FAQ
We use nano-grade substrates, which increase bending strength by 20%. As long as the parameters are matched, the lifespan is very stable, effectively reducing downtime.
No. The chip removal groove is mirror-polished and extremely smooth, allowing chips to be discharged smoothly.
Strictly controlled within 0.003mm with this range, ensure precise hole diameter and avoid enlarging the hole.
Yes. We have a specialized series of nano-coatings that are high-temperature resistant, wear-resistant, and specifically designed for difficult-to-process materials.
Standard sizes are readily available and can be shipped on the same day; custom-made items can be delivered in as little as 7-10 days.

MSU have rich stock for standard micro drills, if have stock, we can ship to you within 3 days. please download our 2026 Micro drills catalogue for speficiation of micro drills.

Every single item has batch traceability. If there’s a quality issue, we respond within 24 hours and offer refund or replacement.

“Our micro drill bit diameter tolerance is strictly controlled within ±0.002mm , and the shank diameter tolerance is h6 standard. Regarding runout, each batch undergoes high-magnification optical inspection before leaving the factory to ensure that the runout is controlled within 0.005mm , minimizing the risk of drill breakage and ensuring the consistency of hole diameter.”

“We offer a variety of coatings, including TiAlN (TiAlN) and DLC (Diamond-like Carbon). To address chip removal challenges, our micro-drills feature mirror-polished chip evacuation grooves . This significantly reduces cutting resistance and prevents built-up edge (BUE) formation, making them particularly suitable for deep hole machining.”

“While our unit price may be slightly higher than that of lower-end brands, by increasing tool life by 30% and reducing scrap rate by 0.5% , your ‘overall machining cost per hole’ is actually lower. For customers with high annual usage, we offer tiered pricing and annual rebate agreements.”

Yes, we can produce as per client’s drawing or request, then our engineer will make drawing for confirmation, we will produce samples for testing after client’s confim.  MSU Provide High-precision machining solutions, improved micro-hole machining yield. wholesale micro-drills, reduced tooling costs.

Yes, our MSU426 series is suitable for stainless steel.
