The OSG Metric A-Spiral Flute Threading Tap is a high‑performance tool designed for threading blind holes with precision in small-diameter applications. Built for manufacturing professionals, it delivers reliable, consistent results across a range of materials.

• Size: M1.4 x 0.3 thread size for fine-pitch applications
• Flute design: A‑spiral flute optimizes chip evacuation in blind holes
• Material: Powder metal body for strength and wear resistance
• Coating: TiCN coating increases surface hardness and reduces friction
• Thread direction: Right-hand thread standard for most tapping operations
• Standards: DIN371 compliant for reliable interchangeability
• Applications: Suited for high-speed production environments and deep/blind hole tapping

The combination of a TiCN-coated powder-metal body and an A‑spiral flute translates into longer tool life and predictable performance. The TiCN coating reduces wear and allows higher cutting speeds with less heat buildup, while the powder metal substrate provides toughness for repeated cycles. The flute geometry clears chips efficiently in blind holes, reducing the risk of breakage and improving thread accuracy. This tap is ideal for miniature assemblies, electronics housings, and precision mechanical components where a clean, reliable M1.4 x 0.3 thread matters. For best results, pair with proper lubrication and standard tapping practices to maximize tool life and thread quality.
