Norseman Drill & Tool Fractional Sizes Type 100 Twist Drill Bit
Built for Strength, Precision, and Abrasion Resistance
The Norseman Drill & Tool Fractional Sizes Type 100 Twist Drill Bit is engineered to deliver dependable performance, long-lasting durability, and smooth cutting action across a wide range of general-purpose drilling applications. Proudly made in the USA, this high‐quality bit is specifically designed for mild drilling tasks where abrasive wear resistance is essential—making it a trusted choice for maintenance professionals, fabricators, and production environments.
Durable Construction for Abrasive Materials
Manufactured from premium high-speed steel (HSS), the Type 100 offers superior toughness, heat resistance, and cutting stability. Its strong edge retention allows it to excel when drilling abrasive materials such as cast iron, copper, brass, aluminum, and other non-ferrous metals. It also performs exceptionally well in wood, plastics, and composite materials, providing clean, accurate holes with minimal surface distortion.
The 118° standard point geometry ensures smooth starts, reduces walking, and improves hole placement accuracy—perfect for hand-held or machine drilling. This versatile point design enhances control and efficiency in both light-duty and moderate drilling operations.
Precision-Ground for Superior Performance
A bright finish reduces friction, enhances chip evacuation, and helps prevent material build-up and overheating. This not only improves drilling efficiency but also extends the bit’s overall service life. Each Type 100 bit is precision-ground to exact tolerances, ensuring perfect balance, smooth operation, and consistent results across all fractional sizes.
