2. Craft & Performance
All drill bits of the M14 Diamond Arrangement Hole Opener Blue Silver Sand 8PC with Aluminum Case adopt high-temperature vacuum brazing technology, the core craft that supports the long service life of the M14 Diamond Arrangement Hole Opener Blue Silver Sand 8PC with Aluminum Case. The special diamond-shaped staggered silver grit structure on the cutting head of the M14 Diamond Arrangement Hole Opener Blue Silver Sand 8PC with Aluminum Case creates wider chip clearance gaps, rapidly discharging stone powder and effectively preventing drill clogging during continuous long-hour drilling. The bright blue anti-corrosion coating on the 45# steel body of the M14 Diamond Arrangement Hole Opener Blue Silver Sand 8PC with Aluminum Case isolates water and moisture, avoiding rust even under long-term wet drilling working conditions. The exposed silver diamond sand layer of the M14 Diamond Arrangement Hole Opener Blue Silver Sand 8PC with Aluminum Case maintains lasting cutting sharpness, and the tight vacuum brazing bond firmly locks diamond grit to stop shedding under high-speed rotation and heavy torque load. The thickened solid 45# steel base of the M14 Diamond Arrangement Hole Opener Blue Silver Sand 8PC with Aluminum Case resists bending and deformation, delivering vertical stable drilling without deviation to produce smooth clean round holes. The standard M14 thread interface of the M14 Diamond Arrangement Hole Opener Blue Silver Sand 8PC with Aluminum Case achieves seamless compatibility with global mainstream angle grinders, supporting both continuous wet drilling and short light dry drilling for flexible construction.
