Testing Bits R32/SR35 45mm Threaded Button Bits
date : 2019-04-22Views : 0
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
