The OSG Metric Spiral Point Threading Tap is a precision tool designed for through-hole threading, delivering dependable performance for small-diameter parts in professional workshops and precision shops.

• Thread size: Metric spiral-point tap for M1 x 0.25 through-hole threads, engineered for accurate, clean taps.
• Material: HSS‑E (high-speed steel with cobalt) for superior hardness, wear resistance, and heat tolerance during demanding cuts.
• Coating: Steam oxide coating enhances surface durability and tool life in high-heat tapping operations.
• Geometry: Spiral-point design promotes rapid chip evacuation and consistent thread formation in through-hole applications.

This combination of material, coating, and geometry translates to fewer tool changes, smoother thread production, and reliable performance across multiple holes. Ideal for precision assemblies, prototypes, and repeatable manufacturing tasks requiring small-diameter metric threads.
