Excellent Metric Tap and Die Set for DIY Repairs
This tap and die set worked great for repairing and creating threads. The tools are easy to use, well organized, and seem durable. It includes a good variety of metric sizes for most DIY and repair jobs. Great value for the price.

Good value but case insert(s) are it's failing.
I bought this set to tap the occasional metric hole and chase / renew messed up threads. Very large range of sizes. Taps and dies look good for the money. Decent grinding, no obvious flaws. Tap handles, wrenches and die stocks look so so. The die stock bodies are die castings. Not too concerned about them, have older USA made ones I can use. I imagine they would be OK though. The one fly in the ointment are the case inserts. They are very flimsy plastic. They will not retain the contents. The set arrived with half the contents all over the inside. Don't plan on carrying the case like a suitcase. The contents will get scrambled. I think I will cut pieces of thin plexiglas or heavy cardboard to put over each layer to make sure the contents don't fall out of the wells. Both inserts need to sit in the bottom of the case on top of each other. The one insert will not sit in the top of the case as shown in the photo. Also, one photo shows a thread pitch gauge, this is not included. I have some, so not a big deal. If you need a metric one or a thread checker, order one when you buy the set. Overall a good value for the price, given its one big flaw. Edit / Update - I cut two thin pieces of plastic and put one over each tray. When the case is closed the plastic keeps the contents in the individual wells. Problem solved.

Wasn’t the best for storage
The tools were good quality and I’d say it’s a good value for the money the issue was with the storage box - I received the product and opened it and all the tools were thrown all over nothing stays in its spot at all and it’s super messy and I like organized storage boxes.
