Different Types of Taps, Dies & Wrenches
Types of Taps
- Plug Taps: A Plug Tap is the best tap for general applications. It is easy to start and requires very little torque to turn. Because of their tapered starting threads, they are ideal for through-hole applications.
- Bottoming Taps: Sometimes, it is necessary to tap threads in blind holes. A bottoming tap is needed to produce as many full threads as possible if the hole’s depth is not too great. This tap can produce sufficient threads for full strength if the bolt holes measure approximately 2 1/2x the diameter.
- Taper Taps: Taper tap can be used to cut very precise threads using very little torque. They are much easier to use than a plug tap because of their tapered design. Tapered taps are rarely used and are often not included in the sets.
- Pipe Taps: American Standard Taper Pipe Thread (NPT) is the most common threads used in residential and commercial plumbing and hydraulic and automotive applications.
Types of Dies
- Circular Dies: For cutting threads in bolts exteriors, circular dies are the most popular type. These dies will be included with almost all sets.
- Split-Circular Dies: Split circular dies are able to be divided in half, or just one split. This allows them to take larger materials. These dies are used to cut shallow threads in the first pass and then more intricate threads as the die is tightened around a bolt.
- Die nuts: Die nuts can be used as a follow-up tool to sharpen already existing threads, but they don’t create new threads.
Types of Wrenches Needed
- Tap wrenches: A tap wrench looks like a long, thin piece of metal with a rectangular opening in the center and adjustable teeth. These teeth can be adjusted to fit around the tap’s end so that it can cut threads without slipping.
- Die wrenches: A die wrench can be compared to a tap wrench. However, the center of the wrench is designed to take dies centered. The wrench is then fastened with one or several set screws.
- Ratcheting Tap and Die wrenches: You can save some time and effort by using a ratcheting tap and die wrench. This type of wrench allows you to cut clockwise. However, it won’t loosen if you turn the wrench counterclockwise until it has been released. This is to avoid tiring out if you use a clockwise hand-over-hand cutting technique that quickly becomes tedious.
Things To Consider While Buying The Best Tap And Die Sets
There are hundreds, if not thousands, of tap and die sets on the market. Before you purchase your next one, it’s a good idea to consider these essential features.
When buying a new tap & die set, the most important thing to consider is the quality of the components. There is a strong correlation between the purchase price of your product and the quality that you can expect.
You should avoid buying the cheaper full sets. They may seem like an excellent value, but the frustration of having the threading apparatus break halfway through a job can be too much. Do you want to tap stainless with a cheap tap and die set? Don’t bother – your tools will soon become useless and gnarled.
If you are looking to make high-quality nuts or bolts for industrial use, then a simple steel alloy will not suffice. If you are a regular DIYer who needs to do some garage repairs, you can look for tap and die sets made from high-carbon steel. High-carbon steel is somewhere between alloy steel and the more expensive high-speed metal used for major industrial projects. A high-carbon steel set is more expensive than an alloy steel set. The quality difference will be evident almost immediately.
Versatility & Range
The number of parts in tap and die sets can vary widely. A woodworking set might only have three pieces, while a metalworking set with more pieces may contain more than 100. This is especially true if the taps and dies are available in both SAE and metric sizes.
A tap and die set with more parts is generally considered a positive thing. More parts in different sizes allow for more jobs. But remember, part quantity is not enough. Part quantity and part quality must be balanced, as we discussed above. However, different sets might contain different tools. Given your needs and the types of jobs you want, it is important to examine the number of tools in a particular tap & die set and which tools they contain.
Sizes- Metric and SAE
Different sets could be denominated either according to the Metric system based on European sizes or to the SAE system based primarily on the U.S.
Metric taps and dies measurements can be determined by measuring the distance between thread crests measured in millimeters. The thread’s crest is the protruding portion, whether it is external or internal. The root, on the other hand, is the groove between the flanks connecting the crest and the root.
The SAE tap and die measurements can be understood much more easily. The components are measured in threads per inch (TPI). Simply hold a measuring tape to the thread pattern and count the number of threads in one inch. You could also use a pitch gauge if you have one or if it comes with your tap-and-die set. This gauge can be used to determine the SAE or metric dimensions of your tap and die.
The material you choose to use is crucial since you’ll need to cut through the metal when utilizing the set. If you select a lower-quality toolset and then try to use it with an alloy that is more difficult to work with, it’s likely that you won’t be able to thread it correctly. Best tap and die sets are typically made from high-speed steel or alloy steel to ensure they are compatible with all kinds of metals. The most efficient sets are carbon steel, HSS, and titanium or cobalt. These sets will be able to work on stainless with no problem.
Another thing to think about is the coating applied to the tap and die kit. Metal coating technology has developed significantly in the past 20 years, and now there are a variety of coatings that improve the efficiency of cutting tools.
Titanium Nitride ( TiN)
The most popular coating or metal treatment used for tools includes Titanium Nitride (TiN). TiN improves the effectiveness of the hardness of an HSS (also known as High Carbon Steel) tool from 60 Rockwell C Scale to 80 Rc. The extra hardness dramatically extends the life of the tool and makes the cost of TiN worth it.
One of the most ancient and popular metal coatings is Black Oxide. The finish improves the capacity that the tools’ surface holds the lubricant. It increases the flow of chips and protects the drill bit from corrosion.
A few of these sets for taps and dies could cost quite a bit. The one thing you don’t want to do is pick an item that is damaged as you carry it from one place in one place to the following. Storage cases help keep the die and tap set in good condition for the long haul. Cases can guard against rust and corrosion, especially in an area with high humidity.
Good quality tap and die sets vary in price, ranging from less than $100 to over a thousand. Those who have been machine operators for a long time will know that it’s worth investing in an excellent set of dies and taps. If you’re new to the field and are just beginning, it might be a bit more difficult to assess.
Consider the frequency you plan to utilize your die and tap set to determine the cost and everything else associated with the cost. Most of the time, getting smaller units that are more durable is likely to be a wise choice at the end of the day.
Tips for Using Tap and Die Sets
- When cutting threads to form a rod, it is good to cleanse the threads by taking three turns off every three turns you cut. This will help you keep an even cut.
- If you’re cutting an old bolt, be sure to lubricate the rod so that you get it to cut faster into the material. Lubricant can also help prevent overheating that is caused by metal-to-metal contact.
- A die may not work well on a flat-ended rod. It is necessary to use a grinder to create an end that is beveled on the rod.
Tap and die sets are generally priced based on their functionality and versatility when it comes to them. For instance, if you’re a DIYer who needs to utilize only one or two sizes of taps, you can purchase the cheapest die and tap set you can find. Again, suppose you’re required to use all of the different sizes needed to finish your job, and you require all the tap and die sizes. In that case, it’s smart to invest more to purchase a high-quality item that will last longer than less expensive ones.
