Materials and characteristics of stainless steel special drill bits

Stainless steel is a common material in life nowadays, and it is loved by people because of its light weight and high hardness. Stainless steel is hard, difficult to destroy and difficult to transform, so the drill bit chosen is very important, so which drill bit is suitable for stainless steel?

1, In general, cobalt-containing high-speed steel drill bits are very common in the market. Although the efficiency is not high, but it is still possible to drill stainless steel, and the price is relatively low, so it is a common drill bit that people use.

2, titanium-plated high-speed steel drill bits can also be used to drill stainless steel, can adapt to a relatively fast speed, high hardness, the face of stainless steel such hardness of the material can be relatively simple to drill the bit. 

3, High performance carbide drill bits can also be used to drill stainless steel. Carbide stainless steel special drill bit has high efficiency and hardness, and can cope with harder materials, but the price is high.

In addition, when drilling stainless steel, you should not touch the drill bit with your hands. A fast rotating drill bit is dangerous and can easily injure your hand. Stainless steel is hard, so don't be in too much of a hurry when drilling. Take your time, there is no drill bit in one place, and drill part of it first before drilling. When drilling stainless steel, the drill bit will generate a lot of heat due to the fast friction between the two. At this time, stainless steel and the probe is very hot. Do not touch easily with your hands to avoid burns. After use, the drill bit should also be cooled for a period of time. After the drill bit is completely cooled, the drill bit should be put away.

Stainless steel drill bits mainly include cobalt HSS bits, titanium-plated HSS bits and cemented carbide bits. These bits are hard and suitable for drilling stainless steel.
