HARFINGTON 3 Set (30pcs) PCB Drill Bit Set 1/8" Shank 0.9mm Tungsten Carbide Micro Twist Drill Bits Tools for Print Circuit Board Jewelry Plastic Wood Soft Metal

Long-lasting micro drill bits are made of tungsten carbide, providing a precise and easy experience, with high hardness, good toughness, wear resistance, high strength, resistance to bending and heat. The carbide material has cutting performance to ensure high working efficiency.With the spiral flute design, PCB drill bits can discharge chips more effectively, reduce cutting resistance, increase cutting speed and work efficiency, and reduce vibration to maintain the stability of the cutting process. Designed with a positioning ring to reduce machine adjustment time and increase efficiency.PCB drill bit is for the precision processing of jewelry, printed circuit boards, plastics, fiberglass, acrylic, wood, aluminium, soft metals and other materials. The drill bit has a precision cutting edge to maintain smooth cutting.Mini drill bits are widely used on PCB drilling machines, engraving machine, CNC lathes, machining center. 3.175mm (1/8 inch) shank diameter to fit most rotary tools. Take good control of your CNC speed. Use a coolant or lubricant to reduce friction and heat during drilling. Hold the drill bit steady and perpendicular to the surface for accurate drilling. Keep the drill bits in a secure case to prevent damage to the delicate cutting edges. Micro drill bits is easily twisted off.
