FAQ's of THR SM 2.2x0.45*D4:
Q: How should I use the THR SM 2.2x0.45*D4 micro drill bit for PCB drilling?
A: The THR SM 2.2x0.45*D4 is optimized for through-hole drilling in printed circuit boards (PCBs) using CNC machines. Ensure correct alignment on your PCB drilling machine, maintain spindle speeds between 5,000-30,000 RPM, and choose either dry or mist coolant modes for efficient chip evacuation and temperature control.
Q: What benefits does the TiN coating provide for this micro drill bit?
A: Titanium Nitride (TiN) coating significantly enhances surface hardness, heat resistance, and wear resistance, extending the bit's service life. This provides superior durability and consistent cutting accuracy, even during high-speed and high-temperature operations in electronics manufacturing.
Q: When is it necessary to replace these micro drill bits?
A: Replace the bits when you notice a decrease in drilling efficiency, visible wear on the cutting edge, or a decline in hole quality. Although designed for longevity, the THR SM 2.2x0.45*D4 is not resharpenable. Proactive replacement ensures continuous precision during fine drilling tasks.
Q: Where can I use this drill bit besides PCBs?
A: Apart from PCB and SMT stencil drilling, this micro drill is suitable for applications in the electronics industry requiring high-precision holes, such as in micro components, sensors, or connector plates where fine and clean holes are essential.
Q: What is the minimum order quantity and how are the drill bits packaged?
A: Each order of the THR SM 2.2x0.45*D4 micro drill requires a minimum purchase of 10 pieces. The bits are safely packed in sturdy plastic boxes, ensuring protection from damage during transit and storage.
Q: How does the drill bit maintain precision during extended operations?
A: Thanks to its solid carbide construction, high HRA hardness, and double flute design, the bit retains cutting stability and accuracy for prolonged periods. The TiN coating also minimizes wear and reduces the impact of heat, allowing for sustained high-precision drilling.
