Cobalt Drill Bits – The Planet’s Toughest Drill Accessory
As you probably already realize, there are many different drill bits each with a specific usage. Strength is a big part of design differences, as drills are made specific to the hardness of material to be drilled through. Most bits you use are twist bits, a cylinder that has been cast or machined with grooves called flutes. Often, drill bits are coated with materials, including diamond powder and ceramics. But which are the very hardest drill bits? Cobalt steel drill bits make holes possible in metals a bullet wouldn’t penetrate. In fact cobalt drill bits can be used to manufacture rifle parts.
Cobalt drill bits are made from a steel alloy, and are a little different from standard high speed drill bits in that they contain more cobalt, hence the name – visit metal drill bits for additional tips relating to this subject area. A key characteristic they have is maintaining their cutting edge at extremes of heat. Most steel drill bits, while drilling through metals such as stainless steel, will lose their hardness and thus, the sharpness of the bit will be diminished. The edges will literally soften due to the intense friction. The advantage of the hardness is offset by an increase in brittleness, which can be worked around through careful usage. Even when using a cobalt bit, a lubricant should be used to keep heat build-up down – point your browser at electrical courses to get additional tips connected to this topic area.
The advantage of being able to drill through heavy metals is obvious, but be aware that not all cobalt drill bits are alike. The percentage of cobalt in the alloys varies depending on the manufacturers specifications. The lower percentage cobalt bits have greater heat resistance than the higher percentage ones, but the higher percentage bits have longer life.
Cobalt is used in steel alloys for its resistance to wear and corrosion. It does not reduce the magnetic properties of steel, which is very useful should you drop a cobalt drill bit, as you can find it with a magnet like you would ordinary drill bits. Alloyed steel is one of the wonders of modern science. It has applications that range from tank armor to spectacle frames to scalpels. The inclusion of cobalt in the steel composition is what gives these bits their distinctive and unique physical properties.
In industry cobalt drill bits are used to drill through hardened steel and other hard alloys like titanium. They can withstand heats up to 1,100 degrees and keep working where a lesser bit would soften and dull. The casting of the bits is done with a web design to increase the rigidity of the tool and to prevent snapping when going through abrasive materials.
