Long-lasting bits are made from tungsten carbide for precise and easy experience. Features high hardness, good toughness, wear resistance, high strength, resistance to bending and heat resistance. Carbide can run at higher speed than high-speed steel. Carbide material with good milling and cutting performance, can ensure high work efficiency. Suitable for drilling and engraving PCB, acrylic, plastics, fiberglass, wood, aluminium, soft metals. Used on PCB drilling machines, engraving machine, CNC lathes, machining center. The mini drill bits is easily twisted off. Use vertically and take good control of your CNC speed. Cutting edge provides smooth cutting, reduces cutting force, prevents drill broken, and improves the drilling accuracy. Spiral chip space design for fast and clean chip removal. The tool set can work quickly and cleanly, no glitches or scrap left. The positioning rings reduce machine adjustment time and increase efficiency.
