Apply protective oil before using woodworking milling cutter

When working with a woodworking milling cutter, you must pay attention. Its milling cutter is very easy to detach from the spring clip, or even fall off. This situation is not uncommon. Therefore, if you use the milling cutter frequently, you must coat it with anti-rust oil. This oil film can protect its spring clip and form a layer of tightening force to ensure that the milling cutter does not fall off, so that it will not harm the user. Nor will the product be scrapped.
