Norseman Drill & Tool Fractional Sizes Reduced Shank GOLDSTRIKE™ Type 190-GFR Twist Drill Bit
Heavy-Duty Precision for Handheld Drilling
The Norseman Drill & Tool Fractional Sizes Reduced Shank GOLDSTRIKE™ Type 190-GFR Twist Drill Bit is engineered to provide maximum strength, precision, and convenience for professionals who rely on handheld drilling tools. Proudly Made in the USA, this premium drill bit is built to deliver outstanding performance in demanding environments where accuracy, durability, and efficiency matter most.
Built for Tough Materials and Extreme Conditions
Manufactured from premium high-speed steel (HSS), the GOLDSTRIKE™ Type 190-GFR delivers exceptional cutting power and resilience. Its heavy-duty construction makes it ideal for drilling through:
-
Stainless steel
-
Hardened and high-tensile alloys
-
Abrasive metals
-
Heat-resistant materials
Engineered to withstand extreme drilling conditions, this bit maintains sharpness, reduces heat buildup, and resists wear—even during prolonged or high-load operation.
Reduced Shank for Versatility in Handheld Tools
The reduced shank design enables users to drill larger hole diameters using standard 3/8" or 1/2" drill chucks, including popular handheld drills with keyless chucks. This provides:
-
Greater versatility
-
Faster bit changes
-
Secure, vibration-resistant operation
Whether on the jobsite or in a fabrication shop, the 190-GFR offers the adaptability needed for real-world drilling challenges.
TiN Coating for Maximum Tool Life
Enhanced with a durable Titanium Nitride (TiN) coating, this bit delivers superior:
-
Surface hardness
-
Lubricity
-
Heat resistance
-
Wear protection
The TiN finish improves chip evacuation, reduces friction, and supports cooler, faster cutting—resulting in longer tool life and cleaner hole quality.
Precision-Cut Performance
Its 135° self-centering split point ensures quick, accurate starts, minimizes walking, and reduces thrust pressure—critical when drilling in tight spaces or on angled surfaces.
