Engineered for precision threading in blind holes, the OSG Metric Spiral Flute Threading Tap combines HSS-E cobalt steel with a steam oxide coating to deliver durable, heat-resistant performance for demanding metalworking tasks. Designed for professionals tackling M14 x 2 threads, it delivers reliable, consistent results across challenging materials.

• Size: M14 x 2
• Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance
• Coating: Steam oxide coating to improve durability and heat resistance
• Flute design: Spiral flute for efficient chip evacuation, especially in blind holes
• Application: Optimized for precise threading in blind-hole applications

The combination of a cobalt-enhanced core and robust coating means sharper cutting edges stay sharper longer, allowing for higher cutting speeds and more dependable performance in tougher metals. The spiral flute geometry actively evacuates chips away from the cutting zone, reducing the chances of clogging or breakage in blind-hole tapping. This leads to cleaner threads, fewer reworks, and longer tool life on critical machining tasks—from automotive components to precision assemblies.
