Specification Brand : Hyuduo BulletPoint1 : 【Strong Drilling Ability】Straight shank drills can obtain greater drilling capacity under the same torque, and the special purpose of the circuit board is suitable for most operating environments. BulletPoint2 : This PCB drill bit set is very suitable for 3D printer nozzle cleaning, amber beeswax, circuit board, CNC engraving plexiglass, jewelry, metal plastic and other precision drilling. BulletPoint3 : Straight shank drill bit can obtain more drilling capacity for the same torsion. BulletPoint4 : The spiral PCB drill bit set is made of hard alloy which is not easy to corrode, but the drill bit is too thin and easy to break. Please be careful when using it. BulletPoint5 : Drill bits with sharper cutting edge, reduce cutting force and improve the drilling accuracy.
