Carbide drills and cobalt high speed steel bit, which is good? What's the difference between these two materials?
The hard alloy bit too brittle is not recommended to use the titanium cobalt drill hardness is 12 degrees lower than the hard alloy but the impact is far better than other aspects of hard alloy, so I recommend the titanium cobalt drill, processing all kinds of materials, as long as the titanium cobalt drill deal, hard alloy as the game, looking for experience in practice, there are the problem can contact my 12 years of experience in fitter
The two materials are not good or bad, the key is to look at the application!!Carbide drill, high hardness, wear resistance, high efficiency, toughness slightly worse, therefore, the rigidity of the machine tool and spindle runout and speed are required!Cobalt high speed steel including ordinary high-speed steel, good toughness, edge processing can be very sharp, more suitable for processing some sticky materials, of course, low strength materials will be nothing difficult, but its high temperature resistance, wear resistance is relatively poor, the drilling speed is not high!!Therefore, the choice of drill or according to your working conditions to choose,
This is the first use, each one has its own merits, hard alloy with high hardness, suitable for high speed drilling and high hardness materials, and high cobalt high speed steel has good toughness, suitable for low hardness material, suitable for drilling slower machine.
