I've got a clone of this machine from Vevor and found this video because I'm looking for a way to grind left hand drills. It's really great for regular drills. The issue with not tight collet in 4:28 was because You've assembled the holder improperly. There is a small lip in the part with male thread and You're supposed to put in collet in that part first so the groove on collet is grabbed by the lip. Then everything tightens beautifully with a slight "snap" :)
Great observation, @azizinojatov1157, and you're exactly correct -- normally. 🙂 If you go to 2.33 into the video, you'll see that this drill sharpener uses the ER Collets backwards, so they don't snap into the nut like they do in ER Collet Chuck nuts. Thank you for bring that up though. Maybe I should have mentioned that more clearly when we shot the video.
Incorrect, if you look at the nut it has a provision to snap the collet in place via a lip quarter way around the diameter. This in turn ensures that the collet seats against the internal bearing and also releases the drill bit when finished. No need to hit the nut on the bench which is probably not good practice
you are so wrong listen to what people are trying to tell you . pretty sad when the tool company is totally wrong on a machine that is 3x the cost of a vevor
So very true, David. If we included prioces on every product in every video, we'd never be able to keep up with price changes, sales, and discounts. There's a link in the discription that will take you to the website that includes current pricing.
This is a fantastic video! I have a DBG13D myself for our shop and its great and super easy to use once you learn how to properly set the tip just right (which I admittedly have issues doing, which is why I came to this video).
Sorry for the long delay, @salaamkeneth8809. Yes. Start the video at 5.38 minutes in, and you'll see how to adjust the angle. Since 90° is flat, to grind a 10° angle you'll need to set it at 100° (90° + 10° = 100°). There's no mark for 100°, so if you need it to be exact, you might need to use a protractor.

These are made by MRCM , and are re -badged by many vendors, including this one.
OMG. Wrong assembly of collet block. If you are familiar with er collets, the have to be put in the nut first!!!

@@aimcnc3830, yes, you're correct -- for a collet chuck. These machines are made differently, and the collets are inserted upside down.
@@wonbythe1 Look at the nut, it says in instruction manual to angle the collet into the nut to seat it.

A price would help?

Me too! This is exactly the video I needed. Very helpful. The DBG13D has a spot on my workbench!
So glad this helped!
can it also sharpen 3.175 mm 10degrees 0.1 engraving carbide bits

Haven't found à grinder that can sharpen as good as I can by hand
