Cobalt Alloy Drill Bits – Possibly The Toughest Drill Bits
Of the many types of drill bits, every one has a specific use it was designed for. Strength is a big part of design differences, as drills are made specific to the hardness of material to be drilled through. The vast majority of drill bits are cast with spiral grooves. Often, drill bits are coated with materials, including diamond powder and ceramics. Other special drill bits are designed to penetrate the hardest materials known to mankind. 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 – pay a visit to metal drill bits for more info regarding 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. They can literally start to melt due to the friction. The superior strength of these drill bits does have a counterbalancing weakness: they are more brittle or breakable. However there are ways of working around this. Even when using a cobalt bit, a lubricant should be used to keep heat build-up down – pay a visit to electrician training courses for more info on this subject area.
One thing you should be aware of is that cobalt bits differ in their strength. The percentage of cobalt is different in specific varieties of these bits. The lower percentage cobalt bits have greater heat resistance than the higher percentage ones, but the higher percentage bits have longer life.
Although cobalt produces a steel alloy that is much harder than the norm one great feature is that it does not change the magnetism. That means that if you drop your bit you can find it with a magnet as you would other 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 cobalt in the steel alloy sets these bits apart from their high-speed steel brethren.
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. In addition these bits are often cast in a layered framework to further enhance strength and decrease the chance of breakage.
