Norseman Drill & Tool Fractional Sizes Type 100-BN Twist Drill Bit
Superior Durability for Mild Drilling Applications with Abrasive Wear
The Norseman Drill & Tool Type 100-BN Twist Drill Bit is engineered to deliver exceptional durability, stable performance, and long tool life in general-purpose drilling tasks—especially where abrasive wear is a concern. Proudly made in the USA, this drill bit is designed for professionals who require dependable cutting performance in materials that accelerate edge wear.
Built for Abrasive Drilling Conditions
High-Speed Steel Strength with Long-Lasting Edge Retention
Manufactured from premium high-speed steel (HSS), the Type 100-BN combines toughness with enhanced wear resistance, making it ideal for mild drilling applications where abrasion shortens the life of standard drill bits. It performs exceptionally well in:
-
Mild steel
-
Cast iron
-
Aluminum
-
Brass and copper
-
Wood and plastics
Its rugged construction ensures the bit maintains its cutting edge longer, even when drilling abrasive materials or working in high-friction environments.
118° Standard Point for Smooth, Accurate Starts
Reliable Performance in Hand-Held or Mounted Equipment
The 118° standard point geometry provides clean starts, reduced walking, and controlled cutting action. This makes the Type 100-BN suitable for both hand drills and drill presses, delivering smooth, predictable drilling performance across varied materials and applications.
Bright Finish & Precision Grinding
Cooler Cutting and Consistent Hole Quality
A bright finish enhances chip evacuation, reduces friction, and helps dissipate heat—critical when drilling abrasive surfaces. Each bit is precision-ground to strict tolerances, ensuring excellent balance, consistent hole sizing, and long-term reliability.
