AI Server PCB Drill Bits Emerge as Hidden Supply Chain Bottleneck
tengyanAI · x · 2026-09-03
Tessara Research's Chokepoint newsletter traces an overlooked consumable in the AI supply chain: PCB micro-drill bits.
- AI server boards are thicker, denser and harder to drill; advanced boards need tens of thousands of holes, with deep holes still mechanically CNC-drilled rather than lasered
- Tungsten-carbide bit life is shrinking—sometimes only a few hundred hits—so drill demand grows faster than PCB volumes themselves
- High-end drill makers Topoint and Union Tool are seeing accelerating revenue, expanding margins and capacity additions, but the open question is whether drill consumption keeps absorbing new capacity
The authors argue the chokepoint is tightening but not yet blocking PCB production.
