35 mm Matrix Drill Bit | 20 mm Marble Customer Test
Marble is the fourth material in this customer-test series. Watch our Ø35 mm vacuum-brazed matrix diamond drill bit drilling 20 mm thick marble. The customer used the same drill bit across the quartz, granite, DEKTON and marble tests.
Original customer footage, with pauses retained. This series documents the customer tests rather than a controlled speed or service-life comparison. Use appropriate dust controls and protective equipment.
