ISO HSS‑M2 Round Shank Nut Tap is a dedicated industrial nut tap conforming to ISO standard. Tool blank material is premium HSS‑M2 high‑speed steel. The whole threaded cutting section is finished with TiN (Titanium Nitride) gold coating to reduce friction, resist built‑up edge and extend tool service life under non‑stop production cycles.
Different from standard machine taps with square driving shank, this nut tap adopts square‑tail‑free round shank, designed to be clamped by collet chucks of special nut tapping machines. Long continuous flutes run across the full cutting length, delivering stable chip removal for continuous through‑threading of nuts in mass‑production environment.
Core Specifications
Standard: ISO Standard
Base Material: HSS‑M2 High‑Speed Steel
Surface Coating: TiN (Titanium Nitride Coating)
Shank Type: Round Shank, no square tail
Flute Design: Long Continuous Flute
Application: Dedicated for nut internal threading
Key Features
✅ ISO Standard Specification: Consistent thread accuracy for nut manufacturing
✅ HSS‑M2 High‑Speed Steel Substrate: Great toughness for long‑run continuous machining
✅ TiN Gold Coating: Increased surface hardness, lower friction, anti‑adhesion and longer tap life
✅ Round Shank without Square Tail: Designed for collet chuck mounting on special nut tapping machines
✅ Long Continuous Flutes: Optimized chip flow for nut through‑hole threading
✅ High‑volume production oriented: Ideal for nut factory mass‑production operations
Application Scenarios
Specifically developed for high‑volume internal threading of hex nuts. Works with dedicated nut‑tapping machine tools for carbon steel nuts, alloy steel nuts and other ferrous‑material nut production.
Note: This is nut‑special tap with round shank, NOT for general‑purpose standard tap holders with square drive.
Usage Note
Constant supply of suitable tapping cutting fluid is strongly recommended to dissipate heat, minimize tool wear and improve thread surface quality during long‑time mass production.
