OSG Threading Tap - Metric Spiral Flute HSS-E - Steam Oxide Coated - Blind Hole - M36 x 4

The OSG Metric Spiral Flute Threading Tap in M36 x 4 is a purpose-built solution for precision internal threading in blind holes, designed for professional metalworking environments that demand reliability and long tool life.

• Size and pitch: Internal thread tap for blind holes, M36 x 4, enabling robust, large-diameter threads with a 4 mm pitch.
• Material: HSS-E (high-speed steel with cobalt) for enhanced toughness and heat resistance during heavy cutting.
• Coating: Steam oxide coating reduces friction and wear, helping maintain sharpness and extend service life in demanding cuts.
• Flute geometry: Spiral flute design optimized for efficient chip evacuation, especially effective in blind-hole environments where chips can trap.
• Application: Ideal for high-precision internal threading in tough materials such as alloy steels and structural components, ensuring consistent thread quality in critical assemblies.
• Durability and consistency: Engineered to deliver stable performance and repeatable results across multiple parts, reducing rework and downtime.

This tap solves the challenge of creating clean, accurate threads in blind holes where bottom clearance is limited. The combination of HSS-E, steam oxide coating, and a spiral flute enhances heat tolerance, minimizes wear, and promotes smooth chip removal, helping machinists achieve reliable thread engagement in automotive, machinery, and industrial fabrication applications. For best results, use appropriate cutting fluid to maximize tool life and finish.
