OSG Spiral Flute Tap: M20x2.5 Metric, OH2 / 6H, 4 Flute

An OSG spiral flute tap is used for threading blind holes in metal, as the spiral design pushes chips upward and out of the hole. This prevents chip clogging and allows clean threads in materials like steel, stainless steel, and aluminum. It is ideal for production machining and maintenance applications.

This OSG tap has a metric M20x2.5 thread size, a 6H tolerance class, and an OH2 surface treatment for improved wear resistance. It features 4 flutes and a modified bottoming chamfer, enabling threading close to the bottom of blind holes. The manufacturer part number is 11757.

Select an OSG spiral flute tap based on thread size, pitch, and material. For blind holes, choose a modified bottoming chamfer to thread close to the hole bottom. Match the tap tolerance (e.g., 6H) to your thread class requirement. Consider surface treatment like OH2 for longer tool life in harder materials.
