2. Craft & Performance
All cutting heads of the M14-7pc Golden Exposed Diamond Grain Drill Bit Set with Aluminum Case adopt high-temperature vacuum brazing exposed sand craft, evenly distributing high-hardness industrial diamond grit on the golden metal drill body. The open exposed grain structure of the M14-7pc Golden Exposed Diamond Grain Drill Bit Set with Aluminum Case accelerates stone powder discharge efficiently, effectively avoiding debris clogging and high-temperature burning even during long continuous dry cutting without water cooling. The uniform golden anti-rust coating of the M14-7pc Golden Exposed Diamond Grain Drill Bit Set with Aluminum Case resists erosion from stone dust and residual moisture on construction sites. Six multi-size core bits of the M14-7pc Golden Exposed Diamond Grain Drill Bit Set with Aluminum Case finish different aperture drilling tasks, while the matched 50mm conical chamfer tool polishes smooth arc edges for drilled holes to eliminate sharp burrs. The standard M14 thread connection locks tightly without shaking at high rotation speed, ensuring neat, crack-free holes every time you operate the M14-7pc Golden Exposed Diamond Grain Drill Bit Set with Aluminum Case.
