Hi People.

My first attempt at using the DBS22.

As you can see I'm not using a Tormek wet grinder, this set up works really well and the CBN wheels are a joy to use.

I am loving the drill sharpener it is a fantastic bit of kit. Does anyone know what the lines are for, marked in red please?

Thanks

It was a 10mm drill I sharpened.

Page 13 of the manual discusses this as shown in the excerpt below.

Dave, welcome to the forum and thanks for posting your first results. :)

What grit do you use for drill bit sharpening?
Do you hone the drill bit after the sharpening?

This is a very interesting use of the BGM-100. What grit of grinding wheel you using? The only draw back I can think of at the present would be the metal particles from grinding, could possibly get into the slide area of the DBS-22.

I believe there is an area of potential that can be possibly harnessed beyond Tormek's stated use of the BGM-100.

Jan and Elden..

I'm using a standard grit and extra fine grit on the wheels. Here is a small vid I did and there is a link to where I bought the wheels from.

I have some diamond hone files but haven't had to use them yet. I use the fine grit wheel to grind with.

Thanks for the link! :)

Your extra fine CBN wheel should correspond to some 360 grit of conventional abrasive.

Ground a 9.5 mm cobalt drill to 135 deg + 7 deg primary and 20 deg secondary.

Went through 6mm alloy angle like it was plastic. No pilot hole just a centre punch and some cutting oil.

Well done, Dave, congrats! :)

You have produced very nice conical spiral chips. This happens when the feed rate is small and the material is ductile. ;)
