The micro drill bits set have strict workmanship, fine grinding technology make the cutting edge of the drill sharper, which is suitable for PCB, SMT, CNC, mold, sculpture, plastic, copper, stainless steel.
It has a large scraps discharge space, little resistance and smoothly during the scraps discharge, which is perfect for fine drilling of hard materials for model engineering, jewelry repair, and craft work.
The drill bits is made of high quality materials, high wear resistance, high hardness, not easy to deform and rust, strong and durable, which have a great job cutting through the PCB for solder holes.
The micro drill bits can reduce cutting force and broken drill, improve the quality of hole wall, very practical.
