Wurth Time-Sert | thread repair kit

[smarthome]

I have used Cross Wire Inserts (Helicoils) for many years, I have only had a few wind out upon removal of bolt or stud. I just clean the thread out with the tap, and wind in a new Cross Wire Insert, job done. When repairing many stripped or damaged threads, the Cross Wire Inserts are far cheaper than other threaded bushes. Also if the stripped hole is very close to the material edge, the Cross Wire Insert requires a smaller new hole than an insert type such as these.

Great work! I have the Time Sert kit, and at the same time, I was looking for alternatives. I purchased the SENNMONN kit on Amazon, and it functions the same, saving me a lot of money. Looking forward to your video content updates.

Informative video showing an effective solution and alternative to helicoils (which I don't trust in use by the way!!) Just a few things to point out here drill you showed wouldn't really be effective in a normal 3 jaw drill chuck unless you grip the shank of the drill - the reason it's square is so it's only to be used in the tap holder...… you're essentially using the drill as a reamer to obtain the correct sizing of the hole for the tap used...…..also a 'few turns of the tap wrench and a slight turn back to break the chip' isn't really the way unless you potentially want to snap the tap in the hole.... especially in harder materials like steel!! I recall from my apprentice workshop days reciting "1/2 a turn round, 1/4 turn back" which I still do to this day if I have to do any manual tapping of holes.... just a couple of pointers as everyday is a school day as they say... Thanks

I always had my problems with the helicoil system. I am using the Time-Sert since more than 15 years mostly on motobike engines. Since then the screw connections have been holding up again.

Thanks for showing us this kit. We never know when we need it. Spot on. And the explosion was interesting too 😃

Fantastic product that should work all the time, every time.

I won't be in the market for this type of product but enjoyed the video nonetheless.

Thanks for taking the time to film and upload, thumbs up.

Thanks for making this as i was only aware of the helicoil type inserts. Much prefer those eclipse type forged tap wrenches too. Miles better than the cast aly ones that break if you drop them. Cheers.

Never had a helicoil fail like that, BUT, that being said i buy the genuine stuff. I hear (grape vine) that outside of a few German made products and some French ones, everything else short of the original product is garbage. Lower quality steel, different geometries etc.

There is one thing i do, whenever the thread really needs to remain in place. It's not something everyone can do, but i have full confidence in the strength of the repair, and that is, i spot weld the last coil section into the original metal. Obviously, this doesn't work for dissimilar metals, and you need to have a copper thread plug to maintain the hole, but it works exceptionally well to keep them in. On my brother's farm, i've done this to every farm tool that lost threads, we both had equal thoughts about losing threads or actually seeing them come out like in your intro, like a spring, so we decided to go the extra mile.

I think the toughest test is the bar that keeps his steps upright, in season, that sees a lot of use and whilst it would not lead to any catastrophic failures if it did break, it hasn't so far despite being removed with regularity to reach the battery well.

good for stripped spark plug hole too with the appropriate sized insert.

if you look closely at the last two threads on the insert they are not formed the same as the rest of the insert. when you use the driver it cold rolls the last two threads which then locks the insert int to the work piece . the driver ideally needs to be able to exit the end of the insert to lock it into the workpiece tightly,


they are a great repair item and in my opinion better than helicoils .




i used to use them a lot in a previous job. .


spark plug inserts where a daily occurrence as were inserts for sump plugs in ali sump.

Great video, thanks for making it. But what I don't understand... the drill bit is larger than 6mm, isn't it? Must be since the TimeSert-insert's OD must be larger than 6mm. So how come the drill bit fits into the hole with the stripped thread? That hole must be ~6mm. Is the drill bit tapered? Asking because whenever I've done helicoils, getting the initial drilling straight (perpendicular) is the hardest part because the drill bit rocks around on the surface - it doesn't get any guidance from the hole because it's not in the hole (yet). Thanks.

A good alternative to the helicoil system, thanks for this! 👍

[davewhite]

Handy to know there's an alternative to the Helicoil type. Not cheap, but then what price is a replacement part?
Another great video. Shows the method of use clearly and concisely.

I have to disagree with you.
I have used helicoil for past 40 years 100's if not 1000's of times and Time sert occasionally.
I have never ever had a helicoil come out but I have had at least 8 timeserts, fitted to spark plug threads (not by me) that have wound out on the plug seat.
As in all things, preparation is everything
I would always use a genuine helicoil over any other thread repair system

[dazaspc]

Not all helicoils are made equal. Many off brand units that are frequently interchanged and don't work well. That said the Wurth units are the best for hard threads in soft material. I have used them into aluminum on vibrating tables running at up to 20hz and when they do come out can be replaced with a new insert and locktite with little problem. However they don't like heat compared to a Helicoil.

I would advise using cutting oil when drilling and especially when tapping holes. Great vid

[oyunageldim]

hi, the thing that is stuck in my mind is this: my motorcycle's crankcase plug slot was licked and its size is m14x1.5. I want to put m14x1.5 size plug again. I want to get and do time-sert for this, but what measure should I take? What should be written on the time-sertbox?

[jamiedykes]

Much better but also 3 times the price of a decent coil type repair :) great vid as always!

[mrstephen]

If the original hole was say an m10 when repairing the thread do these or helicoils then change that hole to a larger bolt so an m10 will not fit anymore ?

Thanks for the information. This is a great channel.
