This 10-piece set of carbide PCB drill bits is engineered for high-drilling across a wide range of materials, including acrylic boards, wood, PVC, aluminum, and circuit boards. Manufactured with premium carbide material and advanced grinding technology, each bit offers a cutting edge that minimizes cutting resistance and reduces breakage, resulting in smoother and cleaner hole walls. The enlarged waste discharge improves debris removal during operation, helping to maintain consistent drilling performance. Each bit features a calibration ring for improved alignment, stability, and work efficiency, especially important in high-tasks such as PCB board fabrication and part assembly. Under normal working conditions, each drill bit can handle 2000-5000 drilling operations and is regrindable 4–5 times, delivering exceptional lifespan and cost-efficiency for hobbyists and professionals alike.

Details:

*Drilling rig waste discharging space is large, resistance is small, and debris discharging is stable.
*Use high-quality materials and fine grinding technology to make the cutting edge er, reduce cutting force and drill breakage, and improve the quality of hole wall.
*Design of calibration for ring to improve work efficiency
*Strictly avoid local holes and for ensure the quality of trimming.
*Long service life, 2000-5000 drills can be drilled under normal working conditions, and 4-5 times can be regrinded.
*It is suitable for drilling of acrylic board, wood board, PVC board, circuit board, aluminium board and other materials.
