The drill bit is relatively common in our daily life. It is a rotating tool with cutting ability at the tip. Then the drill bit needs to be polished regularly, and the extra long wood drill bit is naturally no exception. So how to sharpen the drill bit better?
The axis of the drill bit should be inclined at an angle of 60° with the surface of the grinding wheel. This angle is the front angle of the drill bit. The wrong angle at this time will directly affect the size of the top angle of the drill bit, the shape of the main cutting edge, and the bevel angle of the chisel edge. This refers to the positional relationship between the axis of the drill bit and the surface of the grinding wheel. It should be 60°. This angle is generally more accurate. Here we should pay attention to the relative horizontal position and angular position of the drill bit before sharpening. The two should be taken into consideration. Don't neglect the angle to level the edge, or neglect to level the edge for the angle.
The above is the angle of the drill that we need to pay attention to when grinding the drill. TCT circular saw blades also need to be polished and maintained regularly, so they must be carefully maintained. www.jeejatools.com
