These drill bits are crafted with precision machining using high accurate equipment, ensuring good milling and cutting performance. With high hardness, wear resistance, and anti-bending properties, they provide sharp cutting edges that reduce cutting force and enhance the quality of the hole wall. The symmetrical cutting blades help to achieve highly effective cutting, minimizing drilling offset and ensuring precise results. Suitable for a variety of materials, including PCB, FR-4, CEM-3 boards, carbon fiber, and more, these drill bits are ideal for precise hardware processing and circuit board applications. Product Features: High-precision machining for accurate drilling High milling and cutting performance for increased efficiency High hardness and wear resistance, reducing the risk of bending Sharp cutting edge for reduced cutting force and improved hole quality Symmetrical cutting blade for effective cutting and minimal drilling offset Product Specifications: Type PCB Drill Bit Quantity 50/td> Shank 3.175mm (1/8'') Material Carbide Size 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm (5PCS each size) Package Includes: 50 PCS PCB DRILL BITS SET ⚠️ WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. www.p65warnings.ca.gov.
