About HSS Cobalt Drill Bit And Tungsten Steel Drill Bit

Due to the rapid development of CNC machine tools, the application of tungsten steel drill bits, that is, cemented carbide drill bits, has been greatly developed. Many factories use tungsten steel drill bits as much as possible, but because the background colors of tungsten steel drill bits and HSS cobalt drill bit is bright white, it is easy to confuse, and it is difficult for many people to distinguish.
1. The difference in weight is the simplest and most direct. Because the tungsten steel drill bit has a heavier proportion, the tungsten steel drill bit of the same specification is heavier than the HSS cobalt drill bit. This is one of the easiest methods.
2. From the difference in color, the tungsten steel drill bit is seriously bright and black in appearance, so it is also called tungsten steel. The HSS cobalt drill bit is bright and whitish in appearance.
3. Different from the coating, the coating color of the tungsten steel drill bit is purple, and the HSS cobalt drill bit is pure black or dim yellow.
4. From the price difference, the price of the tungsten steel drill bit is higher, and the price of the HSS cobalt drill bit is cheaper.
5. There are differences in use. Tungsten steel drill bits have fast cutting speed and long service life. HSS cobalt drill bits have a relatively short service life but are very easy to use.
However, the wood auger drill bit should be the most used. www.jeejatools.com
