Micro PCB Drill Bit Set 1.2mm 1.5mm, 1/8" 3.175mm Shank Tungsten Carbide CNC Engraving Print Circuit Board Drill Bits Rotary Tool 20pcs

Key Features

• Drill Bit Size Cutting edge diameter 1.2mm / 0.047", 1.5mm / 0.059"; shank diameter 3.175mm / 1/8"; overall length 38mm / 1-1/2". With sharp cutting edge, milling groove and clean surface, these tool sets work quickly and cleanly, no glitches or scrap left.
• Tungsten Carbide Tool 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.
• Wide Applications Suitable for drilling PC boards, plastics, fiberglass, wood, soft metals. Fit for PCB drilling machines, engraving machine, CNC and high precision special drilling equipment. Long-lasting bits are made from tungsten carbide for precise and easy experience.
• Sharp Cutting Edge Provides smooth cutting, reduce cutting force and prevent drill broken, improve the drilling accuracy. Provide good cutting strength and drilling effect. Spiral chip space design for fast and clean chip removal.
• Tips The drill bits are too tiny, so it is very fragile for handling. Please be careful and take good control of your CNC speed. 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.
