50pcs Carbide Micro Drill Bits 0.5-0.9mm | High Hardness PCB Drill Bits for Circuit Board/SMT/Form | Sturdy & Balanced Cutting Tip | 5 Sizes in Plastic Case

Produktbeschreibung

Carbide Material - Micro drill bits made of extra-hard tungsten carbide last 3X longer than standard bits. Suitable for high-frequency PCB drilling without bending or breaking. Accurate Cutting Performance - Sharper cutting tips reduce friction by 40% compared to conventional bits, creating cleaner holes for circuit boards and electronic components. Engineered Symmetry - Strictly balanced cutting tips ensure drilling exactness within 0.01mm tolerance, minimizing deviation during PCB fabrication and SMT assembly. Multi-Industry Use - Industrial-grade drill bits handle diverse materials including fiberglass boards, aluminum substrates, and plastic forms for electronics/hardware manufacturing. Complete Size Kit - Includes 10 pieces each of 0.5mm/0.6mm/0.7mm/0.8mm/0.9mm bits in organized plastic case, covering all PCB prototyping and repair needs.
