Description
Premium MaterialThe micro drill bit set is made of high-quality tungsten steel, with high wear resistance, high hardness, not easy to bend, and has good milling and cutting performance.
High-precision Cutting EdgeThe micro drill bit adopts a nano-scale spiral cutting edge, which reduces the cutting force, prevents the drill from breaking, and improves the machining accuracy.
0.1-1.0mm Multiple SizesThis PCB drill bit set contains 10 different sizes: 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, different sizes to meet different needs.
Easy to UseMicro drill bits are designed with shock-proof design, stable and reliable engraving process, fast and clean work without burr, large chip removal space, low drilling heat, very practical.
Wide ApplicationThese tungsten carbide drill bits are ideal for drilling holes in printed circuit boards, CNC engraving plexiglass, amber beeswax, bakelite, jewelry, plastic and other precision drilling.
