Designed for precision metric threading in blind holes, the OSG Threading Tap Metric Fine A-Spiral Flute delivers clean, accurate cuts and extended tool life for demanding machining tasks.

• Thread size & pitch: M22 x 2 with metric fine pitch for precise, tight-thread results in blind holes
• A-Spiral flute design: Efficient chip evacuation in blind holes to reduce clogging and cutting resistance
• Substrate material: Powder metal construction for enhanced wear resistance and durability
• Coating: TiCN coating increases hardness and reduces friction for smoother cuts at higher speeds
• Thread direction: Right-hand thread compatibility with standard tapping operations
• Application: Optimized for DIN 374 blind-hole threading, delivering consistent internal threads
• Brand: OSG—trusted for reliable, precision threading tools

In practical use, this tap excels where clean thread formation in confined cavities matters most. The spiral flute moves chips upward and out of the hole, minimizing chip packing and reducing the likelihood of cross-threading. The TiCN coating helps maintain cutting performance as speeds rise and temperatures increase, while the powder metal substrate stands up to wear in repeated tapping cycles. Together, these features enable repeatable, accurate M22 x 2 threads in blind holes across automotive, aerospace, mold making, and general engineering applications.
