Drill Bit Sharpener

Post by richardpope50 » Fri Jun 21, 2019 6:09 pm

As title. Any recomendations?

I've got a hand held one and a cam type that fits a drill for power and both, quite framkly useless.

The big ones all seem equal to the cam type ones I have albeit in one unit so not sure how good they really are. Drill Doctor 750X seems a good one but at the end of the bday is still a cam type device like my drill based one.

I've sharpened a couple of 13mm drills by eye on a bench grinder with surprising results - luck?

I also want to go up to 13mm / 1/2".

I want a good one that works as well!

Used to have one made of plastic that held a drill in place and then you rolled it back and forward over sandpaper. It had offset wheels that made it get the right angles. Then stop rotate and do the other side.
Loved it but sort in a move.

Was brilliant and consistent

I cannot even find a picture of one on google

A mate of mine is an aircraft sheetmetal/structures mechanic and he has a dedicated grinder with a stop to set the corrcet point angle, and then he does the land clearances by hand. Most of his stuff is 3/32'' to 3/8'' maximum.

Something I'd like too. Have found the all in one type can work OK on larger drills - but still need skill, but useless on small drills. And of course larger drills are the easiest to do on a bench grinder.

I afraid that is the one I find useless as well as a plastic housing and a cam mechanism one.

Agree with Dave too.

So it seems the Drill Doctor 750X is the one to get albeit very expensive. At about £20 per set of new bits, it is still worth paying for a Drill Doctor instead of buying new sets each time.
