Plug taps, essential tools in threading, are used to create internal threads in pre-drilled holes. They feature a tapered cutting edge for easier starting and gradual cutting, making them suitable for general-purpose threading in various materials. This guide explores their applications, types, and selection criteria, providing valuable insights for manufacturers and machinists.

Understanding Plug Taps

Plug taps, also known as second taps, are a type of hand tap used to cut threads in a hole. They are designed to be used after a taper tap, but can also be used as a single tap in through holes or soft materials. They are identified by having 3-5 threads chamfered (tapered) at the end, allowing for gradual cutting action. They are an indispensable part of the machinist's toolkit, especially for creating clean and accurate threads.

Key Features of Plug Taps

• Tapered Cutting Edge: Allows for easier starting and gradual cutting.
• Versatile Application: Suitable for general-purpose threading in various materials.
• Intermediate Cut: Typically used after a taper tap for a more complete thread.
• Material Options: Available in high-speed steel (HSS), carbon steel, and other materials.

Types of Plug Taps

Plug taps come in various types to cater to different threading needs. Understanding these types is crucial for selecting the right tap for a specific application.

Hand Plug Taps

Hand plug taps are designed for manual use with a tap wrench. They are ideal for small-scale threading jobs and offer precise control over the threading process.

Machine Plug Taps

Machine plug taps are designed for use in power-driven machines like drill presses or CNC machines. They offer faster threading and are suitable for high-volume production.

Spiral Point Plug Taps

Spiral point plug taps, also known as gun taps, feature a spiral point that pushes chips ahead of the tap, preventing chip clogging in through holes. The offerings from Wayleading Tools, a leading plug taps manufacturer, include options like these. Visit www.wayleading.com for details.

Spiral Flute Plug Taps

Spiral flute plug taps have spiral flutes that pull chips back and out of the hole, making them ideal for blind holes where chip evacuation is crucial.

Materials Used in Plug Taps

The material of a plug tap significantly affects its performance and lifespan. Common materials include:

High-Speed Steel (HSS)

HSS plug taps offer good wear resistance and are suitable for threading a wide range of materials. HSS is a popular choice due to its balance of hardness and toughness.

Carbon Steel

Carbon steel plug taps are less expensive but offer lower wear resistance compared to HSS taps. They are suitable for threading softer materials like aluminum and plastic.

Cobalt Steel

Cobalt steel plug taps offer enhanced heat and wear resistance, making them suitable for threading harder materials like stainless steel and titanium.

Powdered Metal (PM) Steel

PM Steel plug taps are made with a powder metallurgy process, allowing for high alloy content and superior performance when threading difficult-to-machine materials.

Selecting the Right Plug Tap

Choosing the correct plug tap is crucial for achieving optimal threading results. Consider the following factors when selecting a tap:

Material to be Threaded

The material of the workpiece is a primary consideration. Softer materials like aluminum require less aggressive taps, while harder materials like stainless steel require taps made of cobalt steel or PM steel.

Hole Type

Consider whether the hole is a through hole or a blind hole. Spiral point taps are ideal for through holes, while spiral flute taps are better suited for blind holes.

Thread Size and Pitch

Ensure the tap's thread size and pitch match the desired thread specifications. Use a thread gauge to verify the thread dimensions.

Tap Style

Select the appropriate tap style based on the application. Hand taps are suitable for manual threading, while machine taps are designed for power-driven machines.

Applications of Plug Taps

Plug taps are used in a wide range of applications, including:

General-Purpose Threading

Plug taps are commonly used for general-purpose threading in various materials, including steel, aluminum, and plastic.

Automotive Repair

Plug taps are used to repair damaged threads in automotive components, such as engine blocks and cylinder heads.

Manufacturing

In manufacturing, plug taps are used to create threaded holes for fasteners in various products, from electronics to machinery.

Plumbing

Plug taps are used to create threaded connections for pipes and fittings in plumbing systems.

Tips for Using Plug Taps

Following these tips can help ensure successful threading with plug taps:

• Use a cutting fluid to lubricate the tap and reduce friction.
• Apply even pressure when tapping to avoid breaking the tap.
• Back the tap out periodically to break chips and prevent clogging.
• Use a tap wrench with a comfortable grip for better control.
• Clean the tapped hole after threading to remove any remaining chips.

Troubleshooting Common Issues

Even with careful use, issues can arise when using plug taps. Here's how to address some common problems:

Tap Breakage

Tap breakage can occur due to excessive force, incorrect tap selection, or inadequate lubrication. Use the correct tap for the material, apply even pressure, and use a cutting fluid to prevent breakage.

Thread Stripping

Thread stripping can occur if the tap is forced or if the pilot hole is too large. Ensure the pilot hole is the correct size and avoid applying excessive force.

Chip Clogging

Chip clogging can occur in blind holes. Use a spiral flute tap and back the tap out periodically to remove chips.
