20pcs Micro PCB Drill Bits Tungsten Steel Bits for CNC Engraving Printed Circuit Board 1.65mm-3.175mm(2.75mm)

Micro PCB drill bits are specifically designed for precision drilling. The Tungsten material features high hardness, high strength, heat resistance, wear resistance, deformation resistance, and long-lasting performance.With their precision-ground tips and enhanced rigidity, they ensure optimal hole quality, thereby enhancing the overall performance and reliability of the PCB. The meticulous symmetry of these edges is great for promoting cutting actions and avoiding any lateral displacement during the drilling process.Tungsten steel Carbide drill bit set is designed for PCB, CNC engraving and other high-precision hole required equipment, suitable for electronic boards, SMT, amber, hardware and other precision parts of the drilling process.Precise alignment is critical. Use accurate guiding systems or fixtures to maintain straight drilling and prevent walking.Apply lubricant, such as cutting oil or coolant, especially when drilling metal. This reduces friction, heat, and prolongs the bit's life.Model Number : Micro PCB Drill BitsDIY Supplies : MetalworkingMaterial : Tungsten CarbideType : Twist Drill BitUse : PCB DrillingRandom color
