Large Diameter Tap and Die Set

Most threading jobs are for thread sizes 1/2″ in diameter or smaller. Larger thread sizes are typically encountered when installing or maintaining machinery or repairing farm equipment. If you are a tradesman, large equipment mechanic, metal fabricator, mill wright, or maintenance person a Large Diameter Tap and Die Set is a must-have item for getting the job done as quickly and efficiently as possible.

Large diameter threading tools are expensive, especially when purchased individually. And waiting until a threading job comes along to go ahead an order the appropriate size tap or die can hold up an entire project. But finding the right set with the correct range of large taps and dies takes up time when you need to be working.

I already taken the time to do the research and tracked down some quality large diameter tap and die sets.

Why Should You Consider my Advice?

As a veteran machinist/toolmaker I have a lot of familiarity with all types of threads and thread sizes as well as the tools used to create them. I have hands-on experience using all sizes of threading tools so I know what features work best.

My Recommendations

Here are some sets with Large Diameter taps and dies up to 1″ and/or 18mm for you to take a look at. Depending on your particular requirements there are both SAE and Metric thread series to choose from.

I have evaluated all of the customer reviews to make sure they are legitimate and reflect the customer’s true experience with the product.

I’ve included both professional grade sets for commercial use and less expensive budget sets for occasional use. Each of the sets BELOW will cut proper fitting threads and should provide many years of service when used correctly.

ProTip: The biggest cause of a broken tap or die is from not using a quality thread cutting oil or fluid such as Tap Magic.  This product acts as a lubricant that increases tool life.  It dramatically reduces the possibility of tap breakage, and produces cleaner, better finished threads with less effort.
