Norseman Drill & Tool Type 130-D Fractional Sizes Silver & Deming Drill
Cobalt Strength for the Toughest Drilling Applications
The Norseman Drill & Tool Type 130-D Silver & Deming Drill is engineered for high-performance drilling in some of the hardest and most heat-resistant materials used in manufacturing today. Made from M42 super high-speed cobalt steel, this fractional-size drill bit offers exceptional red-hot hardness, edge retention, and durability—making it a top choice for aerospace, fabrication, machining, and heavy industrial environments.
Premium Cobalt Construction
Built for Extreme Heat and Hard Metals
With its M42 cobalt composition, the 130-D maintains cutting efficiency at temperatures far beyond the limits of standard HSS. This allows operators to drill up to 30% faster without sacrificing accuracy or tool life. It excels in difficult materials such as:
-
Work-hardening stainless steel
-
High-temperature alloys
-
Titanium and titanium-grade metals
-
Hardened steels
-
Certain high-density plastics
135° Split Point for Quick, Accurate Starts
Reduced Walking and No Pilot Hole Required
The 135° split point ensures clean, walk-free starts and superior penetration, even in hard surfaces. Combined with a gold surface finish, the drill provides enhanced lubricity, reduced friction, and cooler cutting—critical for extending tool life in production settings.
Silver & Deming Versatility
Large-Diameter Drilling with Standard Chucks
A 1/2" reduced shank allows large-diameter drilling using standard drill chucks, making the Type 130-D suitable for drill presses, milling machines, and rigid positive-feed equipment. Because cobalt drills are designed for controlled feed rates, they perform best in stable, well-supported drilling conditions.
