OSG Metric A-Spiral Flute Threading Tap, LH, is engineered for precision blind-hole threading. Crafted from high-grade powder metal and TiCN-coated for exceptional wear resistance, this tap delivers reliable cutting performance across a variety of metals.

• Material: Powder Metal substrate provides toughness and long tool life under demanding threading tasks.
• Coating: TiCN coating increases hardness and reduces wear, helping the tool stay sharp longer between regrinds.
• Flute Design: A-Spiral Flute enables efficient chip evacuation in blind holes, minimizing clogging and improving thread quality.
• Thread Type: Left-Hand (LH) threading for applications that require reverse-direction tapping.
• Size and Pitch: M8 x 1.25, a common metric size for internal threads in standard assemblies.
• Standards: DIN371 compliant, ensuring consistent geometry and compatibility with DIN tooling ecosystems.
• Application: Suitable for a range of materials, delivering reliable internal threads in challenging blind-hole environments.

Designed to promote cleaner, more accurate blind-hole threads, this tap reduces risk of chip packing and tool wear while extending service life. The combination of powder-metal toughness, TiCN hardness, and the A-Spiral flute’s superior chip evacuation translates to steadier feeds, smoother cuts, and fewer reworks. Ideal for machinists and shops that prioritize precision, durability, and consistent results in internal threading tasks.
