Norseman Drill & Tool Wire Gauge Sizes Type 100-BN Twist Drill Bit
Engineered for Strength, Precision, and Abrasion Resistance
The Norseman Drill & Tool Wire Gauge Sizes Type 100-BN Twist Drill Bit is built to deliver consistent accuracy, superior wear resistance, and long-lasting performance in everyday drilling applications. Proudly made in the USA, this industrial-grade bit excels in mild drilling operations where abrasive wear characteristics demand enhanced durability and clean, precise cutting.
Built for Tough, Abrasive Conditions
Manufactured from premium high-speed steel (HSS), the Type 100-BN provides an ideal balance of toughness, sharpness, and heat resistance. It performs exceptionally well when drilling mild steel, cast iron, aluminum, brass, copper, wood, and plastics, making it a versatile solution for workshops, maintenance teams, and light production environments. Its heavy-duty design resists friction and abrasive wear, helping it maintain a sharp cutting edge longer—even under repetitive use.
The 118° standard point geometry ensures smooth, accurate starts while reducing walking and improving alignment on a wide range of surfaces. This makes the bit suitable for both hand-held drills and machine drilling applications.
Precision-Ground for Consistent, Clean Drilling
A bright finish improves lubricity, enhances chip evacuation, and minimizes material buildup. These features help keep the bit cooler during operation, resulting in cleaner cuts and extended service life. Each Type 100-BN drill bit is precision-ground to exact tolerances, ensuring excellent concentricity, balance, and uniform hole sizing across all wire gauge increments.
