Bought a HF 61778 drill bit sharpener today. My drill bit sharpening skills are hit and miss - sometimes they'll make a hole and sometimes not so I decided to pull the trigger - at $35 I figured it was worth a shot and I could take it back if it didn't meet my expectations.
Bottom line - it works! It doesn't leave a pretty, shiny face like a new bit would have but it leaves a serviceable bit. The down sides - 1) mine came with no instructions but I found them online and 2) It takes some fiddling to get the center of the sharpened area in the middle of the bit, a skill that can be learned. Plus sides - 1) the sharpened bits make a nice curl in steel (didn't try aluminum or stainless) and 2) even though it doesn't say so on the box it will sharpen 1/8 bits using the smallest hole.
This unit sharpens from 1/8 to 3/8 or maybe a tad more - the big hole is marked 10mm. I wish it went up to 1/2 " (13mm) but for the price it's worth it.
