Those drill bit sharpening machines…

I think my For very small drill bits I have a Wishbone Drill Sharpener

Great for big drills like the taper shank one shown, but not much good for small sizes. For the latter from about 4mm down I just buy enough to treat them as disposeable. A set like this is a handy thing to have. Titanium Coated HSS Drill Bit Set 99pcs Piece Case Plastic Wood Metal Kit | eBay

The Reliance Drill Grinding Jig shown in my post #14 was manufactured in three sizes;

No. 1 Capacity 1/16" to 1/2" No.2 Capacity 1/4" to 1" No. 3 Capacity 1/4" to 2"

Mine is the smaller model: 1/16" to 1/2".

You can sharpen even smaller drills if they are held in a pin chuck.



For anything very small, I have a Wishbone Sharpener which is quick and easy to use:

You can buy a tool that holds the chisels and plane irons at the correct grinding and honing angle for sharpening on the oilstone. I can't remember how I came across mine, but I have it at least 25 years, so it's definitely pre-Lidl.
I did buy a drill sharpener from Lidl when they first appeared, but I haven't got around to using it yet, as it's far easier to just buy new drill bits than to find time to start sharpening the blunt ones

I was boring some particularly tough S/S on the lathe the other day. I had to re-sharpen the bit several times, plus adjusting the rotating speed and using extra lube and pressure. Would have cost a fortune in drill bits could I not sharpen them in a few seconds.

I bought a few kilo's of drill bits from an engineering company that was closing down years ago. Apart from a couple of bargain buys I have not bought a bit for ages.

Might be in your area soon - fancy a beer?

Has anyone tried spinning a broken bit in a hand held drill chuck against an angle grinder to set the broken bit angles equal before shaping and sharpening the edge?

I've done lots of dodgy things in my workshop: why do you ask?

These days though I'd use goggles and wear proper footwear (I'm not completely stupid)

No, because I have a bench grinder that I would use for that purpose.

Bench grinder in the w/shop, angle grinder with a flap disc when away. Bought a Lidl one for the small sizes, but first try wasn't promising.

For wood tool edges, I use a japanese water stone and an Axminster angle guide.

I have for years sharpened drill bits, chisels and plane irons by hand on a bench grinder or a set of waterstones touching them up with a diamond lap that has been handed down to me via several generations. However I am now the possessor of a Tormek and bought several jigs to aid in its use although I baulked at the €280 for the drill sharpening one.

Over on another site, they swear by the 'Drill Doctor' sounds a bit cheaper than the Tormec + attachment. No personal experience.

OK, angle / bench

I have a bench stand for my angle grinder, so not as dodgy as it sounds
The Why was in the Question.

I bought the Tormek to sharpen the turning tools I have just bought to accompany the new lathe, never sharpened anything like them before and jigs seem to be the recommended way so went the whole hog. It will make sharpening chisels and plane irons very quick as well so I am likely to do it more often.
