Customer Rock Information Feedback: Although our rock is not classes as extremely hard it contains a lot of pyrite, some quartz and some iron / magnetite which makes it very abrasive. Due to the abrasive rock we only use round buttons. Our understanding is that a lot of the wear to our bits occurs due to re-grind of rock cuttings which we find is usually addressed by ensuring a lot of water is delivered through the face flushing holes and that there are adequate flushing grooves cut into the face and gauge of the bit matrix. The ground condition is generally very competent so we do not require retrac style bits.
Customer Current Bits Design: Our current bit design is 6x 10mm gauge buttons and 3x 8mm centre buttons. I am unsure if you are aware of the grades of Mitsubishi carbides but we have found that MG10 performs the best in our ground condition (as per the attached brochure). Our bit design is similar to ‘type 23’ however this too has been customised specifically for our ground to have more room for flushing away cuttings.
Smaple Bits we sent for testing: 10x SR35 45mm bits with round buttons for a demonstration. 10x R32 samples of different round carbide button grades to trial. Diameter of a brand new 45mm bit to be 47mm
