Description
The Irwin 1/8″ x 2-3/4″ Black & Gold Drill Bit w/ Split Point (3019008B) is a high-performance tool engineered for precision and reliability. As part of the professional-grade Series 30190, this jobber length drill bit is crafted from premium high-speed steel (HSS) and features a black and gold oxide coating. This combination of materials and finish provides enhanced corrosion resistance and heat dissipation, extending the life of the bit. Its defining feature is the 135-degree split-point tip, a design that allows the bit to start drilling immediately upon contact with the workpiece, preventing the bit from “walking” or wandering. This eliminates the need for a center punch and ensures a clean, accurate hole from the very beginning. With its straight shank and robust construction, this bit is an excellent choice for a variety of materials, including high alloy steel, mild steel, sheet metal, wood, and plastic. Whether for a professional job site or a home workshop, the Irwin 3019008B delivers controlled precision and consistent results for a wide range of applications.
KEY FEATURES AND BENEFITS:
- 135° Split-Point Tip: Starts drilling instantly upon contact, eliminating bit walking and ensuring a precise, clean hole without the need for a center punch. Highly effective for portable drills and various materials.
- Black and Gold Oxide Coating: Provides enhanced resistance to corrosion and heat buildup, maintaining sharpness and structural integrity over time.
- Premium High-Speed Steel (HSS): Built for strength and longevity to withstand drilling through tough materials while retaining its cutting edge.
- Versatile Material Compatibility: Performs efficiently in high alloy steel, mild steel, sheet metal, wood, and plastic, making it a valuable addition to any toolkit.

HOW TO USE:
- Select the Right Drill: Ensure your drill is compatible with a straight shank bit of 1/8″. Secure the bit firmly in the drill chuck.
- Mark the Drilling Point: Mark the exact spot to drill; the split-point tip minimizes walking but precise marking is good practice.
- Prepare the Workpiece: Secure the material with a clamp or vise. For metal, apply cutting fluid to reduce heat and extend bit life.
- Start Drilling: Begin at slow speed, applying steady, light pressure. The split point grips and starts the hole immediately.
- Maintain Speed and Pressure: Increase drill speed once the hole starts and maintain consistent pressure. Avoid excessive force to prevent breakage.
- Clear Debris: Periodically withdraw the bit to clear chips, especially when drilling deep holes.
- Finish Drilling: Slowly withdraw the bit while the drill is spinning to ensure a clean exit hole.
