2. Craft & Performance
All bits of the M14 Diamond Arrangement Hole Opener Matte Black Gold Sand 8pc use high-temperature vacuum brazing craft, the core manufacturing process that guarantees long service life of the M14 Diamond Arrangement Hole Opener Matte Black Gold Sand 8pc. Its signature diamond staggered grit layout on the cutting head of the M14 Diamond Arrangement Hole Opener Matte Black Gold Sand 8pc creates wider chip clearance gaps, accelerating stone powder discharge and effectively preventing drill bit clogging during continuous drilling work. The matte black anti-rust coating on the steel body of the M14 Diamond Arrangement Hole Opener Matte Black Gold Sand 8pc isolates moisture and water, avoiding oxidation even under long-term wet drilling operations. The golden exposed diamond sand layer of the M14 Diamond Arrangement Hole Opener Matte Black Gold Sand 8pc maintains consistent sharpness, and the tight vacuum brazing bond prevents diamond grit shedding under high-speed rotation and heavy torque. The thickened 45# steel base of the M14 Diamond Arrangement Hole Opener Matte Black Gold Sand 8pc resists bending and deformation, delivering stable vertical drilling without wandering off track. Standard M14 thread interface of the M14 Diamond Arrangement Hole Opener Matte Black Gold Sand 8pc realizes seamless matching with global mainstream angle grinders, supporting both wet drilling and short-time light dry drilling for flexible construction.
