EFFICERE 40-Piece Premium Tap and Die Set, SAE Unified Screw Thread, Size #4 to 1/2” | Include UNC Coarse, UNF Fine and NPT Threads | Essential Threading Tool Kit with Complete Handles and Accessories

Not 2 bad, good bang 4 buck.

I thought it was going to be another cheapy junk set like I had just returned from Harbor Freight that I could not even tap and already tapped hole in ABS plastic. what garbage they have. This set is really nice and all the size's are etched into each piece to you know what size you are looking for. Not like the other company that it wiped right off and most did not have them etched. If you don't know what the size is, then what good are they. They were all organized nicely. Worked quickly and perfectly on ABS plastic. Thanks so much. 😍😍

These are, in my opinion, fine for DIY projects. Not for professional use. I put some Loc-Tite on the tap handle because it would unscrew during use. Funny that a Tap/Die set would have loose threads holding the handle on... Anyway, for the price and to have a set on hand, I don't think you could do much better.

The EFFICERE 40‑Piece Premium Tap and Die Set has been a great addition to my tool collection. I’ve used this set many times for different projects, and it has worked very well every time. The taps and dies cut clean threads, feel precise, and haven’t shown any signs of premature wear. The range of metric sizes, including both coarse and fine threads, makes it very versatile, and the included handles and accessories are solid and easy to use. Everything fits nicely in the case, which keeps it organized and easy to grab when needed. Overall, this is a good‑quality set that performs reliably and feels built to last. Whether for automotive work or general repairs, it’s a dependable threading kit that I’d definitely recommend.

I needed to cut some 6-32 threads in some stainless steel rods used to secure engine baffles underneath the engine for a Vans RV-9 Home-built Aircraft. I tried to make the threads with my Harbor Freight die that is made of carbon steel but it would not even scratch the surface of the stainless rods. I needed a much harder die that could cut stainless steel. I did some research and found that high quality dies that are made of Cobalt Steel, Titanium Steel, or High Speed Steel (HHS) could cut stainless. I happened to find this set and the product description said it is made of GCr15 Bearing Steel hardened to Rockwell 60 and could cut stainless. I didn't know what GCr15 steel was but I found the following definition online: GCr15 steel is one of the most commonly used Chinese bearing steels, it’s a high carbon chromium bearing steel with high hardenability, high & uniform hardness after heat treatment. I also looked up the rockwell 60 number which is based on a standard hardness scale that goes up to 62 so 60 is at the top of the range when it comes to hard steel. I was still a little skeptical since the price of this set was very low compared to other sets or individual dies I could find for cutting stainless. I decided to take a chance and try this set out since it had lots of good reviews saying the taps and dies in this set seemed to work well for most everyone who bought them and also several good comments about the customer service willing to refund customers who had any dissatisfaction with the product. My set arrived from Amazon in 2 days from ordering. I tried them out over the weekend and they cut very nice accurate threads in my stainless steel rods very easily while using a couple drops of tap magic oil. This set performs as advertised, it is made of industrial quality steel that can cut stainless steel. The other reviews also said the handles the set comes with are lower quality but I would say the handles are comparable to the ones that come in a Harbor Freight set. I also found on Amazon a very handy 5 piece set of GearWrench ratcheting handles for taps and dies that fit perfectly with this set and made the job easy. For the money, I don't think there is anything out there that compares to the quality of the steel in this set for cutting hard material.

Not the most precise machining. Some of the dies don’t cut well so I sent it back.

After looking at this tap and die set carefully. It seems that it is made with High Quality I did have my doubts, the machine work and how sharp both the die's and tap's are very well made. So if you want a great set of tap and die metric set look no further, High recommended.

I bought this set to re-tap some large canopy tent connectors. This set easily accomplished the mission. I was able to do about 35 re-taps and screwed in some 5/16 eye bolts with no issues. The taps and wrench were durable and it came in a decent case to hold the taps, dies and wrench. For the price, its really tough to beat and it did what it was made or set out to do. Highly recommended. Great value!!

جيده تفي بالغرض وخامه جيده

Muy buena herramienta, para trabajar en cuerdas de turecas y tornillos

It's a good tool, but unfortunately it lacks the dimensions needed in mechanics.

Poor quality and storage box, I return it back.

I recently purchased this product and was extremely disappointed with the quality of the product. The taps and dies didn't work on a soft metal even at the first attempt, making it difficult to create threads, and several of them broke while in use. Overall, I would not recommend this product to anyone and I am extremely disappointed with my purchase.
