Review on TIME SERT 1 25 Metric Drain Repair by Matt Heringer

The tough men at the local mechanic mistook the oil drain plug in my Lexus SC400 for the nut that holds the blade to the helicopter, so the oil drain plug was ripped off . I was either going to drill and tap a larger size or shoot a spiral when I found these tubes and they looked good so I gave it a try. The set arrived and I found that the square shank drill bit and countersink were too big for my set of taps so I bought a set of sockets for the #9, 10 and 11 taps. Square shank size, their size is .370. ", which is too big for #9 (.360) and too small for #10 (.406). I've successfully drilled a nice and square hole using lots of cutting fluid, aka oil, that was still leaking out of the hole - for hand cutting at low speed this should have been fine. I then used a countersink. The pilot was too small for the hole so the countersink wobbled a bit more than it should. One of the Grooves on the countersink broke immediately which was disappointing considering I was hand cutting with a small lever under the machine.I slowly brought the countersink to the specified level and before I was done there is another groove The hole and countersunk hole were pretty rough so I took a spoked wheel and deburred part of the cloth, then tapped The faucet was square but it took a lot of effort to trim the thread - the hole f The faucet seemed small, it was slow and tedious to thread - 1/4 turn forward, all back, clear out chips, another 1/4 turn. The insert entered smoothly and sat in place. I then flushed the hole with a couple gallons of oil, screwed in the drain plug to spec and everything seemed to work fine - no leaks. It would have been 5 - if the flutes hadn't broken, the countersink pilot was a bit larger and the bit size maybe a few thousand larger. Next time I'll probably just drill and cut a larger drain plug.
