You can work with even smaller bits, but finding a chuck that can hold a > #80 drill, without running 2x the drills size in runout is something > I've yet to find. :(
You know about these? Very small solid carbide bits with 1/8th inch shanks. These are not expensive (if you shop around). They are typically sold mounted in a block that holds 50 bits. The block fits in some automated bit changer. In industry the bits are re-sharpened a few times. Buying the resharpend ones costs less, about $20 for a block of 50 used/resharpened bits These bits even work in a $75 Harbor Freight drill press a couple times without breaking, https://www.adafruit.com/products/2118 http://www.ebay.com/itm/Lot-of-50-Resharpened <http://www.ebay.com/itm/Lot-of-50-Resharpened-Micro-Carbide-PCB-Drill-Bits-0320-67-/172061731231> -- Chris Albertson Redondo Beach, California ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
