OSG Metric A-Spiral Flute Threading Tap, Left-Hand, TiCN-coated, is built for precise blind-hole threading. Designed for professional use, this tap delivers dependable performance in demanding applications where left-handed threads and tight tolerances matter.

• Threading Type: Left-Hand (LH) threading tap for applications requiring reverse-thread operation and specific assembly requirements.
• Flute Design: A-Spiral flute engineered to efficiently evacuate chips in blind holes, reducing clogging and improving cutting stability.
• Material: Powder metal construction offering enhanced toughness and wear resistance for extended tool life.
• Coating: TiCN coating to lower friction, resist wear, and improve surface finish in tougher materials.
• Size: M22 x 2.5 standard for metric threading, suitable for common industrial fastener specifications.
• Standards: DIN 376 compatible for reliable interchangeability with other DIN-standard threading tools.
• Applications: Effective across a range of materials commonly encountered in machining, including steel, stainless steel, cast iron, and aluminum alloys.
• Brand: OSG, a trusted name in precision threading tools with a focus on consistency and quality.
• Use Case: Optimized for accurate blind-hole threads where chip evacuation and hole cleanliness are critical to thread integrity.

These features translate into real-world benefits: longer tool life from a durable powder-metal body and TiCN coating, cleaner and more consistent threads in blind-hole geometries, and reliable performance across multiple materials. The combination of the A-Spiral flute and left-hand design supports smoother cutting, better hole quality, and reduced downtime due to tool wear or chip buildup—making it a practical choice for workshops and production environments that demand precision and durability from their threading tools.
