0.05mm? sa standard drill bit sizes, N * 0.1mm ang meron starting from 0.2mm. halos kasing-nipis na ng buhok ang 0.05mm (50um, 60 to 120um ang buhok).

hindi drill bit ginagamit kung PCB milling. end mill gamit. madalas 60 degree end mill para 'yung dulo pwedeng mag-start at virtually 0 mils, then dependent sa depth kung gaano kalapad 'yung mami-mill.
