Irwin 5/8″-18 NF HCS Fractional Tap – Bulk (1354)

Description

The Irwin 5/8″-18 NF HCS Fractional Tap – Bulk (1354) is a precision tool engineered for manual threading applications. This taper tap is part of a versatile family that includes plug and bottom taps, catering to various threading depths and needs. Made from high carbon steel, it provides a dependable and efficient solution for maintenance, repair, and rethreading tasks. The tap is specifically designed for hand threading work in a range of materials such as mild steel, aluminum, and brass, making it a staple for any workshop or professional toolkit. Its straight flute design is optimized for rapid chip removal, ensuring a clean and effective threading process.

KEY FEATURES AND BENEFITS:

• High Carbon Steel Construction: The use of high carbon steel provides the necessary hardness and durability for effective hand threading in various materials, ensuring a longer tool life.
• Straight Flute Design: The straight flutes are specifically ground to facilitate rapid and efficient chip removal. This prevents clogging and ensures a cleaner thread, reducing the effort required for tapping.
• Taper Tap Style: The longer chamfer on the taper tap makes it easy to start new threads accurately, especially in blind holes or for through-hole applications. This feature minimizes the risk of crooked or misaligned threads.
• General-Purpose Threading: This tap produces a Class 2B thread, which is the industry standard for a general-purpose fit. This makes it a versatile tool suitable for a wide range of common fastening applications.
• Ideal for Maintenance and Repair: Engineered specifically for hand threading work, this tap is perfectly suited for routine maintenance, repair tasks, and rethreading existing holes, providing a reliable solution without the need for specialized power equipment.

SPECIFICATIONS:

HOW TO USE:

1. Preparation: Drill a hole of the correct tap drill size for a 5/8″-18 NF thread. The diameter of this hole is crucial for a clean, strong thread.
2. Lubrication: Apply a suitable cutting fluid or lubricant to both the tap and the hole. This will reduce friction, prevent the tap from overheating, and extend its life.
3. Start the Tap: Place the taper tap into the hole. Use a tap wrench to hold the tap securely and ensure it is perfectly perpendicular to the surface.
4. Initial Turns: Apply firm, even pressure while slowly turning the tap clockwise (for right-hand threads). Turn the tap a couple of times to get the threads started, making sure to check for perpendicularity.
5. Tapping: Continue turning the tap clockwise, making sure to turn it backward by about half a turn for every full turn forward. This backward motion breaks the chips and prevents them from binding the tap, allowing for clean chip removal.
6. Completion: Continue this process until the tap has passed through the material (for through holes) or reached the desired depth (for blind holes). Remove the tap by turning it counterclockwise.

BENEFITS OF USING IRWIN 5/8″-18 NF HCS FRACTIONAL TAP – BULK (1354):
