Feature(may vary by option.)

●PREMIUM MATERIAL - These mini drill bits are made of tungsten steel,carbide tipped drill bits with high hardness,high wear resistance, resistance to bending, anti-impairment.Replacements for your CNC machines and any Handheld tools.
●MEET YOUR NEED - Cutting edge diameter of these PCB Drill Bit Set: 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm.
●SHARP EDGE - End Mill Sets can milling groove and clean surface,a large scraps discharge space,little resistance and smoothly during the scraps discharge.These sets of tool can work quickly and cleanly.
●IMPROVE ACCURACY - The end milling engraving bits with shape cutting edge,reduce cutting force and prevent drill broken,improve the drilling accuracy.Attention: Dont use on too hard material,like high hardness iron.
●WIDE APPLICATION - The PCB drill bit sets are great for punching at printed circuit boards,cutting and engraving and worked on Acrylic, PVC, Nylon, Resin, Fiberglass,etc.

WARM TIPS:

1.The the color of the locating ring will be randomly.
2.Please be careful when handling for it very fragile, specially for size of 0.3mm 0.4mm 0.5mm, and TAKE CONTROL OF THE SPEED WHEN DRILLING.
3.Keep the vertical direction when drilling,not too hard.
