- So the short review is that I don't recommend them. They do work just the quality isn't there. maybe if they were a little sharper. The idea is cool but the quality just isn't. Want to buy a set yourself and try them out? I found a link on amazon: amzn.to/3dg5x10
I recommend just getting a good tap and die set like this one: amzn.to/3lXGrYR
Have you tried these drill bits before? let me know if you have in the comments below. I would love to know if you had them work better for you.

They are not high speed drill bits! I bought some at Home Depot and they work great! Use low speed with pressure and cutting oil it will work like it’s suppose too!
I tried slow speed as well. I think these are just junk. The video I watched on them they made it through easily
Drilled a pilot hole hole slice! Low rpms more downward pressure and lot of cutting oil. 💪 It looks like they held up to your torture test 🤣 lol
Thanks for the review. I often wondered about those.
Maybe there are some good ones out there but these are junk
Excellent, thank you for testing these.
Thanks for watching the video
less speed more pressure bud, its a hard lesson to learn but im having good luck with that keeping bits alive
I tried different speeds and pressures. I think these are just junk bits
If you pre drill with a combination center drill it will work better. And cutting oil helps tool life. Chainsaw bar and chain oil works surprisingly well.
Yeah but the whole gimmick of these was you didn’t need to you could just dive in with them and be good. One of those too good to be true
You should know who you can ask drilling,machining,and welding questions 😉
@@alanrawson-wg8io I say you know a thing or two 😆
They’re made for aluminum dense plastic and mild steel. The center drill lets the drill bit start cutting on the bit’s edge instead of the point.
Lol, are they possibly for drilling out messed up thread holes to the next size up and adding new threads? That way you dont drill a pilot hole, the holes already there and your just cutting the threads off with the bit.
I don't think so... from what I have seen and the videos I have watched on it they drill new holes with these bits
Pilot hole, slow and steady. Once it starts to bite, then pull out, use spray then back in and they work as they should. It's a process 👍
Yeah but these are advertised to just drill right in
I ain't never seen anyone that knows how, try to send a large bit thru thick steel before, those that know always drill a smaller pilot hole don't they? At first I just assumed that you didn't really know what you were doing, until you decided to do the pilot hole, & "look what a small good bit can do", like nobody ever just does that... From then on it just seemed like a product test set-up for failure, unfortunately.
Honestly I was trying to test them how they showed with no pre drilling and just sending them home. I realize this isn’t the best way to do it but they show it being done.
They're actually meant for impact driver. There's a whole equation too as far as drill speed & material you're drilling/tapping. The main thing is backing it out...folks tend to full send reverse & it ends up getting cross threaded. The cheap ones that you'd find on Amazon tend to be junk but the more premium brands seem to work much better.
Ahh I did not know they were meant for impact drivers. The videos I have seen they just use a drill
@@TheBeardedJeeper Check out mine, be happy to send you some to try out, with an impact. Just google Holemaker Technology.
Excessive pressure generates excessive heat and wear, let the tool do its work.
I wasn’t pushing a lot at first. No matter how light or slow these did not want to grab
Awesome Great Review!👍🏾🫵🏾😉
Thank you!
Those bits work great but,
you destroyed the bit by not using cutting paste or oil and you need to drill slower. Get a HSS cobolt from a known reputable brand.
They come from the Main Land of Communism....😂😂😂
Haha yes they do
You are struggling with the basics. Good luck.
Bro ive never actually drilled before and even i thought this lmao
I was testing how these were advertised to work. Any other time I would go slow drill a pilot hole and use cutting fluid
