Thank you for making this video! I’m about to attempt my first repair of this kind and I had a lot of questions about the sizing that no one seems to talk about. This video helped me a lot.
Thank you for this explanation. Your video is a time saver. I am about to try and repair a steel bike pedal and its aluminum crank. Your video with how to figure out the actual tap size was helpful so I did not have to buy all the extra parts.
This video needed to exist when I was doing my front brake calipers 3 years ago. Amazing work, good that you showed how the helicoil went in the wrong way and did not work. Most people don't post videos of when things go wrong. 10/10 all around.
Did you mean the tang knockoff tool he tried from inside first? That is the correct way to use the tool but no it didn't work at first without bending it back from the other side.
This is perfect! May I suggest that you up load the exact same video with a new title?? [so your video is more easily found] “ helicoil install without the kit” I’m betting more will find your video this way
Thank you for this video , I'm now coming to a realization that all these coil brands and even after market coil brands are screwing with the size and it can get really frustrating, the Amazon kits are 2 sizes up same thread pitch but these helicoil guys I'm guessing really use oversize taps , they also sell kits without bits but only a tap , their "special tap
I took from this vid that for his M10x1.5 bolt hole he could have just used an M12x1.5 tap he already had so 2 mm up in size using the same 1.5 pitch. I may try doing the same per my above comment but for my M10x1.25 thread repairs I'd use an M12x1.25 tap for the insert to thread into. I guess that counts as 'oversize tap' since its M12x1.25 vs M10x1.25 original hole.
Hi, nice video ... I wanted to ask you if after installing the brake caliper, the helicoil holds well or you had problems, because I would like to do the same thing, thanks
so i have a m11 1.5d helicoil, problem is i cannot find a m13 1.5 d tap in any of the sets i find it seems this one is skipped, is this a time when standard and metric meet, or is this just a very uncommon size of tap, could i use a standard size tap with the same D, im going to also mock up a few holes in some plate steel and i will share the results.
@@cruizinmax4017 turns out is is 2 sizes up so a m13 1.5 will work, it is a speciallty tap though as its used for fixing m12 oilpan plugs to tap one size higher and use a m13 plug. every tap and die set i have seen in canada does not include a m13 1.5 tap. it seems odd number metric taps are usually left out so it would be an inconvienient special order in this case. hope this saves someone some time figuring this out.
If you want to use a helicoil thats for an original M8 thread hole then you would use an M10, the taps that come in the sets that you buy for lets say an M8 will be labeled M8 instead of M10.
@@cruizinmax4017 thanks for the reply. I want to make a aluminum build plate for my CNC that has an array of M8 threaded holes, but I want to reinforce these with helicoils so that they don’t wear out over time. If I understand you correctly, I would have to make the holes and threads in the aluminum plate in M10 to fit the M8 helicoil? Thanks for your help!
So u know when u shop for the heli coil kit for a certain bolt size, like an M12 or M14 for example, that kit will tell you what size drill bit you need then just measure yours if you got a set.
Just curious, but why work on metric materials and use metric references, but then measure everything in SAE? Made me laugh. Love the methodical approach, and host commentary. Quite good.
I cannot believe this instructional video uses imperial to measure metric taps whilst also rounding when attempting to determine the special tap size measurements. VCoil Taps are 0.3mm bigger than standard eg 14.3mm 1.5 for an M14 1.5 bolt typical labelled SP14.3 1.5. Use a kit to get the correct tap. A standard tap cannot be used for helicoils or VCoils shown in this video. The video goes on to measuring the coil but these stretch cut to fit into a fresh tap. Also reverted to using helicoils rather than Vcoils: best to stick to one manufacturer's products... Just buy a $15 full kit and be happy that a repair is so easily possible. Thread stripped bolts shouldn't be re-used: no one should let this guy anywhere near their vehicle.
I know...so unbelievable but true and I admit my mistake, force of habit I suppose but as far as the rest of the comment I have done about 10 more repairs like this so far, one of them on a cylinder head without buying special taps or bits and so far so good, no issues or complaints. Oh yea, one of those cars gets abused on a race track, omg!

Just the information I was looking for. Thank you 👍

Thanks for the heads up on taps and drill sizes good video thanks again
Tap Magic actually works, at least in my shop, saves my bits and stuff. Thanks for showing the process you used!
cool, this is what i was looking for

Ty so much for ur video no where does anyone say what size measuring is best way
Hi, nice video ... I wanted to ask you if after installing the brake caliper, the helicoil holds well or you had problems, because I would like to do the same thing, thanks
it holds very well, i take this thing to the track.
Thanks, Because I would like to fit Brembo calipers on the S2000 but they have an M14 ear and I would like to use Helicoil to reduce the size to M12.
I wonder if stick to 2 sizes up no matter what thread size tap you go for. For example. M6 tap for and m4 repair?
Most companies yes, but just get a set of taps from amazon, I paid $100 for a decent set.
so i have a m11 1.5d helicoil, problem is i cannot find a m13 1.5 d tap in any of the sets i find it seems this one is skipped, is this a time when standard and metric meet, or is this just a very uncommon size of tap, could i use a standard size tap with the same D, im going to also mock up a few holes in some plate steel and i will share the results.
Ure on your own on this one, should be just 2 sizes up...

Wait, I’m so confused. If I wanted to use a M8 helicoil, what size drill and tap do I need? Would it be an M10?

So what about drill bit size
So u know when u shop for the heli coil kit for a certain bolt size, like an M12 or M14 for example, that kit will tell you what size drill bit you need then just measure yours if you got a set.
I used a Perma-Coil kit to repair my front Brembo caliper. They call for a 31/64" drill bit for M12 X 1.5 and 13/32" drill bit for M10 X 1.5.
Just curious, but why work on metric materials and use metric references, but then measure everything in SAE? Made me laugh. Love the methodical approach, and host commentary. Quite good.
I actually called myself out at 11:00 that I should have been using metric, must have had a brainfart ;) thanks for the comment.
