Norseman Drill & Tool Letter Sizes General Purpose Type 100-BN Twist Drill Bit
Norseman Drill & Tool Letter Sizes Type 100-BN Twist Drill Bit: Built for Durability and Precision in Abrasive Drilling Applications
The Norseman Drill & Tool Letter Sizes Type 100-BN Twist Drill Bit is engineered to provide consistent, reliable performance in everyday drilling operations. Proudly made in the USA, this high-quality drill bit is designed to perform exceptionally well in mild drilling applications with strong abrasive wear characteristics, ensuring durability, accuracy, and long tool life.
Manufactured from premium high-speed steel (HSS), the Type 100-BN combines superior toughness, hardness, and cutting strength. It’s ideal for drilling materials such as mild steel, cast iron, aluminum, brass, copper, and various non-ferrous metals, as well as wood and plastic. Its heavy-duty construction allows it to resist wear and maintain its sharp cutting edge, even when working with abrasive materials.
The 118° standard point geometry ensures accurate starts, smooth penetration, and reduced walking on the work surface. The bright finish further enhances chip evacuation, improves lubricity, and minimizes friction, keeping the drill cooler and extending tool life. These features work together to provide smooth, efficient drilling in both hand-held and machine applications.
Each Type 100-BN bit is precision-ground to exact tolerances for balance, concentricity, and consistent hole sizing. Available in letter-size increments, it’s perfect for applications requiring fine hole control and professional-grade precision.
