I used my set the other day for the first time I used the 6M-100 for a set screw in a door knob I used a regular drill bit then my harbor freight drill and tap bit and I used it in my dewalt XR impact driver in the 1 then 2 speed settings and they worked perfectly fine. I'll be getting more, I used them for 8 door knobs and is still very sharp.
Great video. Reviews of both HF and Dewalt show a lot of people snap these. I want to learn the technique before I snap mine. Material thickness, plumbness of the drill, manually remove the bit. All good points.
If there is an existing M3 hole and you want to retap it to an M4 in ALU. Wouldnt you want to use a very slow speed with a drill press due to the tiny 0.7 pitch? Perhaps its best just to use a regular bit and create the hole then hand tapping it but I dont have. 3.3mm bit for the minor diameter.
Also some people use these to put threads in hardwood, very quick and convenient way of cheaply fixing things as long as you are "very" careful not to put sideways stress on the bits and break them. Then it starts getting time consuming and more expensive.
I have wondered how well the concept would work. My drills are variable speed, so I should be able to get a sweet spot. The hand removal tip is great also. I am looking tapping wood also, and these may be a way to give that a spin.
I assume the extra bits were included since why waste half of a clam shell case...? The sales guys said add some cheap bits and we can charge more. Plus, now you can add the DeWalt bits. Yes, cutting oil would have helped.
I would also like someone to try nail punch drilling in soft sheet material like aluminium and copper etc and then tapping it. Large manufacturers use friction drilling so that there is more material for the threads in the thin sheet at the hole.
That case doesn't hold the bits in very well. Every time I opened the case all the bits were just flopping around in there, I keep it in my tool bag "electrician". Eventually the case cracked apart. The key to using these is keep it straight, if you put any sideways force on the bit "SNAP" especially the smaller bits. I think they are worth the money, A good buy. I bought for 12.99
Yes a lot of times you'll get away with just running the drill backwards and then they'll be that time when you really need the threads and it will cross thread and blow them out
Nice video, you need to do more demonstrations of how the tools perform. It would probably be easier to use the quick connect bit supplied with the tool for faster removal from the work piece.
Yes I'm working on improving demonstrations of tools and will do more of that as I get into accessories I'll have to demonstrate them just to show how they perform
Cactus, im trying to fix a stripped thread in a car’s subframe. Its for the sway bar mounting bracket. My cordless drill jams upon initial try. Is the drill underpowered? Would you recommend the HF for this one time fix? Thanks
My guess is it will be tough to drill the old threads out, depends on how they made them, the insert I'm thinking about is it's like a large rivet that has threads on the inside, a helicoil might work as well
This will drill a truck chassis very well an more I have taped 14mm over an over an over you need to have more experience on how to do this and to remove a snapped one you need to remove with a needle nose or punch it will snap Easter then drilling it out 👍

Thank you. This is how a review should be done!

Enjoyed every minute of your videos man.The demo was spot on.Thanks again man.
Thank you
Thanks for including all the tips about using tap drill sets, very important details to know and helps noobs like me 😅

Nice video... I happen to have the HF and the Dewalt sets... they both work quite well !!
Have used the harbor freight version in an m12 impact driver to to make threaded holes in 4 sqaure covers worked fine. Was the 6-32 believe it or not.
Thanks for the review of those bits. They seem like they are fine for light gauge mild steel. That was a good idea backing it out by hand.
Thanks
Good tips. I'm going to purchase a set.
The high end brands like wera include the bits too only difference is with the wera the taps fit into the bitholder for an impact driver

Been looking for these. Didn’t realize freight had them 👍

My drills are variable speed, so I should be able to get a sweet spot.
The hand removal tip is great also. I am looking tapping wood also, and these may be a way to give that a spin.
They'll probably work pretty well in wood
THANK YOU,GREAT VIDEO 🎉

Did the DeWalts fit in the HF case? That would be cool if they do.
Yes they did

Hello sir. There is a thing called a thread insert, you would still have to drill the right size hole
Martin Schaffmeir yes im actually trying to use helicoil but i cant drill the existing hole.
@@bhadz100 try a Milwaukee 1/2 magnum holeshooter, I'd lone you mine, or see if you can rent one

Martin Schaffmeir i think ive seen that threaded rivets. I guess ill just have a threaded stud welded on
Always use oil or coolant, you get a cleaner cut.
Thanks graat video

I might be wrong. greenlee had them first. I bought a set 5 years ago.
That is entirely possible these type of tools are right up Greenlees alley
Good post cat, thanks
Thank you
Very good how get in uae
Only 12 more till that toolbox tour!

The chamfer is the debur...
I find out by trial and error that they will break when you done and back out. DONT PUT THEM BACK IN. They more likely will break

That is my biggest issue, I want metric drills. Why does nobody carry just metric drills? They are nowhere, and metric is much better than SAE.
Yes I run into that myself any time I've needed a specific metric drill I've always had to order it.
