Learn more about Klarna
Description
Engineered for precise thread formation in blind holes, the OSG Metric Spiral Flute Threading Tap in M4 x 0.7 delivers dependable performance for metalworking projects that demand small-diameter, high-quality threads.
- Material & coating: HSS‑E (high-speed steel with cobalt) core with a Titanium Nitride (TiN) coating for enhanced wear resistance and longer tool life.
- Threading geometry: Metric spiral flute design optimized for efficient chip evacuation, reducing buildup in blind holes and producing cleaner threads.
- Size & thread: M4 x 0.7 threading specification, suitable for precise, metric-threaded assemblies in confined spaces.
- Application: Specifically intended for blind-hole tapping in metal components, delivering consistent thread quality where access is limited.
- Durability: Coated HSS‑E construction provides robust performance under repeated tapping cycles and helps resist wear and galling.
This tap pairs OSG’s advanced threading technology with a rugged cobalt-enhanced steel body and TiN coating to help you achieve accurate threads, smoother operation, and extended tool life—especially in tight blind-hole applications where chip control and reliability matter most.
