Irwin 4-40 NC Plug Tap & #43 Drill Bit Tap and Drill Bit Set (80209)

The Irwin 4-40 NC Plug Tap & #43 Drill Bit Tap and Drill Bit Set (80209) is the ultimate solution for anyone needing to create precise threaded holes. This set provides the two essential tools required for a successful threading job: a high-carbon steel plug tap and a high-speed steel drill bit. Designed to work in perfect harmony, the #43 drill bit creates the precise hole needed for the 4-40 NC tap to cut clean, strong threads. This eliminates the guesswork of finding the right size drill and ensures a professional finish every time.

KEY FEATURES AND BENEFITS:

• Creates Precise 4-40 NC Threads: The included high-carbon steel plug tap is specifically designed to cut 4-40 National Coarse threads, widely used for various fastening applications.
• Correct Hole Size: The #43 high-speed steel drill bit ensures the pre-drilled hole is perfectly sized for optimal thread formation, preventing broken taps and providing strong, clean threads.
• High-Quality Materials: Tap is made from high-carbon steel for excellent performance and long-lasting sharpness; drill bit is made from high-speed steel for fast and accurate drilling.
• All-in-One Convenience: This two-piece set provides both tap and drill bit in a single package, saving time and effort searching for compatible tools.
• Versatile Application: Suitable for professional metalworking, automotive jobs, home repair projects, and model building.

SPECIFICATIONS:

• Tap Size: 4-40 NC
• Drill Bit Size: #43
• Tap Material: High-Carbon Steel (HCS)
• Drill Bit Material: High-Speed Steel (HSS)
• Included in the Set: 1x 4-40 NC Plug Tap, 1x #43 Drill Bit

HOW TO USE:

1. Prepare the Material: Mark the exact location for the threaded hole. Secure the material in a vise or clamp to prevent movement.
2. Drill the Hole: Insert the #43 high-speed steel drill bit into your drill. Drill a straight, clean hole on the marked spot. Use lubricant when drilling metal to extend bit life and improve cut quality.
3. Align the Tap: Place the tip of the 4-40 NC plug tap into the drilled hole. Ensure the tap is vertical and aligned properly to create straight threads.
4. Begin Tapping: Use a tap wrench to turn the tap clockwise. Apply slight downward pressure initially to start threading. Reverse direction every half-turn to break chips and avoid binding.
5. Finish Tapping: Continue turning and reversing until the tap reaches the desired depth or passes through the material. Remove the tap carefully by turning counter-clockwise and clean out any chips.
