Norseman Drill and Tool Type 20 Fractional HSS Spiral Point Plug Taps
Norseman Type 20 Fractional Spiral Point Taps
Precision Threading for Softer Materials
The Norseman Drill and Tool Type 20 Fractional Spiral Point Tap is a professional-grade threading tool designed for clean, accurate threads in softer materials like aluminum, wood, plastic, brass, and mild steel. Made in the USA from high-speed steel (HSS), this tap delivers durability, sharp cutting edges, and long service life in both hand and machine operations.
Its bright finish improves chip flow and reduces galling, making it ideal for tapping soft or ductile materials without clogging or excessive wear.
Spiral Point Geometry for Through-Hole Tapping
Efficient Chip Evacuation and Smooth Threading
The spiral point design, often referred to as “gun taps,” pushes chips forward and out of the hole. This prevents chip buildup and allows for continuous, high-speed threading, especially in through-hole applications.
-
Optimized for through-holes in soft metals and plastics
-
Ensures smooth chip removal and reduced binding
-
Minimizes torque for longer tap life
Bright Finish Enhances Performance in Soft Materials
Improved Lubricity and Chip Flow
The bright finish provides a smooth surface that enhances performance in low-hardness materials. It aids in chip flow, prevents material adhesion, and reduces the risk of chip packing or thread distortion.
-
Ideal for aluminum, plastic, wood, and brass
-
Helps maintain sharp cutting edges
-
Delivers clean, burr-free threads
Fractional Sizing for American Industry Standards
Available in UNC and UNF fractional thread sizes, Norseman Type 20 Spiral Point Taps are a reliable choice for machine shops, fabricators, and contractors who need consistent, high-quality threads in everyday materials.
