我真的沒有想到，鑽頭上套一個塑料管，竟然這麼厲害，漲見識了【我愛電器維】

I really didn't expect So put a plastic tube on top of the drill like this I didn't expect it to be so powerful and easy to use Many people use this hand drill For this rear plate or When punching holes in stainless steel Often it is just that one eye has not been penetrated. Burned out the drill bit. But there are many people Just use the same drill bit It's ok to sit on such a thick steel plate in one breath Consecutive, punch many holes It won't burn out the drill either. including such Same goes for stainless steel It's easy to drill through without burning the bit So where is the root cause? Let me share with you today how Just use a drill bit to make many holes in one go won't burn the drill bit on it First of all we are Give it the drill before you drill the hole Let me share this method with you after taking it down And then we are on this drill bit put a heat shrink tube on it Just put it in this position The next step is to bake it with a lighter slightly toasted just let it stay on this drill Don't overcook it and that's it what's next Let's put it back on the hand drill After installation, in Whether it's this rear steel plate that drills holes for it when drilling stainless steel Before drilling first First put some sewing machine oil on the drill bit It should be dripped on the upper part of the place drip on both sides of its bit After dripping and then we'll see Next, drill up like this You see when there is no drilling above this sewing machine oil it will constantly dripping down uh it can act as a lubricant this time we start just drill up when drilling Hold down this hand drill with your hand and press down hard Let's see how the drill works Look at this froth very fast also very fast let's see Such a thick steel plate will soon break through Look at the speed of rotation is very fast we are in stainless steel Or when punching holes in this kind of thick steel plate Because thicker holes take longer If you drill directly like this after a long time It's easy to burn out this bit So everyone will use this method in the future It can solve the problem of burning the drill bit See if you drill a few times, you can see that it will be pierced soon How to get through it, right? And there's nothing wrong with the drill Well Add a little sewing machine oil Its role is to play a uh cooling effect What about this method? Whether it is this very thick steel plate or this stainless steel Uh, you can easily punch several holes in one go It won't burn out the bit on the top either. This method is very practical OK, thank you for watching the video
