This question came up recently and we thought it made perfect sense. The Lil Bit Drill Sharpener is perfectly suited for any manually-operated, single spindle graphic arts paper drill (hand lever or foot operated that is not hydraulically-driven.) It simply positions under your drill bit and while on and spinning, you lightly touch the bit to the sharpener. To see the Lil Bit Sharpener in action, watch the video linked below and skip to 58 seconds in.
As far as which sizes this sharpener works with: we have tested it as being able to accommodate drill bit diameters as small as 1/8″ up to 1/2″ with no problems whatsoever.
