Components Of Nut Tap

Body: This is the longest and most important part. The body of a tap is what does the cutting. It contains both the thread chamfers and the full threads.

Shank: The shank is located just above the body. It is smooth and has a cylindrical shape. The shank length differs according to tap type.

Tang: This is the squared-shaped part above the shank. Based on the mode of operation (manual or automatic), manufacturers fix the tang on a holder to rotate the tap.

Flutes: Flutes are grooves on taps that accommodate and expel the chips during tapping. They come in different types and shapes based on the tap type.

Land: The land is the threaded part between the flutes.

Heel: This is the slanted area behind the threads.

Cutting Face: This is the surface of the tapping tool that comes in contact with the material.

Coating Types for Nut Taps

AlTiN - Aluminum Titanium Nitride. Forms a layer of aluminum oxide at heat increasing its surface hardness and providing better performance where no lubrication is used. Best for steels, cast irons and alloys.

CrC - Chromium Carbide Coated Taps have and advantage over other tap coatings when used in abrasive and corrosive environments. Suitable for steels, cast irons and alloys.

TiCN - Titanium Carbo-Nitride coated taps are similar to TiN coated taps, however the addition of Carbon increase the hardness and improves surface lubricity. TiCN coatings are best used on HSS taps.

Oxide Finish - Also called Black Oxide, is a surface finish that prevents chip building, galling and welding. Oxide coated taps are best when used on low carbon, stainless steels and ferrous metals.

TiN

Titanium Nitride is a general purpose PVD coating that increases the hardness and the oxidation temperature of the tool. Titanium Nitride coatings work very well with HSS tools and is a good coating in steels and cast irons.

Nitride

Is a thin coating that supports surface hardness. Used in abrasive and wearing applications.

Bright (Uncoated)

These taps have a smooth polished finish on the tool for increased chip flow when tapping softer materials such as aluminum, wood and plastic.

Considerations For Using Nut Taps In Blind Holes

Chip Evacuation

When cutting threads in a blind hole, chips can accumulate at the bottom of the hole, causing the tap to bind or break. To prevent this, it is important to use a tap with proper chip flutes and to apply a suitable cutting fluid. The cutting fluid helps to lubricate the tap and flush out the chips, ensuring a smooth and efficient threading operation.

Material Compatibility

The material of the workpiece also affects the threading process. Different materials have different hardness and machinability, which can impact the performance of the tap. For example, harder materials may require a slower feed rate and a more robust tap design to prevent breakage. It is important to choose a tap that is specifically designed for the material being threaded.

Tool Maintenance

Proper tool maintenance is essential to ensure the longevity and performance of the nut tap. After each use, the tap should be cleaned thoroughly to remove any chips or debris. It is also recommended to store the tap in a dry and clean environment to prevent corrosion.

FAQ

Q: Can thread taps rethread an existing hole?

A: Yes, a thread tap can cut threads in an existing hole. Engineers and machinists across many construction industries have a tapping set in their toolbox to clean out and rethread holes as needed.

Q: What is the nut tapping process?

A: The nut tapping procedure can be divided into five processes: feeding, tapping, reversing, retracting, and discharging. Figure 2 presents a schematic of each process. In the feeding process, the nut is pushed to the tap after unloading, and only the tap rotation creates torque.

Q: What is the difference between NC and NF taps?

A: NC and UNC mean coarse thread. NF and UNF mean fine thread. NS means special thread. Pitch Diameter is the basic dimension of a screw, threaded hole, or a tap the diameter of an imaginary cylinder, the surface of which passes through the thread where width of thread and space between threads are identical.

Q: Why lubricate a thread tap before tapping?

A: It is important to apply lubricants directly into the drilled hole and the tip of the tap before tapping a hole. This aids the easy removal of chips and helps to reduce friction.

Q: How to use a bolt tap?

A: Insert the tap into a T-handle and add drilling oil to the hole. Fit the end of the tap into the hole pointing straight down and aligned with the hole. Rotate the T-handle clockwise using smooth rotations. Don't apply much pressure; allow the tap to thread the hole on its own.

Q: What type of tap is used to cut threads on the bottom of a blind hole?

A: Bottoming taps, also known as plug taps, are cutting tools designed for creating threads in blind holes, which are holes that do not go all the way through a workpiece. Their unique design allows them to cut threads to the very bottom of the hole, ensuring a complete and secure thread engagement.
