OSG's Metric Spiral Point Threading Tap, M4 x 0.7, is engineered for reliable through-hole threading in metalworking. Crafted from HSS-E with a Titanium Nitride (TIN) coating, it delivers durable performance and precise thread formation for demanding machining environments.

• Material & coating: HSS-E (high-speed steel with cobalt) combined with a Titanium Nitride (TIN) coating for enhanced wear resistance, reduced friction, and longer tool life.
• Size & thread: Metric thread M4 x 0.7, designed for through-hole tapping to produce accurate, consistent threads.
• Design: Spiral Point geometry facilitates efficient chip evacuation and minimizes pushing forces during cutting in through-hole work.
• Through-hole optimization: Specifically tuned for through-hole applications, delivering reliable thread formation with stable pitch and alignment.
• Craftsmanship & reliability: OSG’s precision engineering ensures tight tolerances and dependable performance in busy workshops.

The combination of cobalt-enhanced HSS-E and TiN coating delivers a robust tapping solution that withstands wear, maintains cutting efficiency, and extends service life. The spiral point geometry helps push chips forward, reducing clogging and improving productivity when threading through holes in materials such as steel, aluminum, and other common metals. This tap is ideal for shops seeking consistent, high-quality M4 x 0.7 threads with fewer tool changes and longer intervals between replacements.
