer, the carbon manganese steel has moderate hardness but certain toughness, so that the saw blade can not be easily broken;

2. the bottom of the base layer is fixedly connected with a hard layer made of nickel-chromium alloy, the nickel-chromium alloy is commonly called stainless steel, and the saw blade has the characteristics of rust resistance and high temperature resistance, so that the saw blade cannot be broken due to high temperature generated by high-speed cutting in the use process of the saw blade;

3. the utility model discloses all be coated teflon as upper coat and lower coating at the upper surface of saw bit and lower surface for when cutting timber, can prevent effectively that the saw-dust from gluing on the surface of saw bit.
