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" :)
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).
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.
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
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.
