The 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.
Perfect for building body shells when using screws for attaching accessories
The 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.
Micro 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.
This drill bit set contains 10 different sizes: 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, different sizes to meet different needs.
