Thats cool looking that drill its like a step drill on the tip.
G'day Kevin from Australia.
Allways good to see your videos.
Look like good drills.
I find living down here the only trouble with banggood is the 8 week wait. ✌
That's about what it took here in the US!
absolutely love your room
Hi Dave ... I have watched many of your video's. whether you have been machining or testing / checking products out. Even how Meticulous you have been in everything you do, Especially when you went through the Drill Bit sharpening Saga. for you to even recommend these Drill bits, and watching, how they drill through the samples you showed, it shows how good they are. Thanks again Dave, keep up you great work. LOL on a Brighter note, I am going to look forward to see how you are going to sharpen them one day. :)
You sound like mr Mackey “mkaaaay”
Awesome Dave, thank you
Thanks Dave,
If u drill stainless use plain old water to lubricate it or if you can use a hand drill and submerge your part in water. Don't believe me ! Try it on a scrap piece of stainless first
Great input!
Nachi is my favorite brand if drill bits to use.
Never heard of them...
Very interesting design and it is nice that it cuts so well. My only question is how do you sharpen it when it gets dull?
LOL for $9 just buy another set....
@@TheMiniMachineShop some one must know how to sharpen them as the original
I did purchase a set of these awhile ago and yes, they do cut extremely well. Funny thing, when I switch from US to Canada, price quadruples. Still good value for the money tho.
That's strange wonder if its a bug in the web site...
Thanks for the video. How have the bits lasted so far? Would you compare them favourably to, for example, Bosch's Cobalt M35 or M42 bits, in terms of quality?
Sorry but I've only used them twice on ss. So can't really say...
👍
Thanks for sharing
I bought a set of these, and they are as good as you find them. But the big problem I can see coming up will be the first time I need to sharpen one. Any thoughts on how that may be possible?
Yeah good luck on that one! They are so cheap I wouldn't even bother...
And if you reduce the speed, add a lil bit more pressure, and with some lubricant, that would be great 👍.
Do You remember the link?
i never order from Banggood i live in USA, i wonder how good and how long it would take to get here
I order from them all the time I'm also in the US and it takes about 2 to 3 weeks. I've reviewed a number of their items causing complete sell outs. I'll never share it if it's junk.
How do I drill D2 steel up to 20mm HRC 60
Good question these are cobalt though..
But how long does these bits hold up over time?
So far I haven't worn one out yet and I know many have bought them. Their cobalt!
You do not have a shop, it is more like a surgical salon. If I could find an employee who was that organized, I would probably be forced to not let him know who he is working for.
LOL
That package with the pin is designed to stop people opening the pack and stealing drills, when it's on display in a retail store. ;)
That makes sense! Never saw packaging like that here including drill bits at HF...
That's some Chinese patent I guess. Bought a set of taps and corresponding drillbits some time ago here in Sweden.
Chinese I guess. It took some time to find out the opening procedure. Grab the bottom and lift by the handle!
At least no item is escaping the thin Chinaplastic bag during transport. Lost a hole set of ER32 collets and received an empty bag.
Missed clicking "Show more"....
Get some coffee man and wake up!!!!
"i have no idea how to make you guys see it"
- easy, dont film with potato. 720p was outdated in 2010
All 300 of my videos are recorded in 1080p CZcams downgrades them to 1920 where you get 720p is a mystery. And was outdated in 1998 by Television not 2010.
