Irwin 31/64" x 5-7/8" Black & Gold Drill Bit w/ Split Point (3019031B)

The Irwin 31/64" x 5-7/8" Black & Gold Drill Bit w/ Split Point (3019031B) is a high-performance cutting tool designed for professionals and tradespeople who require precision and efficiency when drilling into metal. This jobber-length drill bit is manufactured from high-speed steel, ensuring its strength and longevity in demanding applications. The bit features a distinct black and gold oxide finish, which serves a dual purpose of providing enhanced corrosion resistance and reducing friction and heat buildup during use. The key to its superior performance lies in its 135° split point design. This geometry allows the bit to self-center upon contact with the workpiece, preventing the common problem of "bit walk" and ensuring a clean, accurate hole from the very beginning. This eliminates the need for a center punch, saving valuable time and improving the overall quality of the work. The Irwin 3019031B is an essential tool for drilling through tough materials such as high-carbon steel, ferrous metals, and low-carbon stainless steel, making it a reliable choice for a wide range of industrial and workshop tasks.

KEY FEATURES AND BENEFITS:

• 135° Split Point Tip: Allows the drill bit to start drilling immediately on contact, preventing it from walking or skating across the surface of the material, ensuring accurate hole placement without a pre-punched pilot hole.
• High-Speed Steel Construction: Made from HSS, known for hardness and the ability to retain a sharp cutting edge at high temperatures for longer life and better performance on hard metals.
• Black & Gold Oxide Finish: Black oxide provides rust and corrosion protection, while gold oxide reduces friction and heat for improved efficiency and extended bit life.
• Jobber Length Design: Offers a balance between reach and stability, making it versatile for handheld drills and drill presses.

HOW TO USE:

1. Safety First: Always wear safety glasses and appropriate protective gear before operating any power tool.
2. Select the Correct Drill: Ensure your drill is compatible with a straight shank bit and set to the correct speed for the material. Use slower speeds for harder metals.
3. Secure the Bit: Insert the bit into the drill chuck and tighten firmly to prevent slipping.
4. Mark the Spot: Position the tip on the exact drilling location. The split point will help prevent walking.
5. Begin Drilling: Apply steady pressure without forcing. Start at a slow speed and increase gradually.
6. Use Cutting Fluid: Apply cutting oil, especially on tough metals, to cool the bit and improve performance.
7. Clear Chips: Back the bit out periodically to clear chips and prevent clogging.
8. Finish: Withdraw the bit while the drill is running to avoid catching.
