OSG Threading Tap - Metric Spiral Flute HSS-E - Steam Oxide Coated - Blind Hole - M3.5 x 0.6

The OSG Threading Tap - Metric Spiral Flute HSS-E - Steam Oxide Coated - Blind Hole - M3.5 x 0.6 is a precision tool designed for engineers, machinists, and fabricators who need reliable internal threads in tight, blind-hole applications.

• Size and pitch: M3.5 x 0.6 threading tap for accurate, repeatable internal threads in blind holes.
• Material: HSS-E (high-speed steel with cobalt) delivers enhanced hardness and heat resistance for demanding tapping tasks.
• Coating: Steam oxide coating reduces friction and provides wear protection to extend tool life in hot cutting conditions.
• Flute design: Spiral flute geometry promotes efficient chip evacuation, minimizing clogging in blind-hole work.
• Application focus: Specifically optimized for threading in blind holes, ensuring clean starts and consistent thread quality.
• Technology: Utilizes OSG’s advanced threading technology to deliver stable performance and reliable results across multiple setups.

When you’re machining small, enclosed threads, this tap delivers consistent, high-quality results with fewer insertions and less torque. The combination of HSS-E material and steam oxide coating supports longer tool life under higher cutting temperatures, while the spiral flute design keeps chips moving away from the threading zone. Ideal for precise, repeatable threads in metal components where space is limited and surface finish matters.
