PD30A, 1/8" Shank, PCB Drill Bits Set, 0.1mm-3.0mm, 30pcs

These require an adapter if you use a mini drill with a 3/32” shank. Smaller sized bits were very prone to break, requires steady and careful hand or a press with significant clearance. Assortment is excellent and has great utility, but sizes are not marked on the bits, which is inconvenient.

Nice bits for drilling pcb

Work like they should

I used the .9mm bit to drill holes in a PCB I routed on my 3018-PROVer. The Bit worked perfectly, no issues.
