6 Best Tap and Die Set 2020 Reviews

1. Greenlee DTAPKIT 6-32 to 1/4-20 6-Piece Combination Drill and Tap Set

This drill and tap set is constructed from high-speed steel, rather than carbon steel, for longer life.

I like that this Greenlee set saves time as comprehensive demurring, tapping, hole drilling, and countersinking are done in one operation with a power drill.

You can tap up to ten-gauge metal with this handy set. It even includes a quick-change adaptor which will assist you to tap, drill, and countersink, while it can even drive fasteners. This set’s strong hex shank guarantees solid connection to the drill. Back-tapering evades damage from over drilling.

If you are looking for a kit for heavy use, this is not the one. However, if you need to get some projects done and not pay out a high amount, this kit just might be for you.

2. GearWrench 3887 Tap and Die 75 Piece Set - Combination SAE / Metric

There is so much to like about this set. All of the taps and dies latch into place with index holders for the taps.

The ratcheting torque wrench is really convenient for taps and makes everything so much simpler. 

The durable blow mold case is very well made and keeps everything safe. The warranty is a huge plus.

Quick Tips On Buying Tap and Die Sets

If you are not quite sure what you are looking for in a tap and die set, it can be slightly confusing. You can end up battling with yourself what price you are willing (or can afford) to pay or just how big of a set you really need.

Do keep in mind that, no matter what size set you purchase, you will open up a whole new world of capabilities that you might not have had before. The set you purchase can really depend on what you will be using your set for. Most DIY aficionados have no idea how significant a tap and die set is until they own one. 

Case Type

To make sure that all of your pieces and components are securely kept in their place, it is best to find a tap and die set with a sturdy plastic storage case. You don’t want to waste time fumbling around with your materials without a decent case. 


It is essential that you buy a handle that is painless to use. No one wants to use a handle that is cumbersome and difficult. If you have to push too much, you can end up with stripped threads and your taps and dies wrecked. 


Tap and die sizes are also very significant. Preferably, the best tap and die set should cover both metric sizes and SAE for flexibility. A benefit of picking up a larger set is that you won’t be left in the lurch awaiting another tool to arrive if you’re doing a project that requires other sizes in the future.


Build quality, which we will discuss shortly, is completely related to the kind of steel used in fashioning the tool. High-speed steel can be a good investment, rather than plain-finish steel, if you will be using the tap and die set frequently. 

Quality of Build

You need to carefully consider the build quality of the set you purchase. The old saying ‘’you get what you pay for’ can apply. If you are just looking to do a small job, here and there, then a cheaper kit can work for you.

Still, check the materials used and reviews of the product to make sure they will do the job you want. If you will be putting your tap and die set to heavy use on a variety of projects, it would be best to purchase a good set in a higher price category, with more pieces.

Best Practice for Using Tap and Die Sets

Using a tap and die set is astonishingly easy if you pay close attention to what you do. Careful work can prevent cracks and breaks while keeping your equipment in good shape. A perfect finished product is worth the effort and patience involved. 

Not All Lubricants Work for All Materials

The proper use of the correct lubricant is crucial when tapping and threading. Do your homework to make sure the lubricant you use is the right match for the materials you are working with.

Using the wrong lubricant can cause mayhem with your work. Note: DO NOT lube cast iron unless you have a water-based coolant you can flood it with. Alternatively, you can use compressed air to clear graphite chips. 

Taps and Dies

Pick the right-sized tap and drill that is suitable for the job. Tap and die calculators can be located online. To produce proper holes for tapping, make sure your equipment is well-cared for and the proper lubricant is used. Begin tapping at a slower speed and increase slowly to find the ideal speed. Do not jump into this at a higher speed to avoid mishaps and cracks. 

Thread Cutting Tips

Using the proper tools, techniques, and lubrication is key to successful threading. Your taps and dies must be tougher than the materials they are going to cut. Due to their brittle nature, taps can easily break.

It's best to use the correct T-handle for taps instead of pliers or wrenches. The asymmetrical stress on the tap can cause it to crack or go off-center. Another best practice, to make sure you get a decent clean cut, is to “cleanse the threads” while you die (or tap) by backing out around three turns every time you do three turns forward.

Final Note

Whether you are a heavy professional user or a DIY amateur, one of the posted tap and die sets above will make your life much easier. The right tap and die set can make various projects much simpler and give you options you never dreamed of.  

A good set makes a big difference in your thread cutting work. We hope this best tap and die set list helps you find the right set for you (or at least gives you some things to think about when purchasing one). Happy thread cutting!
