The OSG Threading Tap is a precision M4 x 0.7 tap designed for reliable blind-hole threading in demanding metalworking applications. Built with a Form E A-Spiral Flute and TiCN coating, it delivers extended flute length, strong wear resistance, and efficient chip evacuation for deep-hole tapping.

• Thread size & standard: M4 x 0.7 metric thread, DIN371 compatibility for broad, interchange-ready use.
• Flute design: A‑Spiral flute (Form E) with an extended flute length tailored for tapping deeper blind holes.
• Material: Powder metal body delivering high strength, toughness, and dependable wear resistance.
• Coating: TiCN coating enhances surface hardness, reduces friction, and extends tool life during demanding operations.
• Working direction: Right-hand design suitable for a wide range of threading setups and machines.
• Application focus: Specifically optimized for blind holes, with spiral geometry that promotes continuous chip removal and lowers the risk of tap breakage.

Designed to improve productivity and thread quality in deep, closed-end pockets, this tap combines durable construction with a coating that sustains higher cutting speeds and longer intervals between tool changes. The extended flute length supports reliable engagement in deeper holes, while the TiCN coating helps maintain performance across repeat cycles, making it a dependable choice for routine blind-hole tapping and precision assemblies.
