Button bits has higher technology, much longer primary grinding time and higher drilling efficiency while comparing with taper chisel bits and taper cross bits, so that the bit is popular among the users.
According to the tungsten carbide insert, bits can be divided into the types of hemispherical , conical and parabolic , etc.
Button bits with hemispherical is for high bearing capacity and abrasive resistance while conical and parabolic are for high drilling speed and low abrasive resistance.
When drilling, adjust the parameters of impulse and rotary with the standards of no jamming, high drilling speed and no bend of tapered drill rods.
Check the rock drill bits after each drilling. If the s are seriously worn, replace the bits timely to ensure the drilling speed. If it’s possible, grind the bit for reusing. Replace the bits once the taper worn, otherwise the s would be seriously abraded and even jammed.
