The OSG Threading Tap is a precision metric tooling solution designed for clean, reliable threading of blind holes. Built for machining professionals and shops that demand consistency, it combines durable powder-metal construction with a high-efficiency A-Spiral flute and a hard TiCN coating to extend tool life in demanding production environments.

• Thread size: M1.8 x 0.35, designed for precise metric threading per DIN371
• A-Spiral flute: Optimizes chip evacuation in blind holes for deeper, smoke-free cuts
• Material: Powder metal body delivers notable strength and wear resistance
• Coating: TiCN coating increases surface hardness and reduces friction for longer tool life
• Hand: Right-hand (clockwise) threading for standard machining setups
• Applications: Ideal for tapping blind holes in a variety of materials with consistent results

This tap is engineered to maintain stable performance from the first thread to the last, even in deep or hard-to-reach blind holes. The combination of a robust powder-metal body and a TiCN-coated cutting edge minimizes built-up edge and wear, supporting repeatable thread quality in high-speed production. The A-Spiral flute design helps evacuate chips efficiently, reducing clogging and supporting precise, smooth tapping in tight cavities. Whether you're refurbishing equipment or fabricating parts with blind-hole features, this tool delivers reliable results with reduced downtime and predictable outcomes.
