2. Craft & Performance
All drill heads of the M14-8PC Aluminum Case Diamond Drill Bit Set adopt mature high-temperature vacuum brazing craft, which firmly locks industrial diamond grains on the bright blue metal substrate without grain shedding during long-time cutting. The open exposed sand cutting surface of the M14-8PC Aluminum Case Diamond Drill Bit Set quickly discharges stone and tile powder, effectively preventing clogging and high-temperature burning even under continuous dry cutting without cooling water. The smooth blue anti-rust coating of the M14-8PC Aluminum Case Diamond Drill Bit Set isolates erosion from stone dust and damp environment on construction sites. Eight core bits with different calibers inside the M14-8PC Aluminum Case Diamond Drill Bit Set meet diversified aperture demands, ranging from tiny 6mm micro holes to large 68mm mounting holes. The precise M14 thread locking structure stays stable under high rotation speed, enabling crack-free, smooth holes every time you use the M14-8PC Aluminum Case Diamond Drill Bit Set.
