HIGH ACCURACY: Tip spiral flute tungsten carbide drill bits with shaper cutting edge, reduce cutting force and prevent drill broken, improve the drilling accuracy
SMOOTH CHIP EVACUATION: Drill bit has a large scraps discharge space, little resistance and smoothly during the scraps discharge
EASY TO USE: The micro drill bits are easy to change out and do a great job cutting through the PCB for solder holes
HIGH HARDNESS: Carbide tipped drill bits with high hardness, high wear resistance, high strength, resistance to bending, anti-impairment and long tool life
WIDE USE: The print circuit board drill bits are great for drilling PC boards, plastics, fiberglass, wood, soft metals, etc.
