Drill sharpening

[Ray LyonsParticipant @raylyons29267]

Called at LiDL this morning and saw another drill sharpening device. I have a couple of similar devices whick are of little use. Anyone had any thoughts about this new offering.
Don’t want another useless bit if kit taking up space under the bench but very tempted since my Lidl is only across the road.

LiDL tooling stuff tends to be either total crap or pretty decent and excellent value for money. That said I'd pass on the drill sharpener as even the, allegedly, better ones working on this or similar principles such as the Drill Doctor are known to be a bit on the hit and miss side. Never seen any of the cheap plastic ones actually work as intended in pencil sharpener "just shove it in mode". That said its pretty rare to find apencil sharpener that works just like that too!

If you are going to accept a bit of fiddling then far better to use something that allows you to see whats going on. I have one of the old style Plasplugs sharpener sets. The drill dooby works quite well once you get the knack. Also use a Picador swing across the grinding wheel device but again that needs a knack and, as noted in a previous thread many of the similar devices on the market are geometrically unsound.

Be interesting to see how the 4 facet sharpener articles currently running in MEW pan out. I have my own ideas on how to do this properly with particular attention to dealing with the drill angle and grind cut setting weakeness that seems endemic to all drill sharpening devices.

I bought one of these some years ago ( and had forgotten that I had it!)

It takes drills from 3mm to 10mm BUT in 0.5mm steps. My drills are in 0.1 mm steps!

My assessment is that for (hopefully precision) use in a Model Engineer's workshop – not very good. For general DIY type use it's OK but, there again, folk reading stuff here will likely have an offhand grinder and, for DIY work, that should be sufficient.

learn to grind your drill by hand. It takes a bit of time, but its worth it. Little ones are a bit tricky

Thanks for the comments. Did not go over again so was not tempted. Saw a demo on You Tube for hand sharpening drills. Looks easy and with practice could well be the best way to go. Thanks to all for your replies.
