A metal drill has two sharp cutting edges at the tip and is usually made of HSS, which is the short form for high-speed steel. A metal drill is suitable for various metals such as iron, steel, aluminum, brass, copper, etc.. It can also be used to drill soft materials such as plastic or wood.
Metal Drill Features:
Cutting: two sharp cutting edges
Drill speedThe correct drill speed is very important to keep the wear on the drill low and to get the best possible drilling result, which should be the main goal. In order to determine the correct speed, you have to know the material you want to drill into and the diameter of the drill you want to drill with.
The basic principle is:
Larger Drill => Lower Speed
Harder Material => Lower Speed
In order to achieve the best possible drilling result in metal, it is advisable to use coolant. Drilling heats up the drill hole and the drill very quickly, if you see that the drill or the metal you are drilling into turns blue, it is already too late. The drill can break and the hole can deform.
Tip: In case of doubt, drill at low speed and little pressure. At the same time, always cool sufficiently with coolant.
The speed table for different metals gives you the exact speed required for the drill diameter used.
