OSG Metric A-Spiral Flute Threading Tap, Left-Hand (LH), is engineered for precision blind-hole threading. Crafted from durable powder metal and TiCN-coated for wear resistance, it delivers reliable performance in demanding manufacturing environments.

• Thread size: M18 x 2.5
• Direction: Left-Hand (LH) threading for specific assembly needs
• Material: Powder metal construction for added toughness and fatigue resistance
• Coating: TiCN coating to reduce wear and lower friction during cutting
• Flute design: A-Spiral flute promotes efficient chip evacuation in blind holes
• Standards: DIN376 compatibility for standardized tapping performance
• Applications: Optimized for blind-hole threading across a range of materials

The A-Spiral flute geometry excels at removing chips from tight blind holes, helping maintain clean starts and steady cutting action. The TiCN coating enhances tool life by resisting wear in tough metals, while the powder-metal substrate provides a balance of hardness and toughness for repeated use. Ideal for automotive, industrial machinery, and precision engineering tasks where blind holes are common, this tap delivers consistent thread quality and reliable performance. Use with appropriate cutting fluid and correct tapping parameters to maximize tool life and achieve accurate, repeatable threads in DIN376 standard sizes.
