BZBMGMO M11x2.0 Two Sizes Thread Repair kit (Including 5 Inserts 16.2mm Length,5 Stainless Steel Inserts 28.2mm Length)

I stripped the threads out of a ls1 aluminum block and this got me back on the road at a fraction of the price of those big box kits

Pretty straight forwardUsed masking tap to cover entire bank 2TAKE YOUR TIME TAPPING.Worked good.Worth the price

Length of product not long enough, seems like product is only for shallow holes. I order other parts from gavan tools to tap my LS 5.3 engine block.

Pretty simple to use I used it on gen 4 ls 6.0 pretty straight forward about a 5-7 min job in all hold up good and allowed me to do all torque specs I replaced 2 that stripped threads out

This kit was a lifesaver with a broke off bolt and a aluminum Chevy LS engine was impossible to extract due to the loctite disc kit. Drilled that out in the insert is still holding strong with high torque specs on this engine. I was not confident that this product would hold however it holds perfect! It's not quite as easy to use as the instructions say it is for professionals, so be careful it's not used right? You can destroy your engine

These thread repairs saved on expensive block replacement.

It did what it was intended for, drill bit nice and sharp, tap was sharp, the beveling tool would get gummed up and didn't quite go deep enough but with a little modification that was cured. The insert tool would locked into the inserts because the inserts were full of debris from machining. Other than that worked ok.
