Irwin Hanson 1465 1 Inch-8 NC High Speed Steel Plug Tap

The Irwin Hanson 1465 is a high-quality plug tap designed for creating or restoring 1-inch internal threads with a National Coarse (NC) pitch of 8 threads per inch. Manufactured from premium high-speed steel (HSS), this tap delivers exceptional durability and clean, precise threads in a wide range of materials including steel, aluminum, brass, and other metals.

Key Features:

• 1-inch diameter with 8 threads per inch (NC thread standard)
• High-speed steel construction for extended tool life and heat resistance
• Plug tap design with 3-5 thread chamfer for general-purpose applications
• Precision ground threads ensure accurate thread formation
• Suitable for through-hole and blind-hole threading operations
• Right-hand cutting direction (standard)

Plug taps are the most commonly used tap style and are ideal for both hand tapping and machine operations. The moderate chamfer length allows the tap to start easily while providing sufficient thread engagement for most applications. This tap is an essential tool for maintenance, repair, and manufacturing operations requiring coarse thread production in larger diameter holes.
