【High Quality Material】The micro drill bit set is made of high-quality tungsten steel, which has high wear resistance, high hardness, and is not easy to bend. The anti-vibration design of the blade makes it stable and reliable during the engraving process, and has good milling and cutting performance.
【High Precision Cutting Edge】The small drill bit uses a nano-level spiral cutting edge to reduce cutting force, prevent the drill bit from breaking, improve processing accuracy, and have no burrs or debris.
【0.3-1.2mm Multiple Sizes】This PCB 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 can meet different needs.
