This tungsten steel drill bit is mainly suitable for high precision professional drilling equipment such as PCB drilling rigs. PCB Drill Bits Set are great for punching at printed circuit boards, 3D Printer Nozzle Cleaning, CNC engraving plexiglass, Amber beeswax, bakelite, jewelery. Suitable for drilling and engraving PCB, acrylic, plastics, fiberglass, wood, aluminium, soft metals. Used on PCB drilling machines, engraving machine, CNC lathes, machining center.

Features
Can ensure high work efficiency. Carbide can run at higher speed than high-speed steel. High speed steel shank provide high hardness and good toughness for wear resistance.
Carbide PCB Drill Bits replace your CNC machines and any hand held tool. Large drill bit chip space, chip resistance, chip smooth, small drilling heat.

Tips
1. PCB drill bits which below 0.5mm are easy to break because they are small and thin. It is recommended to be careful when using them.
2. The longer the length of the tool clamped by the chuck, the better. If the clamping length is shorter, you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life.
3. Combined with the material to be processed, select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.
