Irwin 6-48 NS HCS Plug Tap - Bulk (1121)

The Irwin 6-48 NS HCS Plug Tap - Bulk (1121) is an essential tool for creating or repairing internal screw threads. Made from high-carbon steel, this hand tap is specifically designed for manually threading holes. Its 6-48 NS (National Special) size is commonly used for a variety of machine screw applications, making it a valuable addition to any professional's or hobbyist’s toolkit. The plug-style tap features a tapered end with a chamfer of 3 to 5 threads, which helps to properly align and start the threading process, whether in a through-hole or a blind-hole application.

KEY FEATURES AND BENEFITS:

• Creates Accurate Threads: This tap is engineered to produce a Class 2B thread, providing a consistent and accurate fit for 6-48 NS machine screws. This ensures a strong, reliable connection in your projects.
• Reliable Performance: Constructed from high-carbon steel, the tap is built for manual hand-threading applications. It offers solid performance for both new threading and repairing existing threads in a variety of materials.
• Efficient Chip Removal: The straight flute design allows chips to move out of the hole easily during the tapping process. This reduces the risk of clogging and helps create a cleaner, more precise thread.
• Easy Identification: Each tap is etched with its size (6-48 NS) and the correct drill bit size. This clear marking saves you time and reduces the chance of using the wrong tool for your project.
• Versatile Plug Chamfer: The plug-style tap's 3-to-5-thread chamfer makes it suitable for most general-purpose tapping jobs. This design allows for easy starting and makes it an effective tool for a wide range of applications.

HOW TO USE:

1. Prepare the Hole: First, drill a hole to the recommended size for a 6-48 NS tap. The correct drill bit size is typically etched on the tap itself. Ensure the hole is clean and free of debris.
2. Apply Lubricant: Apply a small amount of cutting oil to the tap and the inside of the drilled hole. This helps reduce friction, extends the life of the tap, and creates a smoother thread.
3. Start Tapping: Insert the tap into the hole, ensuring it is as straight as possible. Use a tap wrench to apply even pressure and begin turning the tap clockwise.
4. Clear Chips: After every half-turn to full-turn, reverse the tap a quarter-turn counterclockwise. This breaks the chips and allows them to move out of the flutes, preventing the tap from binding or breaking.
5. Finish the Thread: Continue the forward and reverse motion until you have threaded the hole to the desired depth. Carefully remove the tap by turning it counterclockwise until it is free.
