Things were going ok, and then the tap broke off in the hole.

Nice tap and insert "wrench" both included as described.

The thread-tapping tool fit readily in the thread-tapping handle I already owned (the kit doesn't include that component) and the blue-handled tool made it easy to correctly install the helical insert. And the repair to the housing of my high-speed router is holding well.The final test is how well the helical insert stays in place. But if it doesn't stay put, one can use a thread-locking compound between the insert and housing.

I was happy to find this unicorn of a size available. Other sources charge an arm and leg for this. This wasn't cheap but you have to do what you have to do. A drill bit would have been nice, especially at this price. I had to use a close equivalent wire gauge size drill. Installation went fine, no problems with respect to the functionality of the product itself.

I ordered the M14-1.5 (1.5D/21mm length) economy kit, but similar to another reviewer, received a kit which contained a different size set. Mine was labeled as ordered, but contained the parts for a 1/2-20 (1D/14mm) kit, which I determined by both tap imprint and comparison both to the bolt to be installed and a thread pitch image from the Bolt Depot fastener tools PDF (make sure to print at 100% scale). Note that you have to stretch the coils to match the pitch image if you want to measure: they do not arrive expanded to length at rated pitch.In the attached image, the left kit is the first received, the right kit is the replacement. Clearly different contents.Since I needed this item for a repair this week and it was out of stock at Amazon, I reached out to E-Z Lok directly to see if they could help. They responded within a few hours and shipped me a replacement kit with the correct items the same day via Next Day Air. They even included a Certificate of Conformance (asserting that the shipped item matched the ordered item).I'm delighted that E-Z Lok stood by their product, and my oil pan is now back in business with a solid thread repair after the drain bolt hole had been stripped during previous ownership: an aftermarket Dorman toggle bolt plug had been there when I bought this vehicle used, and it was starting to leak). This is my second bolt hole repair with E-Z Coil. It's a well-designed product, and with this kind of customer service, I'm a customer for life.

No incluye la broca necesaria, y no pude encontrar que tamaño se necesita antes de comprar. Ya que lo recibí, en la parte de atrás dice que se necesita una broca de 10.3mm que es una medida muy dificil de conseguir, al menos en opciones económicas.

e-z lok thread inserts are really well-made and work great.they have variations in their kits.. some that include the required drill bit and or the pin punch or not. and the other variable is the depth of the insert: 1x 1.5x or 2x the diameter of the insert. so, make sure you have what you need. Any pin punch that will fit can be used so there's no need to buy a kit that includes that. You can also search for what drill you need and buy that separately if you need it.Finally, note that the tap included in this kit is an STI tap, which means it's not the same size as the insert's end result. Example: if you have the 1/2" insert, the tap isn't a a 1/2" tap, it's bigger because it has a hole that the 1/2" insert fits in. The insert is 1/2" on the INSIDE and its outside diameter is obviously larger. that' what "STI" means.

It just does work perfectly indeed - If you follow the simple 3 steps (1 - drilling, 2 - threading ,3 - placing the insert) using the tools provided in this same kit, it will do what it says it will do.I have a track bike and as such there is constantly maintenance and the need of removal certain parts (seat, farigins etc) in a often basis to perform such maintenance. As the chassis is made of aluminum, at the some point is almost expected that the threads for the bolts holding these parts will give away... I already performed 3 repairs on the frame of my bike using this kit and it worked perfectly all three times!I'm about to buy the M10 1.25 of this same kit as well for another area I expect will need repair soon.
