bit chip space is large: small chip resistance
chip and smooth, heat a small drill, drill reduce pollution
extraordinary cutting edge sharpness
As a result of nanotechnology and advanced grinding technology
bit more sharp cutting edge than before, can reduce the cutting force
reduce the broken drill rate, improve the hole wall quality
