PCB Drill Bits Set

This tungsten steel drill bit is mainly suitable for high precision professional drilling equipment such as PCB drilling rigs. The PCB Drill Bits Set is ideal for punching at printed circuit boards and can also be used for 3D Printer Nozzle Cleaning, CNC engraving plexiglass, Amber beeswax, bakelite, jewelery, metal plastic and other precision drilling applications. In addition to drilling, these circuit board drill bits can also be used for cutting and engraving on materials such as Acrylic, PVC, Nylon, Resin, Fiberglass, etc. The PCB Drill Bits are made of high quality tungsten steel, which makes them highly resistant to wear, with high hardness and bending strength, ensuring long-lasting performance and high working efficiency. The seismic design on the blade edge enables the drill bits to stay stable during engraving, ensuring accurate and precise results. With their sharp cutting edge, milling groove and clean surface, these tool sets work quickly and cleanly, leaving no glitches or scrap behind. The drill bits are packaged in a high quality plastic box, which makes them easy to carry and provides better protection, preventing any damage to the blade tips during delivery. The set includes 5 boxes, with each box containing 10 different drill bit sizes: 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, and 1.2mm. Each box contains 5 pieces of each size, providing a variety of sizes to meet different drilling needs. Please note the following: 1) PCB drill bits with a diameter below 0.5mm are delicate and prone to breaking, so it is recommended to handle them with care during use. 2) Avoid using these drill bits on hard materials, such as high hardness iron. 3) Ensure that force is applied evenly and vertically while using the drill bits, and avoid touching the blade with your hands or applying external force to prevent damage. This PCB Drill Bit Set comes with a 180 days warranty. If you are not satisfied with our products, please feel free to contact us for a replacement or refund. The PCB Drill Bits may also be referred to as micro drill bits, NCN drill bits, micro drill bits set, plexiglass drill bit set, circuit board drill bits, PCB drill set, drill bits for dremel tool, small diameter drill bits, or PCB drill bit set.
